Pre-Hardmode Bosses

    Desert Scourge 
https://static.tvtropes.org/pmwiki/pub/images/desert_scourge_0.png
The desert sand stirs...

Once a mighty ocean worm that destroyed the Ocean Kingdom, its home has been dried up by Calamitas and it has been forced to become a desert worm. It's the first Calamity-exclusive boss available when you start the game, and has to be fought in the Desert.

The Desert Scourge drops various water-themed weaponry/equipment, and gives all the ingredients required to make Victide Bars, an early crafting material required to make beginner-level equipment. It also has a very small chance to drop the Dune Hopper and Deep Diver, the rare variants of the Scourge of the Desert and Shield of the Ocean respectively. Killing it also allows the blocks in the Sunken Sea to be mined, allowing true access into the biome.


  • Art Evolution: It went from a blue worm into a drier-looking brown worm, which looks more terrifying than its old sprite.
  • Contractual Boss Immunity: Unlike the vanilla worm bosses, the Desert Scourge reduces the damage of piercing weapons with every segment they pierce, which massively reduces the damage they would normally cause to it - a trait shared by a number of the Calamity worms and the Revengeance/Death Mode versions of the vanilla worms.
    • In addition, it massively resists explosive weapons in Expert and above.
  • Dishing Out Dirt: In Revengeance Mode, it gains the ability to rapidly fire sand blasts at players.
  • Eyeless Face: Appears to just have empty sockets instead of actual eyes.
  • Flunky Boss: Summons Dried Seekers as you damage it.
  • Foreshadowing: Its lore makes mention that it was weakened due to a lack of food and water, exactly what the Aquatic Scourge actually does have.
  • How the Mighty Have Fallen: This thing went from being a force capable of wiping out an entire kingdom to a dried-up, early-game boss.
  • Leitmotif: Guardian of the Former Seas.
  • More Teeth than the Osmond Family: Both sprites have plenty of teeth.
  • Names to Run Away from Really Fast: Ironically, it's the easiest Calamity Boss.
  • Sand Worm: That used to be a water worm, no less.
  • Segmented Serpent: Likely the first Worm boss a player will fight.
  • Wake-Up Call Boss: As a worm enemy, it's very hard to dodge its attacks unless you have some sort of vertical mobility or dash. The earliest you can get an accessory that lets you dash is after beating the Eye of Cthulhu, the very next boss, and in the early-game very few items that enhance your vertical mobility are readily available.
  • Worf Had the Flu: Pretty much why it's fought so early: Its home has been dried up, and it's been weakened by living in an environment with little water.
  • Wolfpack Boss: In Revengeance, you have to fight 3 of them at once.

    Crabulon 

https://static.tvtropes.org/pmwiki/pub/images/crabulon_6.png

A giant crab from the same evaporated ocean that the Desert Scourge came from. After its home was incinerated, it migrated to the Glowing Mushroom biome, only to perish and become a host to parasitic fungi. Must be fought in the Mushroom Biome.

Crabulon drops numerous mushroom-themed weapons, and drops the Mushroom Plasma Root in Revengeance which permanently boosts your Rage Mode damage.


  • Art Evolution: The new sprite is much more accurate to normal crabs, with a lot more detail as well.
  • Body Horror: It's the dried-up, decaying body of a dead ocean crab that has become a home and vessel to countless parasitic mushrooms that have filled up the husk of its body.
  • Death from Above: Its arcing shots of exploding mushrooms can sometimes cause this, and it also rains drifting Crab Shrooms from the sky as an attack. In Revengeance Mode and higher, it can sometmes summon evenly spaced walls of mushrooms that fall from the sky.
  • Empty Shell: Only the barest scraps of meat remain in its parasite-ridden husk, the mushrooms festering within compelling it to move and feed even in death.
  • Expy: Its design coupled with its new lore can bring Parasect to mind.
  • Festering Fungus: It has been infected with parasitic fungi, akin to the Cordyceps.
  • Flunky Boss: While Crabulon is capable of directly fighting you, most of the challenge in its fight comes from the fact that it fires out huge clumps of Mush Bombs that descend across the screen and deal massive damage when they hit the player.
  • Giant Enemy Crab: Well, yeah. Downplayed because it isn’t as big as many other bosses, but it still towers over the player.
  • Leitmotif: 1NF3S+@+!0N.
  • Mushroom Man: Downplayed, being a crab and all, but still.
  • Our Zombies Are Different: It's the decaying corpse of an ocean-dwelling crab that is now controlled by parasitic mushrooms.
  • Puppeteer Parasite: The mushrooms growing all over it are actually what control it.
  • The Last of These Is Not Like the Others: The only one of the pre-Hardmode bosses to have a leitmotif without a guitar in it.
  • Ultimate Life Form: Its former lore entry described it as this.

    The Hive Mind 

https://static.tvtropes.org/pmwiki/pub/images/hive_mind.png
Rotten cysts are oozing from the corrupt land...
Click here to see its second phase 

A giant colony of Eater of Souls, roughly shaped like a brain, that serves as a means of spreading and sustaining the Corruption. Notably, it can be spawned naturally after destroying a Hive Cyst, which is an uncommon enemy that spawns in the Corruption.

It drops dark-themed equipment, along with True Shadow Scales which are used to make higher-level Corruption gear. Killing it (or its Crimson counterpart) generates Aerialite Ore in your world.


  • Art Evolution: The eyes on its body don't resemble the eyes of Eaters of Souls anymore, now having turned into Yellow Eyes of Sneakiness. It also gained four small legs that it uses for landing, two tubes that constantly pump out Corruption in its first phase, its "crown" is now composed of 6 True Shadow Scales that twitch during the fight. And it now has holes all over its head, which would definitely bring Trypophobia to mind. Oh, and it has become smaller, too.
  • Brain Monster: A giant grey brain-like atrocity made up of rotting flesh and pockmarked with holes all over the body, with a crown made of True Shadow Scales.
  • Body of Bodies: This thing is made up of countless Eater of Souls that have merged together into this monstrosity.
  • The Darkness Gazes Back: Its second form invokes this, with its eyes lighting up within the numerous holes in its body.
  • Death from Above: In its second form, it can produce rain clouds that rain down plagued rain whenever it dashes.
  • Flunky Boss: Spams various Corrupt enemies as it loses health, which include Hive Blobs, Dank Creepers, Dark Hearts, Eaters of Souls and Devourers.
  • Hive Mind: Hey, it's in the name.
  • Leitmotif: The Filthy Mind.
  • Lightning Bruiser: While it is normally quite slow in its second form, it can perform some extremely fast dashes and maneuvers to compensate.
  • Load-Bearing Boss: Subverted. Yharim presumes that killing the Hive Mind will not put an end to the Corruption. And it shows; upon defeating the Wall of Flesh, which, by that point, the player should've killed the Hive Mind by now, the spread rate of the Corruption actually intensifies just like in the vanilla game.
  • Marathon Boss: The battle tends to play out like this; It's got high health and teleports a lot, but will also hit you pretty infrequently.
  • Stationary Boss: During its first phase, it is completely immobile save for the occasional teleport, and has to rely on swarms of Mooks to defend itself.
  • Stone Wall: Its first phase, where contact damage is very minimal and it cannot move, but has a fair amount of health and enemies to keep the player distracted.
  • Suspiciously Similar Substitute: To the Brain of Cthulhu from the base game. The similarity used to be even stronger, as the Hive Mind and Brain of Cthulhu once shared a very similar AI.
  • Teleport Spam: Can do this in its stationary form to get the jump on unwary players. The second form takes it Up to Eleven, with the Hive Mind teleporting and dashing at the same time to confuse its foes.
  • The Corruption: Well, of course it hails from it, but the Hive Mind in particular is stated to be able to spread and maintain the Corruption wherever it goes.
  • The Worm That Walks: A colony of creatures travelling in a group, combining their abilities to form a much more powerful being.
  • Turns Red: Once you deplete its first health bar, it uproots itself and begins rapidly charging at players while teleporting.
    • If you exit the Corruption, the Hive Mind will become almost immune to damage.
  • Yellow Eyes of Sneakiness: Hive Mind's eyes in its second phase resembles this.

    The Perforators 

https://static.tvtropes.org/pmwiki/pub/images/perforators_6.png
Bloody cysts are erupting from the crimson's flesh...

A trio of worms that were once a single large worm, before adapting to live in the Crimson and becoming parasites within the Brain of Cthulhu, which turned into the Perforator Hive once it was destroyed. Notably, they can spawn naturally after killing a Perforator Cyst, which is an uncommon enemy that spawns in the Crimson.

They drop equipment based around blood and flesh, and also drop Blood Samples which are used to make higher-level Crimson gear. Killing it (or its Corruption counterpart) generates Aerialite Ore in your world.


  • Art Evolution: The Perforator Hive has become a lot more mushroom shaped, with faces with rows of sharp teeth across its body and a shifting eye in the center. The worms, on the other hand, look much more terrifying than before by having their own Body Horror amplified.
  • Back from the Dead: The Perforator Hive (used to) resemble a floating chunk of the Brain of Cthulhu. Considering that the Perforators used to be parasites within the Brain of Cthulhu before it died...
  • Bloody Murder: The Perforator Hive's main attack, shooting a shotgun spread of blood into the air to rain down on the player.
  • Body Horror: Good lord. Not only do all of the Perforators look grotesque as all hell, resembling twisting and infectious masses of raw flesh with far too many eyes and teeth, the Perforator Hive has an attack that inflicts a debuff named Burning Blood. Its tooltip? "Your blood is on fire". It's literally causing your blood to boil while you're still awake and alive.
  • Bread, Eggs, Breaded Eggs: The Crimson + The Corruption = This atrocity.
  • Cyclops: Arguably the only trait it retains with the Brain of Cthulhu.
  • Damage-Increasing Debuff: Its golden shots inflict Ichor, which massively reduces your defenses.
  • Damage Over Time: The Perforators are the only enemies in the game to inflict the Burning Blood debuff, which deals damage over time and hammers you with numerous effects (some of which are, strangely, positive).
  • Death from Above: The Perforator Hive's main attack is raining red or golden blasts from above that inflict the Burning Blood or Ichor debuff.
  • Didn't Think This Through: Their lore states that after losing their old host, they now desire to use the player as their new one. Considering how much smaller the player is compared to the Perforator worms, whether that would work out or not is uncertain at best.
  • Eyes Do Not Belong There: Both the Hive and the Worms are covered in Yellow Eyes of Sneakiness. Strangely enough, the lore states that the worms lost their need for eyes, implying that those smaller eyes are non-functional (the Hive is the only one with a proper eyeball).
  • Flunky Boss: Every time the Perforator Hive takes enough damage, it spawns one of the Perforators proper to assist it. It will spawn them in order from weakest to strongest - the largest worm in particular must be killed to finish off the Hive.
  • Fragile Speedster: The first Perforator Worm, with the lowest attack and health but the highest speed.
  • Gameplay and Story Integration: The lore for the Perforators states that they were parasites within the Brain of Cthulhu before it was killed. Sure enough, their hive's old sprite resembled half of the Brain of Cthulhu flipped on its side.
  • Jack-of-All-Stats: The second Perforator Worm, with middling stats in comparison to the other two.
  • Kill One, Others Get Stronger: As more Perforator Worms die, the surviving ones gain speed and attack boosts.
  • Lamprey Mouth: The largest worm has this.
  • Leitmotif: Blood Coagulant.
  • Meaningful Name: Named after the Perforator veins. Can also be a Double Meaning, as to perforate is to pierce/make holes in something, like how the worms would pierce out of the ground, supported by the first Perforator's needle-like mouth.
  • Mighty Glacier: The last Perforator Worm, the strongest and tankiest but also the slowest.
  • My Blood Runs Hot: Capable of forcing this onto you with their exclusive Burning Blood debuff, which deals Damage Over Time and provides a number of varied effects.
  • Overdrawn at the Blood Bank: If all of those blood and ichor shots from the Perforator Hive are any indication.
  • Puppeteer Parasite: The Perforators evolved into this inside the Brain of Cthulhu. If they lose their host, they burrow as a group to the depths of the crimson and wait for a new host to come across them. Unluckily for you, their new host is you.
  • Segmented Serpent: The Perforators, obviously.
  • Yellow Eyes of Sneakiness: Their resprites gave all of them this, the worms in particular having numerous that somewhat resemble the Hive Minds.
  • You Don't Look Like You: Said to be the reanimated Brain of Cthulhu, but the resprite heavily changed the hive's design to make them look more distinct.

    The Slime God 

https://static.tvtropes.org/pmwiki/pub/images/the_slime_god.png
Blighted sludge spreads throughout the world's evil...

A mutated bacterium that absorbed enough matter to become the godlike control unit of all slimes, who created the Ebonian and Crimulan Slime Gods to protect it from all possible threats.note . It is the final Pre-Hardmode boss in the mod, and is intended to be fought right before the Wall of Flesh.

The Slime God drops slime-themed weapons and Purified Gel, which is used to make Statigel armor and other slime-themed weapons. In Revengeance, it notably drops Purified Jamnote  (which allows players to become temporarily impervious to harm) and the Electrolyte Gel Pack (which permanently shortens your Adrenaline charging time).


  • The Assimilator: It gained intelligence by consuming other beings, until it eventually gained telekinesis as well.
  • Asteroids Monster: Each lesser Slime God can split into 2 when at half health. They'll also shed lesser slimes as they take damage.
  • Blob Monster: Of course.
  • Flunky Boss: Not only does the Slime God delegate most of the fighting to the Crimulan/Ebonian Slime Gods, even those can summon waves of minions when hurt.
  • Fragile Speedster: The Slime God Core is incredibly fast and hits like a truck, but it has rather low HP - only 8,400 even in Death Mode.
  • From Nobody to Nightmare: From a simple bacterium to a massive and immensely powerful god. Yharim himself fears what would happen if it was allowed to assimilate all slimes on Terraria, deeming that the resulting entity would be nearly unstoppable.
  • Gravity Screw: Getting hit by the Slime God Core will inflict the Distorted debuff, causing you to float in midair and making it harder to dodge the Slime Gods' attacks.
  • Grenade Spam: Both Slime Gods and the Core can fire colored orbs that linger in the air before exploding.
  • Kill One, Others Get Stronger: Depending on which Slime God you take down first, the others get unique boosts.
    • Killing the Crimulan Slime God first will cause the Ebonian Slime God and all Ebonian Slimes to start attacking and charging far more frequently.
    • Killing the Ebonian Slime God first will give the Crimulan Slime God and all Crimulan Slimes large defense boosts, as well as making the Crimulan Slime God shoot mines much faster.
    • Killing the Slime God Core first will allow the lesser Slime Gods to perform extremely fast charges whenever they go offscreen.
    • If you take down both lesser Slime Gods before the core, the Slime God proper completely changes his attack patterns, attempting to ram you and launching barrages of lingering mines.
  • Leitmotif: Return to Slime.
  • Lightning Bruiser: The Ebonian/Crimulan Slime Gods are far faster than you think they are.
  • Magic Knight: All three Slime Gods possess powerful melee and ranged attacks, the Ebonian Slime God leaning towards stronger ranged shots while the Crimulan Slime God has stronger defenses.
  • Monster Progenitor: This thing is responsible for the creation of every slime you see in the world.
  • Shielded Core Boss: The actual Slime God was invulnerable until the other two Slime Gods are killed, but this was rectified as of a new update.
  • Standard Status Effects: Infamous for liberally spamming these. The lesser Slime Gods inflict these, with both Slime Gods inflicting Mana Sickness (reduces magic damage), the Crimulan Slime God and its minions inflicting Cursed in Expert and above (stops you from using items), and both inflicting Brimstone Flames (a Damage Over Time effect that deals 40 HP/sec). The Slime God proper inflicts some more... unorthodox conditions, however.
  • Time Abyss: The Slime God itself was one of the very first creatures to ever exist in the world, which likely makes it centuries to millennia old.

Minibosses

    Cnidrion 
https://static.tvtropes.org/pmwiki/pub/images/cnidrion_0.png

A two-legged seahorse-like miniboss found in the Underground Desert that possibly hails from the former ocean where the Desert Scourge and Amidias came from. It drops materials to make Victide Bars and an accessory which allows you to release an explosion of sparks when damaged.It also has a miniscule chance to drop The Transformer, the rare variant of Amidias' Spark.


  • Art Evolution: It has become from a seahorse with legs into a brown, drier-looking one just like the Desert Scourge. Combined with its hind legs, it has become more akin to a horse, fitting for its implied nature as a Seahorse Steed.
  • Armless Biped: It has a pair of hind legs, but it has no forelegs.
  • Butt-Monkey: When it appeared as though it had a boss theme made for it, it turned out to be a Halloween joke, with the Devourer of Gods breaking in to steal the show. Two months later, it’s confirmed it wasn’t getting a theme.
  • Leitmotif: Subverted. It gets a grand total of five seconds of "Seahorse Scrutiny" before the entire forest burns to a crisp. Few months later, DM DOKURO says he will not be getting a theme.
  • Making a Splash: Fires barrages of water shots at the player.
  • Jump Scare: Is one of the few pre-hardmode monsters that can move through blocks, causing this sometimes.
  • Seahorse Steed: Implied, given that it looks like it’s wearing something akin to a horse tack.
  • Unexpected Character: At first, it appeared to have its own theme being made, but this was actually a joke, being a set up for Devourer of Gods' final form's theme.

    Giant Clam 
https://static.tvtropes.org/pmwiki/pub/images/giant_clam.png
A massive clam miniboss found in the Sunken Sea. If Amidias isn't present in the world, he'll fall out of the Clam once it's killed (assuming you've killed the Desert Scourge). When Hardmode rolls around, the Clam gets massive stat buffs, as well as several new attacks.

Drops an accessory in pre-Hardmode, along with another on Revengeance+. In Hardmode, it starts to drop a number of aquatic weapons, as well as Mollusk Husks.


  • Death from Above: In Hardmode, it gets the ability to summon a row of energized pearls that fall down on players from above.
  • Enemy Summoner: When it becomes aggressive, it will inflict the Clamity debuff on players, which massively boosts Clam spawn rates and makes them aggressive as well. However, it makes all other enemies unable to spawn.
  • Flunky Boss: In addition to increasing Clam spawn rates, it can directly spawn Clams to help it.
  • Gemstone Assault: In Hardmode, it can fire bursts of psychic pearls for its new attacks. These are either summoned in falling rows or directly fired in radial/aimed bursts.
  • Gentle Giant: It's huge, but it won't attack unless struck five times.
  • Ground Pound: Can teleport above the player and attempt to perform this.
  • Stationary Boss: Outside of occasional teleportation, it doesn't move.
  • Took a Level in Badass: When Hardmode begins, it gains huge stat increases and revamped attacks.

    Cloud Elemental 
https://static.tvtropes.org/pmwiki/pub/images/cloud_elemental_56.png
A hardmode miniboss akin to the Sand Elemental, originally revered as a deity like the other Elementals, and just like them, forgotten with the passage of time. Found at the Floating Islands or the Ocean. Drops a beam sword and an accessory which allows you to summon her as an ally. Post-Providence, they get a miniscule chance to drop the Thunderstorm, the Plasma Rifle's rare variant.
  • Art Evolution: She was originally a lot more blue, with less large eyes. Her hair also looked more akin to a tornado than cumulus clouds. Her third resprite gives her a new set of armor and a somewhat slimmer form.
  • Blow You Away: Attacks the player with three tornado shots.
  • Cute Monster Girl: A curvy woman made of clouds.
  • Elemental Embodiment: Of wind.
  • Fog Feet
  • Foil: To the Sand Elemental from the original game. The Sand Elemental is thin, has higher amount of immunities to status effects, is associated with sand, and is part of the actual game. The Cloud Elemental is relatively pudgy, has higher overall stats, is associated with air, and is from a mod of said game. Before the latter’s sprite change, the two had contrasting eye colors as well.
  • Full-Frontal Assault: She lacks clothing, as well as genitalia.
    • Averted with her resprite, which gave her armor.
  • God Needs Prayers Badly: In the same boat as the other Elementals.
  • Hartman Hips
  • High-Heel–Face Turn: She’s a summonable Minion through the Eye of the Storm accessory.
  • How the Mighty Have Fallen: Given that she’s one of the Elementals.
  • Mighty Glacier: Somewhat slow, but pretty tanky and can hit hard with her tornado attacks.
  • She's Got Legs: Her old sprites tended to emphasize her large legs. Not so much anymore, since she no longer has any.
  • Shock and Awe: She holds a lightning bolt in her hand, but she never uses it.
  • Took a Level in Badass: Gets a significant stat buff once Providence is slain. This is due to the fact that at this point in time, it becomes able to drop the Thunderstorm.
  • Underground Monkey: More or less one to the Sand Elemental, given that she shares the same attack, is a Hardmode miniboss and has near identical stats.

    Earth Elemental 
https://static.tvtropes.org/pmwiki/pub/images/earth_elemental.png
A hardmode miniboss found in the Underground and Cave layers, and another one of the elementals. Originally a part of a scrapped boss idea. Drops several earth-themed weapons and a consumable which allows you to summon a Sandstorm.
  • An Axe to Grind: Its arms are shaped like massive axes.
  • Armor Is Useless: Despite being visually covered in battle armor, it has the lowest HP of all the Elementals.
  • Art Evolution: Arguably the most drastic one, from a winged, two legged horse to a massive, humanoid set of armor.
  • Blade Below the Shoulder: Its arms are gigantic stone axes.
  • Bullfight Boss: Its primary attack beyond flying into the player is to charge at them.
  • By the Lights of Their Eyes: Only one of its eyes is visible as its only possible facial feature.
  • Cute Monster Girl: Defied. It’s a monstrous humanoid made of stone.
  • Dishing Out Dirt: Can fire bursts of explosive rocks along with its physical attacks.
  • Elemental Embodiment: Of earth.
  • Gladiator Games: Its overall design resembles a gladiator's set of armor. This may coincide with its previous design being a horse.
  • Glass Cannon: Less defenses and health than the Cloud Elemental, but hits harder.
  • Glowing Eyes of Doom: Shows a single glowing eye through its helmet.
  • Guys Smash, Girls Shoot: It is this given the other Elementals are female and focus more on ranged attacks, while the Earth Elemental mostly uses physical rams and only uses projectiles as a secondary attack.
  • Fragile Speedster: Surprisingly quick given its size and can deal good damage, but doesn't have exceptionally high health.
  • Heel–Face Turn: Averted. It lacks a summoning item that would make it a minion like the other Elementals,
  • Jump Scare: Its ability to phase through the ground can cause these.
  • The Last of These Is Not Like the Others: Runs on this trope. The Cloud, Sand & Brimstone Elementals and the Siren are Cute Monster Girls who focus on using ranged attacks and can be summonable minions. The Earth Elemental is a monstrous armored humanoid that likes to attack targets by ramming into them, and can’t be summoned due to it lacking such an item.
  • No-Sell: Immune to knockback.
  • Ramming Always Works: It tries to attack the player by flying at them.

    Armored Digger 
https://static.tvtropes.org/pmwiki/pub/images/armored_digger.png
A mechanical worm miniboss that starts spawning underground after Plantera is slain. Drops Demonic Bone Ash, and has a chance to drop Draedon's Remote. It also has a very small chance to drop the Lead Wizard, the rare variant of the Clock Gatlignum.
  • Anti-Frustration Features: If you leave the underground biome to escape it, the Armored Digger will immediately flee and despawn shortly after.
  • Achilles' Heel: Despite its high stats, it's still a worm, and it lacks the piercing resistance that most Calamity worm bosses have. This makes it highly vulnerable to piercing weapons like spears.
  • An Ice Person: Although it has no ice-related abilities, direct contact with it will inflict Chilled.
  • Art Evolution: Used to be silver-and purple, looking more like a miniature Devourer of Gods. Now, it's a detailed, red-and-silver worm.
  • Boss in Mook Clothing: It's way tougher than pretty much any enemy that can show up at that point of the game, for sure. In addition, like the Adult Eidolon Wyrm, an awakening message will pop up when it spawns, which is normally reserved for full-fledged bosses.
  • Lightning Bruiser: The thing is massive, packs a ton of HP, and hits fairly hard, all while being deceptively agile and capable of attacking from multiple angles. Worse still, the caves where it spawns are usually quite tight, making avoiding the worm difficult.
  • Segmented Serpent: For a mere miniboss, the Armored Digger is massive.
  • Shock and Awe: Can occasionally discharge a large amount of electrified debris from its body as its sole ranged attack. These will linger on the ground for some time before dissipating. In addition, direct contact with the worm will inflict Electrified.
  • Took a Level in Badass: Was promoted from a common post-Plantera enemy to a relatively tough, full-fledged miniboss.

    Great Sand Shark 
https://static.tvtropes.org/pmwiki/pub/images/gss3.png
A miniboss that can be found during post-Plantera sandstorms in the Desert every time you kill 20 Sand Sharks. It can also be spawned manually using a Sandstorm's Core. Always drops a Grand Scale, which is a material used to upgrade several items.
  • Dishing Out Dirt: Every time it leaps out of the sand, it can send up a shower of damaging sand blasts.
  • Flunky Boss: Can start summoning Sand Sharks when below 50% HP. On Expert and above, it'll start spawning them at 75% HP instead.
  • King Mook: Of the Sand Sharks and its variations from the vanilla game. It'll even show up if you kill 20 of the Sand Sharks in a sandstorm.
  • Land Shark: Swims through the sand, waiting for unsuspecting prey.
  • Lightning Bruiser: For how agile it is and how hard it hits, it's quite bulky at 12,800 HP on Expert+.
  • Ramming Always Works: Its only attacks are various ramming moves. It can perform both horizontal and vertical leaps, and can even redirect itself in midair for a surprise attack.
  • Sand Is Water: Swims through it just like water.
  • Scary Teeth: Huge and sharp ones.
  • Threatening Shark: A land shark at that.
  • Underground Monkey: Averted. There are no Corruption, Crimson or Hallowed versions of it like the normal Sand Sharks.
  • You Will Not Evade Me: If you stray too far from it, it'll charge straight towards you at top speed until it returns to your vicinity.

    Plaguebringer 
https://static.tvtropes.org/pmwiki/pub/images/plaguebringer.png
A plague has befallen the Jungle...
The standard infantry units for Yharim’s army, being plagued Queen Bee corpses intertwined with machinery. The heavy artillery variant, the Plaguebringer Goliath, serves as their King Mook. Spawns in the Jungle randomly after Golem has been defeated, and drops Plague Cell Canisters.
  • Boss in Mook Clothing: A surprisingly tough miniboss, formerly the hardest one to fight. The record has since been topped by the Abyssal Minibosses, with the Mauler being even more damaging than the Plaguebringer and having 12 times more HP than it.
  • Bee Afraid
  • Degraded Boss: Inverted. They're weaker versions of the Plaguebringer Goliath that appear before the boss itself. In fact, it is required to kill regular Plaguebringers in order to craft the summoning item for the Plaguebringer Goliath.
  • Flunky Boss: Can summon small groups of Plague Chargers to assist it in battle.
  • Lightning Bruiser: Like the Plaguebringer Goliath, it is fast, relatively sturdy and can strike the player with tough blows, both from its rams and its ranged rocket/stinger attacks.
  • Macross Missile Massacre: While not as extreme as its boss variant, it can still fire off quite a storm of ordnance.
  • Names to Run Away from Really Fast
  • Palette Swap: Nearly identical to Plaguebringer Goliath, with green eyes and a slightly lighter shade of black for its body.
  • Plague Master: They’re infamous for this, spreading it wherever they go.
  • Poisonous Person: By extension of the above trope.
  • Sickly Green Glow: The recurring theme for Plaguebringers, present even in their coloration.
  • Warm-Up Boss: More or less served as this for the actual Plaguebringer Goliath, who fights similarly to the standard units.

    Abyssal Minibosses 
The abyssal spirits have been disturbed...

A number of the creatures that lurk in the deepest regions of the Abyss are strong enough to be considered Minibosses on their own. Most of them will only retaliate if attacked or approached, and most of them drop unique items in addition to the standard Post-Plantera Abyss drops of Depth Cells and Lumenyl. The Mauler is an exception, living in the Sulphurous Sea above the Abyss instead.


  • Boss in Mook Clothing: All of them. They pack stats comparable to endgame bosses.
  • Leitmotif: All of them minus the Mauler share Threats of the Ocean Floor.
    • Or at least they were supposed to, before the song got scrapped.
  • Sea Monster
  • Wolfpack Boss: Not only do they have a tendency to spawn together, they can and will gang up on you given half the chance.
  • Rare Random Drop: If you're playing on Revengeance Mode or higher, the Halibut Cannon. While all Abyss monsters in Revengeance+ have a minuscule chance (0.1%) to drop the gun, the Abyssal Minibosses can drop it at an increased rate of 1%. The Adult Eidolon Wyrm in particular has a further increased drop chance, at 10%.

Mauler

https://static.tvtropes.org/pmwiki/pub/images/mauler_4.png
A massive, mutated shark which lives in the Sulfurous Sea. It uses incredibly dangerous melee strikes and can also spit acid blasts. If lured out of the water long enough, it'll explode violently. Drops Shark Fins and a ranged weapon post-Polterghast.
  • Anti-Frustration Features: The Mauler spawn rate scales with how far you are in the game, ranging extremely rare in pre-hardmode to fairly common after Moon Lord. While it is still possible to get jumped and instantly killed by a Mauler near the start of the game, it's very unlikely.
  • Art Evolution: Got a more polished sprite that gives it a more jagged appearance.
  • Boss in Mook Clothing: Even though it's just a miniboss, and arguably the weakest of the Abyssal Minibossesnote , it still has more health than the Aquatic Scourge, which is the actual boss of the biome.note 
  • Jump Scare: What differentiates the Mauler from the other Abyss minibosses is that it spawns on the surface. While you have to dive all the way down to the bottom layers of the Abyss to find the other bosses, this one can spawn the instant you try to enter the area. Combine this with the fact that it can spawn at any time in the game, new players are sure to get jumped by this thing at least once.
  • Lightning Bruiser: It has a whopping 360,000 HP, can deliver lethal blows instantly, and swims incredibly fast. It can even take massive leaps out of the water to surprise unwary players.
  • Poisonous Person: Spits acid to attack from range.
  • Taking You with Me: If you take it out of water for too long, it will explode into a massive nova of acid that's liable to kill any players standing too close to it when it happens. It also drops no loot as a result.
  • Threatening Shark: An acid shark.

Colossal Squid

https://static.tvtropes.org/pmwiki/pub/images/colossal_squid.png
A gigantic, pale squid which resides in the third layer of the Abyss. A deceptively fast, bulky creature, it attempts to crush players underneath it with large leaps towards them. Uniquely drops Black Ink and a powerful summon weapon post-Polterghast.
  • Anti-Frustration Features: If you have a Colossal Squid latched onto you, it will reduce your Aggro stat by so much that it becomes virtually impossible for anything else to target you during this time.
  • Everything's Squishier with Cephalopods: A gigantic white squid that lives in the ocean depths.
  • Giant Squid: Specifically, a Colossal Squid. The actual Giant Squids in the Abyss are far more benign.
  • Grenade Spam: Fires balls of ink which explode into lingering ink clouds.
  • Interface Screw: Can latch onto the player and greatly reduce their field of vision while dealing constant damage.
  • Lightning Bruiser: The thing packs 440k HP (in Expert and above) and is surprisingly fast for its bulk, all the while hitting like a runaway freight train on steroids.

Reaper Shark

https://static.tvtropes.org/pmwiki/pub/images/reaper_shark_3.png

A predatory beast that spawns in the third and fourth layers of the Abyss, armed with a potent cloaking ability. Reaper Sharks will remain invisible until provoked, upon which it will aggressively ram into players. Always drops a Cloaking Gland to make Anechoic Coating, and can drop Reaper Teeth used for certain equipment. Post-Polterghast, it will begin dropping a deadly throwing weapon as well. They also have a small chance to drop The Reaper, the rare variant of the Valediction.


  • Art Evolution: Mere days after its release one was made for it, looking considerably more muscular and brutish.
  • Blade Below the Shoulder: There are evident elbow blades on the Reaper Shark's arms.
  • Expy: While it's not evident in as many ways as the Eidolon Wyrm, it does bring the Reaper Leviathans from Subnautica to mind, especially with its incredibly aggressive behavior and Lightning Bruiser nature.
  • Extra Eyes: Has four eyes.
  • Hell Is That Noise: They will emit a low, echoing roar if it draws too close to you or if you attack it.
  • Invisibility: It has the ability to cloak itself, with it only uncloaking if enraged.
  • Lightning Bruiser: It's decently fast, deceptively bulky and can easily shave off massive chunks of HP with each strike.
  • Meaningful Name: Its tail, which can be looted from it as a weapon named "Valediction", looks like a sickle, which is the signature weapon of The Grim Reaper.
  • Sea Monster: A vicious, shark-like predator with invisibility powers.
  • Turns Red: When at half HP, it will begin to use constant, rapid charges like Duke Fishron.
  • Signature Roar: A deep, watery rumble that is one of the only ways to detect it before it attacks you.
  • Threatening Shark: One with fists to boot.

Eidolon Wyrm

https://static.tvtropes.org/pmwiki/pub/images/smallworm.png
Juvenile Eidolon Wyrm
https://static.tvtropes.org/pmwiki/pub/images/bigworm.png
Adult Eidolon Wyrm

Massive, ghastly sea serpents that spawn in the third and fourth layers of the Abyss and are armed with a wide array of deadly attacks. They will only attack if struck first. While the smaller juveniles can spawn anytime, the gigantic and more powerful adults will only spawn after Polterghast is killed (unless you use the Rod of Discord in the Abyss, which force-spawns an enraged Adult).

Both of them will drop a number of items post-Polterghast, most notably an extremely dangerous magic gun and sword.


  • An Ice Person: They have the ability to fire frozen spikes like Lunatic Cultist's at any would-be aggressors.
  • Art Evolution: Twice, the first resprite having the Juveniles and the Adults getting their separate sprites while making them look less like Ghost Leviathans, then another resprite that gave them a more intricate and detailed look.
  • Attack Its Weak Point: Attacks will phase right through them unless they hit its head. On the flip side, an Eidolon Wyrm's head is the only part of its body that can deal contact damage to you.
  • Berserk Button: Using the Rod of Discord in the Abyss will not only immediately spawn an Adult Eidolon Wyrm near you, but instantly trigger its aggressive state as well.
  • Bonus Boss: Both of them never need to be fought unless you want their rewards.
  • Boss in Mook's Clothing: The Juvenile packs incredible defense, dangerous attacks, and has the HP to match. The Adult, on the other hand, is by far the strongest Miniboss in the game and one of the strongest entities in the game, period. Not only does it have its attack power magnified exponentially (to the point where it can often One-Hit Kill an endgame player), but it boasts a whopping 1,000,000 HP and takes 1 damage from anything.
  • Damage-Sponge Boss: Packing 1,000,000 HP, the ability to reduce all attacks to Scratch Damage, and Hitbox Dissonance making only its head vulnerable, an Adult Eidolon Wyrm isn't going down without some serious effort on your part.
  • Expy: They're essentially Ghost Leviathans from Subnautica, except with unexplained magical powers, two of which are similar to the Lunatic Cultist's for whatever reason.note  Their resprites made the resemblance less obvious, but it's still quite evident.
    • In terms of their behavior and purpose, the Adults were designed to be like the Dungeon Guardian from the first game - seemingly unstoppable entities with obscene defense, blocking you from performing a task (entering the Dungeon early for the former, using the Rod of Discord in the Abyss for the latter) and punishing you with a world of pain if you attempt it anyways. However, the Adults are leagues more powerful than the Dungeon Guardian due to their higher damage, wider variety of attacks and massively increased health.
  • Gentle Giant: Despite their enormous size and deadly combat abilities, Eidolon Wyrms are completely harmless until you attack them first - which stands out since most Abyss enemies will attack you if you draw too close. The only exception to this rule is the Adult Eidolon Wyrm spawned by using the Rod of Discord in the Abyss, which is always aggressive.
  • Hell Is That Noise: The Juveniles' horrific, almost human-like shrieking isn't the nicest thing to hear in the depths of the Abyss. The Eidolic Wail weapon they drop allows you to turn this on your enemies by using their shrieks as sonic weaponry.
  • Lightning Bruiser: The Adults are surprisingly fast for their size and can hit you for enough damage to One-Hit Kill anyone not wearing endgame armor - and that's not putting its magic attacks and immense durability into account. The Juveniles, while much weaker, are still nothing to sneeze at either.
  • Marathon Boss: Even with skill and the right selection of endgame weapons, taking down an Adult Eidolon Wyrm is going to take a long time.
  • Mind over Matter: They can occasionally fling the player in a random direction through telekinesis. The Adult's telekinetic power is much stronger.
  • Sea Monster: Massive and terrifying sea serpents that possess strange, incredibly lethal powers.
  • Segmented Serpent: As worms, this comes with the territory, however unlike most worms its head is the only part that can deal damage and be damaged. The Adult Eidolon Wyrm deserves mention for being absolutely massive.
  • Shock and Awe: They can summon giant Magnet Spheres that fire lightning bolts at their foes, much like the Lunatic Cultist.
  • Signature Roar: A horrific echoing screech for the Juvenile, and a deep wail for the Adult.
  • Super Toughness: The Adult akes Scratch Damage from all attacks, a la Dungeon Guardian.
  • The Juggernaut: The Adults combine this and Implacable Man. With its relentless chasing, massive HP and defenses, obscene contact damage, and devastating magic attacks, if one starts chasing you usually only one of you are going to make it out alive - and it's usually not going to be you.
  • There Is No Kill Like Overkill: An Adult Eidolon Wyrm has 3000 defense on top of 99.99% damage reduction, making it nearly impossible to do significant damage to it.
  • Turns Red: Using a Rod of Discord in the Abyss will not only summon an enraged Adult, but immediately make all living Eidolon Wyrms aggressive and aware of your location.

Hardmode Bosses

    Cryogen 

https://static.tvtropes.org/pmwiki/pub/images/cryogen_13.png
The ancient ice spirits have been unbound!
Click here to see Phase 2 

After the archmage Permafrost refused to help Yharim's plans, Yharim sealed him, along with his castle and magic, in a frozen prison that transformed in the creature called Cryogen. Sealed away by Yharim after he realized it was too powerful and erratic for him to control, it has been released at the genesis of Hardmode. It is the first boss intended to be fought once Hardmode starts, and can only be fought in the Snow biome.

Drops a number of ice-based equipment, and also drops Frigid Bars which can be used to craft hardmode equipment. It also has a rare chance to drop the Regenator, the rare variant of the Ornate Shield. Killing Cryogen also causes Cryonic Ore to generate within your world, and allows the Archmage to move in.


  • Action Bomb: Throughout its battle, it summons small snowflake-like bombs that explode into showers of icicles.
  • Animate Inanimate Object: A giant ice cube with crystals around it to look like a snowflake.
  • An Ice Person: Well, what did you expect from an oversized living snowflake?
  • Art Evolution: Its new sprite is much more detailed than its old one, and it gets a separate sprite for its second phase.
  • Beam Spam: Its primary means of attack are radial bombardments of freezing blasts.
  • Confusion Fu: Has a whopping total of six phases, with a different attack pattern in each.
  • Death from Above: Starting from its second phase, it can try to rain icicles down on the player if they are below it. In addition, one of its later attacks has it launching spreads of icicles into the air, which crash down on enemies.
  • Empathic Environment: As it nears death, it starts snowing harder and harder.
  • Everything's Better with Spinning: In its last phase it starts to spin erratically.
  • Flunky Boss: Summons Cryocores and Aurora Spirits as it loses health.
  • Heel–Face Turn: After destroying Cryogen, the freed Permafrost joins you as an NPC.
  • Leitmotif: Antarctic Reinforcement.
  • Marathon Boss: It has six phases, more than the True Final Boss of the vanilla game! And it's only the first Calamity boss in hardmode...
  • Ramming Always Works: Its last phase has it abandon all of its projectiles and simply try to fly right into you at top speed.
  • Regenerating Shields, Static Health: Cryogen has an ice barrier that must be destroyed before damaging it, which will also explode into a burst of shots when broken. It will regenerate several moments after being destroyed.
  • Shows Damage: In its last phase, its central crystal visibly cracks and crumples.
  • Teleport Spam: Will do this in his semifinal phase.
  • Turns Red: In Expert Mode, its damage and defense rise as it takes more damage.
  • Was Once a Man: Cryogen used to be the Archmage of Ice Permafrost, Yharim's most bitter enemy, but after Permafrost refused to help Yharim he was destroyed by Yharim's magic and reborn as a mindless hunk of magical ice.

    Brimstone Elemental 

https://static.tvtropes.org/pmwiki/pub/images/eab11726_4ac5_4413_af01_c3b1bb997b3f.gif
Every rose has its thorn. This one's thorns just happen to make you die a horrible, fiery death.
A demonic elemental that used to be revered as a god, who eventually lost power after humanity began to lose faith in her. She is summoned in the mod-exclusive Brimstone Crags. Gains a buff in stats if Providence is defeated.

Drops a number of brimstone weapons and accessories, and also drops Bloodstone and a special mount after Providence is killed.


  • Art Evolution: Overall looks like a more polished version of its older sprite.
  • Cheerful Child: The Brimling summon, stated to be a younger Brimstone Elemental, is adorable.
  • Curb-Stomp Battle: Was on the recieving end of one courtesy of Calamitas when she invaded the Underworld, due to being far weakened by a lack of faith.
  • Cute Monster Girl: It's a woman made of fire that has a rose made of brimstone for a lower body.
  • Cyclops: Sources say Brimstone Elemental was originally to have two eyes that fuse into one while she attacks, now she is a full on cyclops.
  • Death from Above: One of her phases has her try to fly above the player while launching brimstone fireballs, which create large lingering explosions on impact with blocks.
  • Defeat Equals Friendship: If you collected her Rose Stone, you can summon her to fight for you.
  • Defend Command: For one of its phases, it will retreat into its shell and become nearly immune to damage. You simply have to outlast it as it fires waves and waves of projectiles at you.
  • Elemental Embodiment: Of fire, specifically that of the Underworld.
  • Full-Frontal Assault: It's completely naked, yet lacks any genitalia or nipples.
  • Flaming Hair
  • Flunky Boss: In Revengeance Mode and above, she maintains a small squad of Brimlings during combat, which teleport around and unleash fireballs of their own at you. If one is killed, it will respawn instantly and briefly enrage the Elemental.
  • Gods Need Prayer Badly: As humanity began to reject the Elementals as they lost faith in them figured out the secrets of their magic, the Elementals in turn lost power to the point of many of them fading away, and the ones who survived were severely weakened.
  • High-Heel–Face Turn: Joins the player as a summonable minion if you obtained the Rose Stone.
  • How the Mighty Have Fallen: She and her “sisters” make it look like Desert Scourge had it easy. Originally praised as goddesses, they lost their followers as the years went by. Unlike the others, however, Brimstone Elemental got it even worse, when Calamitas rained havoc on the underworld where the Brimstone Elememtal thrived, now rendered weak and vengeful against humanity.
  • Leitmotif: Left Alone.
  • Playing with Fire / Casting a Shadow: Uses brimstone fire attacks, which inflict a seriously damaging debuff called Brimstone Flamesnote . Come Revengeance+, and her shots also inflict Abyssal Flames, which is even worsenote .
  • Teleport Spam: Can do this in one of her phases. For good measure, she leaves explosive dust clouds in her wake.
  • Took a Level in Badass: Gains a large boost in stats when Providence is defeated.
  • Turns Red: Kill one of her Brimlings, and she'll enrage for a short time. To make matters worse, they'll respawn instantly.

    Aquatic Scourge 
https://static.tvtropes.org/pmwiki/pub/images/aquatic_scourge.png
The sulphuric sand stirs...

The distant relative of the Desert Scourge mutated by the sulphuric waters above the Abyss. Due to its adaptations to thrive in the sulphuric ocean and an ample food supply, it is noticeably less hostile in comparison to its starved cousin. It can only be fought in the Sulphurous Sea, and can uniquely spawn by itself, although regardless of its spawning methods it will be passive until struck.

The Aquatic Scourge simply drops beefed-up versions of Desert Scourge's equipment.


  • Early-Bird Boss: Much like The Siren/Leviathan, the Aquatic Scourge can rarely spawn at any point in the game, including Pre-Hardmode. Unlike the Siren, however, it aggroes instantly if you hit it even once, so if you have any enemies that spawned before it spawned and the boss is circling around you...
  • Flechette Storm: Can fire a large number of homing needles to skewer you with.
  • Flunky Boss: Rapidly spawns Aquatic Seekers, Aquatic Parasites and Aquatic Urchins as it takes damage.
  • Gameplay and Story Integration: The Aquatic Scourge is essentially the Desert Scourge before its home was dried up. As such, not only does it fight like a much stronger Desert Scourge, but its drops are just souped-up versions of the Desert Scourge's own drops.
    • Also mentioned is its lessened aggression. Sure enough, it won't attack unless hit first.
  • Gentle Giant: While it is huge and quite powerful, it won't attack unless attacked first. Justified because unlike the Desert Scourge, it's not desperate for food.
  • Helpful Mook: Like other bosses, its presence prevents other enemies from spawning. However, it can spawn naturally and it won't attack unless hit first, making fishing much less stressful.
  • Homing Projectile: It rapidly fires homing needles at the player to attack.
  • Leitmotif: Outcast of the Sulphurous Seas.
  • Making a Splash: Rapidly fires blasts of sulphuric water to attack.
  • Poisonous Person: Can leave behind clouds of toxic gas as it moves.
  • Recurring Boss: A stronger, hydrated version of the Desert Scourge.
  • Segmented Serpent: Much like its predecessor. And if its lore item is any indication, the one you fight is apparently still a juvenile.
  • Team Pet: Served as this for the moderators/cool guys’ server, preventing enemies from spawning while they fish.
  • Underground Monkey: Debatably the most prominent one, with it literally being the Desert Scourge except in the Sulphuric Ocean. This is downplayed as the fight plays out pretty uniquely in comparison.

    Calamitas 
https://static.tvtropes.org/pmwiki/pub/images/clam_4.png

The brimstone-wielding witch that serves as The Dragon to Yharim...or so it would seem. In reality, this Calamitas is merely a clone created by Yharim in a secret attempt to create an unwaveringly loyal backup plan in case she rebelled. However, after Calamitas found out about the secret project through the soul of one of the deceased mages who worked on it, she subsequently betrayed him and let the clone escape, allowing it to aimlessly wander the land and do what it was made to - fight. Gains a stat boost after Providence is slain.

Calamitas drops a number of useful weapons and accessories based off of her, and drops Bloodstone after Providence is beaten.

Her true form is Supreme Calamitas, one of the last bosses in the mod and magnitudes harder in difficulty.


  • Actually a Doombot: Regular Calamitas is just a clone. Supreme Calamitas is the real deal.
    Calamitas Doppelganger (Lore item): You are indeed stronger than I thought. Though the bloody inferno still lingers, observing your progress...
  • I Am Not Left-Handed: After you deplete her first health bar, she gets a second one, summons her brothers, and mocks you for underestimating her. To emphasize this, the Boss 2 theme from the vanilla game plays during Phase 1, before switching to Raw, Unfiltered Calamity after she enters Phase 2.
  • Art Evolution: She and her brothers were formerly recolors of The Twins. In her case, she was one of Retinazer. Now, she resembles a flaming wood-like eyeball. She recieved another minor one later on, which made her fire more polished and added a more distinguishable difference for her second phase.
  • Attack Drone: Can summon swarms of Life Seekers at certain HP intervals which chase players while firing lasers. However, in Expert and above she both spawns these and respawns her brothers.
  • Beam Spam: She spams deadly lasers that each split into 3 more lasers, which in turn home in on the player. Like Retinazer, her rate of fire skyrockets as she loses health.
  • Evil Brit: Her voice actress for her appearances in DM DOKURO's videos has a British accent.
  • Flunky Boss: She can summon swarms of Life Seekers and her brothers Catastrophe and Cataclysm to assist her during her second phase (more clones of them several times in harder difficulties), the former of which charges and spits fireballs and the latter of which charges and breathes fire. She also summons rings of Soul Seekers to protect her when at half health.
  • Fighting a Shadow: Turns out this Calamitas is just a watered down clone of the original.
  • Foreshadowing: How could she summon two Catastrophes and Cataclysms at once in Deathmode? They're clones, just like herselfnote .
  • Hoist by His Own Petard: The secret project Yharim started in order to clone Calamitas in case of her betrayal ended up alerting her to his scheming and kick-starting the betrayal in question.
  • Homing Projectile: Shoots splitting, homing lasers.
  • Leitmotif: Raw, Unfiltered Calamity.
  • Mascot Mook: Well, more than a Mook, really, but she is featured heavily in the mod's logo and, to an extent, its name.
  • Names to Run Away from Really Fast: Her name means "disaster" in Latin, as well as bears resemblance to the English word Calamity.
  • Orbiting Particle Shield: Pulls this off by summoning a rotating ring of Soul Seekers at half health, which soak up hits for her while firing projectiles of their own.
  • Playing with Fire: Launches exploding fireballs in her second phase.
  • Power at a Price: Her lore item increases your minion slots but lowers your max HP.
  • Red Eyes, Take Warning: She IS the red eye.
  • Reprise Medley: Her Leitmotif reuses some melodies from nearly every boss that came before hernote , along with her original Leitmotif.
  • Secret Weapon: Was designed to be one of sorts, in case of Calamitas' betrayal.
  • Shielded Core Boss: Takes Scratch Damage from everything until her brothers are destroyed. While this is a lesser example, the ring of Soul Seekers she summons at low health brings this to mind.
  • Took a Level in Badass: Stats are increased when Providence is killed.
  • Tron Lines: Sports pulsing red ones in her second form.
  • Turns Red: When you take down her first phase, she berates you for underestimating her, summons her 2 brothers and
begins lobbing deadly fireballs. Bonus points for actually pulsing red in her second phase.

    The Siren and The Leviathan 

https://static.tvtropes.org/pmwiki/pub/images/320px_siren_and_leviathan.png
The ocean depths are trembling...

The Leviathan is a massive angler fish who once terrorized the ocean depths to its heart's content before becoming bloated and old, only surviving thanks to the aid of The Siren, a mysterious sea creature that was formerly the subject of its contempt. Influenced by the Siren's kindness, the Leviathan accompanied her to the surface and slowly regained her former strength with the help of the Siren's care and companionship. As the Siren lures fishermen to her friend through her hypnotic and illusionary powers, the Leviathan now only surfaces to devour all who dare disturb it, or those foolish enough to fall for the Siren's tricks.

The Siren, on the other hand, was actually a siren child named Nahlyn born to a free-floating ocean city, outcast for her frailty and raised by a foster parent. Growing to despise the city's brutal and corrupt policies, she was soon violently orphaned, captured, and forced to serve this so-called cult - but secretly plotted her escape. Tasked with guarding the legendary trident Atlantis many years later, the timely attack of the Leviathan granted her the opportunity needed to claim Atlantis, destroy the city with its power, and escape her prison. Crediting the Leviathan for aiding in her escape, she vowed to assist the massive creature in whatever way she could.

They are intended to be fought after Plantera and before the Golem, but can theoretically be fought at any point in the game due to the way they spawn.note 

The Leviathan drops aquatic-themed weapons and accessories, and the Siren (both before and after activation) can drop some very useful acessories. Notably, if you beat it before Plantera, you will get an item which can be combined with one of Plantera's drops to craft any one of the Leviathan's own drops.


  • An Ice Person: The Siren can fire icy mist that freezes players.
  • Alluring Anglerfish: A giant-scale one with a mermaid lure.
  • Animal Nemesis: Was this for the divers and fishermen of the area it had moved by, with folkore and myths being spread about the Siren in particular.
  • Art Evolution: The Leviathan goes from more curved and tuskless to a more ferocious, bumpy look. A planned resprite may also give it a more streamlined, menacing appearance that does away with its missing back half.
    • Played up more with the lure; starting out as a recolor of a sprite, then becoming its own thing albeit rather plain, to a gorgeously designed and detailed siren. Another resprite gave it a thinner, more polished look.
  • Autobots, Rock Out!: “Forbidden Lullaby” amps up the heavy metal after gradually building up in intensity from “Siren’s Call” and “Siren’s War Cry”.
  • Battle in the Rain: A storm starts when the Lure spawns.
  • Barbie Doll Anatomy: For the Siren, at least.
  • Badass Adorable: The Siren is on the cute side of the monster spectrum, and can easily send you packing if you aren’t prepared.
  • Bait-and-Switch Boss: A bit literally in this case. Different than the norm however is that both are fought at the same time.
  • Bizarre Sexual Dimorphism: They minions it summons are apparently the males of its species.
  • Blade on a Stick: The Siren wields Atlantis, a legendary trident that grants her control over water. After felling the Siren and Leviathan, Atlantis is one of their possible drops.
  • Body Horror: The body we see now is only half of the creature, having split its back half off by using a falling cliff.
  • Bonus Boss: Downplayed. While it can technically be fought at any point in the game, it still has an "order" in that it should be fought before Astrum Aureus, Astrum Deus and the Golem, but it doesn't need to be fought at any time to advance forward like the others.
  • Bullfight Boss: The Leviathan likes to charge into the player a lot, dealing tons of damage.
  • Cheerful Child: Delve within the Abyss, and you can gain the Strange Orb. The item in question summons the adorable Young Siren. D'awww!
  • Confusion Fu: The Lure is already versatile, but with the attacks the Leviathan has as well, it’s hard to predict what they’re going to use next.
  • Cute Monster Girl: Compared to the rest of the cast, the siren lure is downright gorgeous with a nicely detailed sprite to help.
  • Cuteness Proximity: Lampshaded by the Young Siren's Buff tooltip, calling it "Small and Cute."
  • Dark Action Girl: The Siren is, rather obviously, female and is ready to kick the player’s ass when they start the fight.
  • Death Is Cheap: The Siren can be killed off and later be summoned, now on your side, by using the Heart of the Elements, Siren's Heart or Strange Orb.
  • Decapitation Presentation: Uniquely, the Leviathan’s trophy is the only one to actually be a head; the Siren’s.
  • Determinator: Being on the brink of starvation and death by old age didn't stop the Leviathan from capitalizing on the second wind given to her by the Siren. On the Siren's side, Nahlyn endured years of unwilling servitude at the siren cult and never gave up on trying to escape.
  • Dishing Out Dirt: The Leviathan spits out massive boulders to hit the player with.
  • The Dreaded: Ominous legends would start circulating around the area due to the presence of the Siren and Leviathan.
  • Dual Boss: The fight consists of the Leviathan herself and her Siren. Both must be killed for loot.
  • Early-Bird Boss: Meant to be fought by Plantera, but as it can be fought at any time, it can show up as early as the start of the game. This can also potentially be an Inverted Trope because of said factor, possibly being able to be fought after the Devourer of Gods or higher.
  • Easter Egg: Getting inflicted with the Wet debuff (from the Siren's water lances) actually weakens the bosses' attacks, making the Leviathan's meteors do slightly less damage and slightly reducing the velocity of the Siren's projectiles.
  • Empathic Environment: Beyond the aforementioned rain, the background turns pitch black once the Leviathan spawns.
  • Expy: Of Lurerre the Abysroid, both being hulking aquatic behemoths with a lure in the shape of a mermaid. This is agiven, as the lure, prior to an update, was a recolor with some tweaks.
  • Face Framed in Shadow: The top half of Siren’s face was hidden in her old sprite, with only her eyes visible.
  • Fan Disservice: An attractive mermaid acting as bait for a giant angler fish-like abomination.
  • Female Monster Surprise: While the Siren is rather obviously female, what isn't as obvious is that the Leviathan also is. Truth in Television, as female angler fish are far larger and deadlier than the practically helpless males.
  • Flunky Boss: During the fight, Paraseas and Aquatic Aberrations will spawn and attempt to attack you.
  • Flying Broomstick: Well, possibly. The Siren's capable of flying and is often seen riding on top of her trident.
  • Flying Seafood Special: The Siren can fly around above the surface and the Leviathan can also spawn above the seas and chase you without even needing to be in the water. More unusual is the Leviathan capable of moving above the water.
  • Four-Element Ensemble: The Siren is part of this with the Sand Elemental, Cloud Elemental and Brimstone Elemental when the accessory Heart of the Elements is equipped, representing water.
  • Fragile Speedster: Not very tanky, but the Siren is quite quick, and her attacks come very fast.
  • Full-Frontal Assault: Just like the other Elementals, the Siren lacks clothing, but also has Barbie Doll Anatomy.
  • Glass Cannon: The Siren isn’t too bulky, but is very versatile and hard hitting with its attacks.
  • Glowing Eyes of Doom: The Siren appears to have this, even in some older sprites.
  • Genius Bruiser: They both have signs of this. The Leviathan in particular for seemingly being just an animal is capable of forming strategies with the Siren and comes in when it’s aware trouble is starting to rise.
  • Horned Humanoid: The Siren has orange horns on the sides of her head.
  • Human Head on the Wall: Well, as close as it can get given the context, but the Siren's decapitated head trophy.
  • Interspecies Friendship: A Mermaid and a giant Anglerfish. A little downplayed, as they both are aquatic beings.
  • It Can Think: The Lure is not actually an extension of the Leviathan, but a separate living entity that had helped the Leviathan survive by bringing it corpses of fishermen.
    • The Leviathan itself shows signs of this as well, being able to form a mutual bond between itself and the Siren, as well as forming a strategy with her.
  • Jerk with a Heart of Gold: The Siren may be luring people to their unwitting doom, but it does care a lot for its friend, the Leviathan. And if the lore is any indication, the Leviathan cares for its savior and partner too.
  • Karma Houdini: Given that it’s possible that they won’t even be fought during the game, they can get away with sending fishermen and divers to their watery graves.
  • Kill One, Others Get Stronger: Defeat one first, and the other will enrage and grow stronger. In Death Mode, all of
  • Leitmotif: "Siren's Call" for the ???, "Siren's War Cry" for the Siren, & "Forbidden Lullaby" for the Leviathan, starting out with a somewhat somber melody that gradually gets more and more rocking.
  • Lightning Bruiser: Once it's below half health, the Leviathan can hurl itself at you at alarming speeds.
    • The Siren can be this as well while the ice shield is up, especially in Revengeance mode where she attacks more aggressively and uses the Leviathan as a meat shield.
  • Make Me Wanna Shout: The Siren, rather obviously, uses quite a few sound attacks, like treble clefs.
  • Making a Splash: Siren’s very capable of doing this with attacks like bubbles and water spears.
  • Mighty Glacier: The Leviathan by herself is really tanky with anywhere between 70,000 to 300,000 HP depending on difficulty and hits like a runaway freight train, but she barely moves vertically.
  • My Name Is ???: The Siren’s name at first is three question marks.
  • Off With Her Head!: The Siren is on the recieving end of this, given the trophy is her head.
  • Our Mermaids Are Different: They're the willing lures of giant monstrous anglerfish, for one.
  • Palette Swap: The Siren was formerly this for Lurerre the Abysroid’s lure with some touch ups, but it is now averted as it has gotten two sprite redos.
  • The Power of Friendship: A recurring theme revolving around the Siren:
    • What’s the name of the item that allows you access to a Super Mode? Siren’s Heart.
    • How about the Young Siren that helps provide light upon being summoned?
    • The best example would be the rare drop known as The Community, described as "The heart of the Terraria community", and is one of the best items in the game.
  • Ramming Always Works: The Leviathan will do this every now and then. The Siren will also attempt to ram players at low health.
  • Rare Random Drop: The Siren has a 1% chance to drop an accessory called The Community on Revengeance+, which can be boosted to 5% if you fight her with the Defiled Rune active. Said accessory, however, is extremely powerful, providing a myriad of bonuses that scales as the player progresses through the game.
  • Regenerating Shields, Static Health: The Siren has an ice shield that must be broken before you damage it; it can regain the shield if enough time passes. In Revengeance and above, the shield blocks piercing projectiles.
  • Revenge: There’s implication’s this is Siren’s driving motivation, given that she’s leading humans to their deaths and the backstory for the Leviathan took place after the Siren and the other Elementals were forgotten and as a result weakened.
  • Ridiculously Cute Critter: The Leviathan pet you can get at the end of the game. Interestingly, it resembles its older sprite.
  • Schmuck Bait: The Siren initially appears as the harmless "???". Kill it, and the Siren will immediately attack you. It gets even worse in Death Mode, where both the Siren and the Leviathan will immediately attack together.
    • Also worth noting is that you can find the Siren Lure anytime, even right when you start the game. Any new player that kills it is going to be in for a nasty surprise...
  • Sirens Are Mermaids: The Siren lure sings, trying to bring in fishermen to be devoured by the Leviathan while having the shape of a Mermaid.
  • Slime Girl: Implied when the Siren is summoned by the Heart of the Elements, where she is a lot more blue and translucent than before.
  • Standard Status Effects: The Siren can inflict Confusion with its treble clefs, as well as Glacial State with the icy mist, immobilizing and halving the defense of a target.
  • Start of Darkness: Killing Nahlyn's mother and forcing her to serve the city she hated was NOT a good idea.
  • Stationary Boss: Downplayed, as it will still chase after you if you move horizontally, but it doesn't move nearly as much as other bosses.
  • Super Mode: You can actually get one by obtaining the Siren’s Heart, allowing you to turn into the Siren herself.
  • Super-Persistent Predator: The Leviathan just refuses to die, surviving near starvation and old age while continuing to fight onwards.
  • Suspiciously Stealthy Predator: Somehow capable of pulling this off as well as the above trope, completely undetected until the Siren’s at low health.
  • The Dog Bites Back: As punishment for her disdain towards her city, the people of her home killed Nahlyn's foster mother and forced her into servitude for years. Come the Leviathan's attack, and Nahlyn stole the city's legendary weapon, used it to lay waste to the place, and then escaped after leaving the city to the Leviathan.
  • Theme Music Powerup: At first, the Siren's theme is serene and unsuspecting. Then, when she begins her attack, the song picks up and gains intensity. And when the Leviathan itself finally shows up, the song descends into full metal territory.
  • True Companions: The Siren and Leviathan owe each other their lives, and as such always have each others' backs. Although the Siren does seem to show more kindness towards the Leviathan than the other way around.
  • Used to Be a Sweet Kid: The Young Siren summoned from the Strange Orb implies this, given all it does is hang around casting a light. The lore only makes this more obvious - Nahlyn started as a normal girl, before being orphaned and forced to serve a ruthless cult.
  • Villainous Friendship: The Siren and Leviathan genuinely care for each other and will assist each other in combat without hesitation. Justified, as the Leviathan indirectly freed the Siren from her unwilling imprisonment, and the Siren returned the favor right afterwards.
  • Villain Song: Downplayed, as the Siren never really says a word, but it’s implied the Siren is the one that’s singing throughout all three phases.
  • Wake-Up Call Boss: By virtue of the fact that it can be fought at any time, it can potentially be fought before King Slime or the Eye of Cthulhu.
  • Yellow Eyes of Sneakiness: Both of them have it and are associated with stealth and trickery.

    Astrum Aureus 
https://static.tvtropes.org/pmwiki/pub/images/astrum_aureus.png
A star has fallen from the heavens!

A colossal, spider-like machine designed by Draedon to collect samples from the Astral Infection. However, it eventually succumbed to the disease despite its inorganic nature. Seeing this as proof that the Infection could infect machinery, Draedon deemed the machine obselete and abandoned it in the Astral Infection, where it awakens only to fight off external threats. Killing it spawns an Astral Meteor, but you need to kill Astrum Deus first in order to mine the Astral Ore contained within it.

Drops an abundance of Stardust and Fallen Stars, as well as consumables called Aureus Cells. After Moon Lord is defeated in Revengeance, it becomes substantially more powerful in exchange for dropping large amounts of the 4 Celestial Fragments and a unique mount.


  • Action Bomb: Summons Aureus Spawn, floating enemies that teleport around. While initially passive and able to reduce all damage to 1 (2 on crit), if sufficiently damaged they'll chase you and explode violently. The amount of damage required to trigger decreases as the difficulty increases (12 in Normal, 7 in Expert and Revengeance, and 2 in Death).
  • A.I. Is a Crapshoot: Draedon didn't expect the Astral virus to be powerful enough to infect a mechanical being, but it was. Not that he was upset, though - he considered it an overall success.
  • Art Evolution: It was formerly a giant, purple slime called the Astrageldon Slime. Now, it's a biomechanical, flaming spider.
  • Beam Spam: Rapidly launches shotgun blasts of fireballs and radial bursts of homing missiles to bombard players.
  • Big Creepy-Crawlies: A giant mechanical spider-crab monster infected with a cosmic pathogen.
  • Expy: Of Security Robot B.O.X. from Metroid Fusion, both being giant quadrupedal cyborgs that became infected by space-borne diseases. Even their methods of battle vaguely resemble each other.
  • Gemstone Assault: Can launch radial bursts of astral crystals, which will travel a distance before attempting to track down players.
  • Homing Projectile: The radial spreads of crystals that it fires will start seeking out players after travelling a certain distance.
  • Leitmotif: "Interstellar Stomper".
  • Load-Bearing Boss: Subverted. Its lore item specifically states that killing Aureus won't do anything to stop the infection. In fact, like the Hive Mind, its death spawning another Astral Meteor means that killing it actually speeds up the infection.
  • Meaningful Name: Astrum Aureus translates to "Golden Star" in Latin. While it is by no means golden, its name also brings Staphylococcus Aureus to mind, fitting for a being whose death kick-starts an Astral Infection.
  • Mighty Glacier: Aureus has above-average HP and deals a lot of damage with each attack, but it's fairly slow and can't fly.
  • Playing with Fire: It launches directed spreads of fireballs and flaming, homing crystals. Its back is also alight with red flames, which will occasionally stop burning when it rests.
    • In addition, several of its attacks inflict God Slayer Inferno.
  • Took a Level in Badass: If you are playing in Revengeance mode, it becomes absurdly powerful post-Moon Lord in exchange for dropping more items, most notably massive quantities of the Celestial Fragments.
  • Teleport Spam: It will frequently vanish and reappear from a different angle to get the jump on players.

    Astrum Deus 

https://static.tvtropes.org/pmwiki/pub/images/astrum_deus_76.png
May the stars guide your way.

Once an astronomical, legendary god-serpent of the stars, Astrum Deus met an untimely demise at the jaws of the Devourer of Gods under Yharim's orders. However, the power from its ravaged body fell from space and blessed several worms on the planet, in hopes that they could grow as vessels for the Star God to be reborn through. Formerly the biggest vessel of the Astral Infection, the same remains that blessed Terraria's worms in a bid for resurrection also brought the space-born plague to the surface after the serpent was killed.

They are meant to be fought at night after Astrum Aureus. Killing them will allow the player to mine Astral Ore from Astral Meteors.

In addition to releasing the aforementioned lock on Astral Ore, making Astral Infection enemies start dropping more items, and allowing the Astral Chest to be opened, it also drops some star-themed equipment for your troubles, including the Starlight Fuel Cell in Revengeance which permanently decreases your Adrenaline charging time. It also has a rare chance to drop the Quasar and the Hide of Astrum Deus, the rare variants of the Radiant Star and the Astral Bulwark respectively.


  • Art Evolution: From a rocky, predominantly gold-and-purple serpent to a metallic silver one with blue-and-red accents, to fit with the revamp of the Astral Biome.
  • Beam Spam: Much like Destroyer, it fires off lasers like a machine gun.
  • Bilingual Bonus: Its name means "Star God" in Latin.
  • Celestial Body: It was once a divine serpent of incomprehensible proportions who was the light source of the stars themselves.
  • Cruel and Unusual Death: Suffered from one, courtesy of the Devourer of Gods. The Devourer tore open the larger divine serpent’s gut and burrowed in, feasting on its body and killing it from the inside out before crushing its husk to pieces between its coils and scattering the remains to the cold void of space.
  • Damage Over Time: Contact with it inflicts God Slayer Inferno, which deals harsh damage over time.
  • Eldritch Abomination: Back when it was a full-fledged star god, its very nature was unimaginable, to the point that its presence in reality could only be glimpsed through the countless stars its body birthed.
  • Flunky Boss: Like Destroyer, it will spam Astral Probes as it loses HP.
  • Grenade Spam: One of the worms will always have a layer of orbiting probes that spew Astral Mines, stationary orbs that linger in the air before exploding. The frequency of the mine-laying increases with each worm killed.
  • Heavily Armored Mook: For a worm boss, Astrum Deus has abnormally high Defense, greatly lowering the damage output of any weapon that hits it. However, it is still vulnerable to piercing weapons unlike other worms.
  • How the Mighty Have Fallen: Astrum Deus was a fallen god just like the Brimstone Elemental, except it had been even more powerful than the Elementals before its fall; it was an incomprehensible god of the stars who was brutally consumed by the Devourer of Gods. It has since been reduced to the Wolfpack Boss that you encounter in-game.
  • Leitmotif: "Pest of the Cosmos".
  • Meaningful Name: Its name translates into "Star God", which is exactly what it is. Or at least, what it used to be.
  • Pieces of God: The Wolfpack Boss that you fight are worms that were empowered by the star god's astral power, so that they may grow and allow Astrum Deus to one day return to the cosmos.
  • Reincarnation: Even after its death, Astrum Deus' corpse held power; fragments of its body would one day fall to the planet and choose a successor to the god of the stars.
  • Segmented Serpent: Like the other Worm bosses. However, Astrum Deus stands out for its abnormally high defense.
  • Shielded Core Boss: The main, most powerful worm is invisible and invulnerable until its 10 smaller counterparts have been destroyed.
  • Tulpa: It was a god who was brought into existence by humanity's collective faith.
  • Turns Red: The more worms you take down, the faster the worm with the orbiting probes will churn out Astral Mines.
  • Wolfpack Boss: You have to fight 10 of them at once in the first phase.

    The Plaguebringer Goliath 
https://static.tvtropes.org/pmwiki/pub/images/4136c2e3_4414_409e_ab21_69505bfb59d4.gif

One of the bio-weapons that was a result of an experiment that Yharim conducted to weaponize the Queen Bees. However, unbeknownst to him, one of his head scientists had added a weapon that the Tyrant had deemed too deadly for use: Nanomachines that would cause victims to rot from the inside out while still being kept alive. The plague spread through the entire jungle, infecting entire hives, and rather than destroy the plagued bees Yharim instead made them his living weapons, turning them into some of his deadliest servants: the dreaded Plaguebringers. Meant to be fought in the Jungle after Golem.

Killing it rewards you with various powerful plague-themed weaponry and equipment.


  • Action Bomb: In Revengeance, it can summon Plague Mines that chase players before exploding. It can also fire homing missiles that can be fortunately shot down before they hit you.
  • Artificial Zombie: A combination of this and Plague Zombie, being bees that have been infected by a nano-virus that turns the poor creature into a rotting carcass enslaved to Yharim’s will before being fitted with missile pods and armor plating. Oh, and they can spread their horrible condition to others too.
  • Art Evolution: Twice. At first rather plain, then a bit more detailed as a Queen Bee recolor, then a more sleek design with fang-like mandibles.
  • Bee Afraid
  • Big Creepy-Crawlies: Was originally a giant bee like the Queen Bee. It has since been transformed into an undead cyborg monstrosity.
  • Body Horror: Whatever parts of the Goliath's body that are not mechanical are rotted away from Yharim's virus. It’s pretty obvious that the things you fight are no longer alive by this stage. Hopefully.
  • Cyborg: Before their infection, Yharim had them augmented with missile launchers and armor plating as a project to weaponize the Queen Bees. Although it looks like they’re more machine than bee at this point, as their liquified remnants are dripping out of their armor.
  • Death from Above: When it says "PLAGUE NUKE BARRAGE ARMED, PREPARING FOR LAUNCH!!!", it will gain the ability to charge around above the player, raining down plague rockets in the process.
  • Degraded Boss: Right after Golem is killed, weaker versions of itself simply called Plaguebringers can start showing up in the jungle, identifiable by their smaller size and green eyes as opposed to the Goliath's red.
  • The Dreaded: Feared both for their incredible destructive power and the murderous plague they spread in their wake.
  • Empathic Environment: It will tint the screen greenish when summoned.
  • Flunky Boss: Summons Plague Chargers constantly. In Revengeance Mode, it can spawn Plaguebringers as well.
  • King Mook: Serves as one for the Plaguebringers, down to their sprites being almost identical.
  • Leitmotif: "Fly of Beelzebub".
  • Lightning Bruiser: It's extremely quick, has a surprising amount of bulk, and hits like a truck. That's not even getting into its arsenal of explosive artillery...
  • Macross Missile Massacre: Constantly unloads enormous fusillades of stingers and rockets aimed at targets, especially when it charges. It can also fire storms of destructible, homing rockets at players.
  • More Dakka: Besides firing volumes of rockets, one of its other attacks is to spray plagued stingers at the target. In Expert mode, these explode too.
  • Mechanical Monster: An abomination made of rotted flesh and metal that functions as a mindless killing machine.
  • Names to Run Away from Really Fast
  • Ninja Pirate Zombie Robot: A giant rotting undead robot bee armed to the teeth with military-grade weaponry and capable of spreading a deadly plague wherever it goes.
  • No Indoor Voice: Given all of its lines are in all caps and have a minimum of two exclamation points.
  • Our Zombies Are Different: Technically, the Goliath isn't even alive: it's essentially an dead, diseased, rotting bee that only operates due to being composed of mostly machinery.
  • Palette Swap: Of the standard Plaguebringers. Besides being much bigger and having red eyes instead of green, they're almost identical.
  • Person of Mass Destruction: It is described as being able to easily raze an entire city to the ground through its artillery. And due to the deadly plague it spreads, anything that isn't blown up will be turned into an apocalyptic wasteland.
  • Plague Master: Hey, it's in the name.
  • Poisonous Person: By extension of the above trope.
  • Power at a Price: Holding its lore item increases wing time but lowers life regeneration.
  • Rare Random Drop: Has a 1% chance to drop the legendary dagger Malachite on Revengeance+, which can be boosted to 5% if you fight it with the Defiled Rune active. Said dagger is a potent throwing weapon that can both rapid-fire explosive kunai or shoot piercing knives.
  • Red Eyes, Take Warning
  • Sickly Green Glow: A recurring theme with the Plaguebringers, but the Goliath takes this further by tinting the screen green-ish when active.
  • Turns Red: When below half health, it will activate the Plague Nuke Barrage, which allows it to rain down large quantities of missiles from above the player. Averted in Death Mode, where the attack is active at the start of the fight.
    • In Expert and above, its projectile damage, defense, and projectile spam will ramp up as it loses HP.
  • Weaksauce Weakness: Despite being a biomechanical zombie, the Plaguebringer Goliath is still classified as a bee enemy, and as such can have its contact damage halved through the use of the Honey Dew accessory or its upgrades.

    The Ravager 
https://static.tvtropes.org/pmwiki/pub/images/ravager_8.PNG
An ancient automaton roams the land...
A horrific, mindless amalgamate created from countless dead bodies, the Ravager was created as a last resort against Yharim's troops by a desperate group of human survivors. Designed solely for the purpose of killing, it slaughtered its targets before doing the same with its creators - and without any purpose but to destroy, the Ravager aimlessly roams the land doing just that. Intended to be fought on the Surface after Golem. Gains an immense stat buff (and unique loot drops) after Providence is killed.

Drops various bars and cores which would have required a lot more effort to craft, along with several unique weapons and accessories. After Providence is killed, it begins dropping Bloodstone as well. Notably drops the Infernal Blood in Revengeance, which permanently boosts your Rage Mode damage.


  • A.I. Is a Crapshoot: The first thing it did after slaying the ones whom it was created to kill was turn on its creators and do the same to them. Perhaps making it's only motivation "mindless destruction" wasn't such a good idea...
  • Art Evolution: Heavily resembles a walking fortress with flaming towers now, and overall looks far more polished and coherent.
  • Beam Spam: Its body rapidly fires off rings of lasers in its second phase, and its head launches homing ones.
  • Bizarre Alien Biology: Its head can fly off and attack you once sufficiently damaged. There is also the natural blue flames on its tower-like "shoulders," as well as one of the skulls seemingly growing from beneath the other.
  • Body of Bodies: The Ravager is an abomination created from a reanimated mass of corpses.
  • Cognizant Limbs: Much like Golem, Ravager's arms can fire at you independently.
  • Damage-Sponge Boss: With its massive health pool, sturdy defenses, and multiple body parts, the Ravager can take a huge amount of punishment before going down.
  • Dem Bones: Its body is supposedly made out of unbreakable bone fortified by its dark magic. Its twin skulls are also its most prominent feature.
  • Detachment Combat: When its head loses all its HP, it starts flying around, trying to ram players and fire rockets.
  • Dishing Out Dirt: Whenever it stomps, it can cause giant damaging pillars of rock to appear. These will quickly launch out of the ground and attempt to land on players.
  • Eldritch Abomination: A massive, grotesque monster that looks like an amalgamated fusion of flesh, bones, and rock, with 2 skulls and purple flames erupting from its "shoulders."
  • Expy: Its general 'headless' design, otherwordly design and traits, and the placement of its twin skulls could bring Sachiel to mind.
  • Flesh Golem: It's a Living Weapon made out of fused corpses and weapons. It even has a similar AI as the Golem from the original game.
  • Gameplay and Story Segregation: In its lore, it is stated to have the "regenerative durability of a fortress". While it may be a Damage-Sponge Boss in game, it has no healing abilities whatsoever.
  • Glowing Eyes of Doom: One red and one blue, in fact.
  • Gravity Screw: Upon having its limbs taken care of, the Ravager will permanently inflict all players with Weak Petrification, which severely limits the players' mobility by cutting flight time by 90%, disabling mounts, disabling any additional jumps, and removing all jump height boosts.
  • Hoist by His Own Petard: The first thing it did after its creation was kill all of the men who threatened its creators. The second was to kill said creators as well.
  • Homing Projectile: It can launch giant missiles that home in on players before exploding for enormous amounts of damage. Its head also launches smaller, red flares that have a weak tracking property.
  • Leitmotif: "Open Frenzy".
  • Last Stand: Was designed to be this by a particularly desperate group of human survivors. Well, to give them credit, it did kill their attackers...
  • Living Weapon: It was created for the sole purpose of destruction, and it boasts enough power and weapons to single-handedly wage wars.
  • Losing Your Head: As seems to be growing common nowadays, the Ravager's head will detach and fly after you when destroyed.
  • Mighty Glacier: Ravager isn't very mobile compared to many of the other bosses (not helped by a lack of flight/teleportation abilities), but it has very high HP at the point you're supposed to fight it and deals incredibly high damage with a wide range of attacks. Not to mention that instead of running to you, it can force you to itself using its petrification and flight-nerfing powers.
    • Holding its lore item turns you into one, boosting all damage at the cost of wing time.
  • Mismatched Eyes: Played with. It has two faces, one that has a single red eye and one that has a single blue eye. Played straight with its minimap icon, which is a skull with both a red and a blue eye.
  • Names to Run Away from Really Fast
  • Omnicidal Maniac: It only has one driving motivation: destroy everything in sight.
  • Our Zombies Are Different: It's essentially a weaponized mass of corpses given life by dark magic.
  • Person of Mass Destruction: It's supposedly powerful enough to wage wars all by itself, and was never captured or defeated by either Yharim's forces or his opponents.
  • Playing with Fire: Periodically summons pillars of blue flame around the player, which deal high contact damage and lob bouncing fireballs. In addition, its body can launch bouncing fireballs like Golem.
  • Red Eyes, Take Warning: Well, one of them anyway.
  • Rocket Punch: Like Golem, its fists can extend to punch you.
  • Shielded Core Boss: Ravager's main body is invulnerable until all of its body parts are destroyed.
  • Taken for Granite: Implied with the Weak Petrification debuff it hammers you with in its second phase.
    • It can literally petrify you if you run too far away from it.
  • The Power of Blood: Played with. While it doesn't use this itself, all of its items that aren't Cores or Bars (the Hematemesis, Bloodflare Core, Blood Pact, and Flesh Totem) seem to use blood as a central theme. The item obtainable from fusing all of Ravager's accessories together is even called the Core of the Blood God.
  • Took a Level in Badass: Ravager gains a truly enormous stat boost after Providence is killed, multiplying its health by almost 15 times. However, it also drops loot that it didn't before.
    • On a more meta level, the Ravager used to be just a stronger Golem clone with a few more attacks (that were developed from Golem itself). Now, it is far more powerful, possessing higher damage output, a more diverse and unique moveset, and the ability to uniquely inflict a debuff that nearly completely neuters your flight power.
  • Turns Red: If the player gets underneath it, it will receive a large speed boost and start firing projectiles more aggressively.
  • You Will Not Evade Me: If the player strays too far away from the Ravager, they will be frequently turned into stone, impeding them from moving further away.

Post-Moon Lord Bosses

    The Profaned Guardians 
https://static.tvtropes.org/pmwiki/pub/images/profaned_guardians_0.png
The Profaned Flame blazes fiercely!note 

The eternal servants of the Profaned Goddess, formed from the souls of the worshippers that devoted their lives to protecting their God. So long as Providence is alive, they live eternally. They are meant to be the first boss you fight after Moon Lord, and can only be fought in the Daytime Hallow/Underworld.

They don't drop anything except a Profaned Core, which is used to summon Providence herself.


  • Art Evolution: They have become far more polished and organic-looking, with each guardian receiving its own unique sprite.
  • Ascended to a Higher Plane of Existence: Having been devoted to Providence for so long, they ascend to become her eternal guardians.
  • Degraded Boss: They are summoned by Providence herself as minions during her boss fight.
  • Heel–Face Turn: Smaller versions of the Guardians can be summoned as helpers by the Profaned Soul Artifact obtainable after Providence.
  • Homing Projectile: The Crystal Guardian can fire bursts of orange beams that home in on the player, dealing a surprisingly high amount of damage. These beams, however, will dissipate after travelling far enough.
  • Javelin Thrower: More like javelin shooter - the Main and Rock Guardians use radial bursts of accelerating fire spears to attack. The former notably fires a lot more of them in a single sitting.
  • Leitmotif: "Unholy Ambush".
  • Lightning Bruiser: The Main Guardian, having the most health, highest durability, and highest damage output, not to mention the widest variety of attacks.
  • Loophole Abuse: Much like one of their master's attacks, the Crystal Guardian's flares count as negative healing and will actually instantly decrease their target's health regardless of Mercy Invincibility, defense, or damage reduction. While its version of the attack is far weaker and short-ranged, it serves as an introduction to Providence's version, which is far stronger and liberally spammed.
  • Mini-Boss: Usually seen as this, since they're not particularly strong and only drop the item used to summon their master.
  • Oxymoronic Being: They seem to be made partially of wood, despite the rest of their bodies being flaming rock and them using fire as their main power.
  • Playing with Fire: They all attack using fire.
  • Power Crystal: The Crystal Guardian has numerous purple crystals on its body.
  • Rock Monster: Much like their master, their bodies are mostly made of rock.
  • Resurrective Immortality: If killed, they will just reform from Providence later. Yharim has stated that he had to kill the Guardians countless times in his search for Providence.
  • Shielded Core Boss: The main and most powerful Guardian is invulnerable until the other two are killed.
  • Spikes of Doom: The Main Guardian has a prominent molten spike on its front.
  • Stone Wall: The Rock Guardian, having the most durability of the two lesser guardians but the least attack power.
  • Support Party Member: The Crystal Guardian, who has the worst stats and sits in the backlines while firing homing flares.
  • Turns Red: The main Guardian gains access to more and more attacks as it loses HP, going from simply firing spears to launching massive fireballs and leaving flame trails wherever it goes.
    • In addition, taking any of the Guardians out of the Hallow/Underworld will cause them to start taking Scratch Damage from all attacks.
  • Wolfpack Boss: There are 3 Profaned Guardians that must be killed. The main, offense-oriented one charges at players while spraying flaming spears, the second defense-oriented one who circles the main one while firing spears, and the third support-oriented one that heals the others fires homing blasts from a distance.
  • The Worf Effect: In their backstory, they fought Yharim to stop his influence and actually managed to push him to the brink of defeat. However, he promptly summoned the Devourer of Gods, who delivered a Curb-Stomp Battle to the Guardians.

    The Bumblebirb 
https://static.tvtropes.org/pmwiki/pub/images/bumblebirb_5.png

Odd creatures created by Yharim as a failed experiment to create clones of Yharon's species. They were left to their own devices in the Jungle, where they wander aimlessly and attack anything that poses a threat to the Jungle Tyrant. They can reproduce with themselves to create new Bumblebirbs, however they have a hormone that shuts down their reproduction if there are too many Bumblebirbs nearby.

Bumblebirbs drop several weapons and Effulgent Feathers, which are primarily used to make Silva Armor and craft the Dragon Egg to summon Yharon. It also has a rare chance to drop the Swordsplosion, the rare variant of the Ark of the Elements. In Revengeance, it also drops the Red Lightning Container to permanently buff your Rage Mode damage.


  • Extra Eyes: It's not very obvious, but the Bumblebirb actually has four eyes much like the being they were cloned from.
  • Feather Flechettes: While flying, it can sometimes shed a burst of its own electrified, knife-like feathers. These will soon redirect themselves and home in on players.
  • Flawed Prototype: A failed attempt to create more of Yharon's species resulted in these Bumblebirbs.
  • Flechette Storm: Capable of doing a smaller-scale version of this by launching its feathers.
  • Fluffy the Terrible: Is an efficient killer and a dangerous boss, but its ridiculous name makes it hard to take seriously.
  • Genetic Engineering Is the New Nuke: Was an attempt at making a bio-engineered killing machine. Yharim cites the experience as a display of "our faulted arrogance over life".
  • Homing Projectile: The electrified feathers it launches will redirect towards and fire themselves at players.
  • Leitmotif: "Murderswarm".
  • Lightning Bruiser: Hits like a runaway bullet train and moves just as fast. Its HP, while nothing obscene, is still passable.
  • Mini-Boss: Usually regarded as this, mostly due to having a very simple AI compared to most bosses. However, even with its below-average difficulty, it's still not one to be underestimated.
  • Self-Duplication: All Bumblebirbs have the ability to do this. The only thing stopping them from overpopulating the Jungle is their built-in protocol that shuts down their reproductive hormones if there are too many Birbs nearby.
  • Shock and Awe: Can sometimes fire spreads of electrified feathers during flight. It also creates red electricity whenever it flaps its wings, its feathers constantly crackle with it, and it drops an item called the Red Lightning Container.
  • Unskilled, but Strong: Unlike most of the other endgame bosses which use complex bombardments of projectiles and gimmicky mechanics to screw you over, the Bumblebirb's main method of attack boils down to "run at the player and ram them". Unfortunately for the player, it has the stats to make this tactic work.
  • Wolfpack Boss: It can spawn small Bumblebirbs to attack alongside it.

    Providence, the Profaned Goddess 
https://static.tvtropes.org/pmwiki/pub/images/providence_the_profaned_god_7.png
The air is burning...

A fiery deity of light and dark, born from a clash between angels and demons long ago. Upon the moment of her conception, Providence became disgusted with the vices and virtues of the world, and made it her mission to annihilate everything and cleanse the world of all desire. However, unable to purify the world while the Devourer of Gods hunts her, she waits in the center of the sun, gathering power and awaiting the moment when she can descend upon the world and burn away everything with her purifying flame.

She is meant to be fought right after the Profaned Guardians, and like them can only be fought in the Daytime Hallow/Underworld, with her drops differing depending on where you killed her.

Providence drops many weapons which revolve around holy fire, Divine Geodes used to make Tarragon Armor among other things, and also drops the Rune of Kos, used to summon the Sentinels of the Devourer. She also has a rare chance to drop the Samurai Badge, the rare variant of the Badge of Bravery. Her death also causes Uelibloom Ore to generate in the world. In Expert and above, she drops a unique accessory depending on where she's killed (the Elysian Aegis for the Underworld, and the Elysian Wings for the Hallow). Killing her also buffs up Dungeon and Brimstone Crag enemies (along with Calamitas, Ravager and Brimstone Elemental), while allowing them to drop Phantoplasm and Bloodstone respectively.


  • Anti-Frustration Features: A Profaned Core (her summoning item) can combined with a bunch of Unholy Essence to create a special Profaned Core which has infinite uses.
  • Art Evolution: Formerly, Providence was a massive moth with red wings. Then, she was a large statue-like mass with flaming wings. Her current sprite takes this even further by giving her a more cohesive design with an actual head, pale purple crystals lining her "shoulders," and flame wings that now resembles a Daimonji.
  • Big Creepy-Crawlies: Her old design was this, instead of the mass of rock and flame she is currently. She still had some traits in some former sprites, primarily her "head" having mandible-like protrusions (which she retained in her newest sprite).
  • Blue and Orange Morality: Sees life and death as the source of all desires, both positive and negative. Therefore, she wants to create a world where nothing lives and nothing dies, which would be completely sinless to her.
  • Contractual Boss Immunity: Providence uniquely resists the damage reduction penalty that Ichor and Cursed Flames give - instead of decreasing her DR by 25%/20% respectively, both of the effects will decrease her DR by a much weaker 5%.
  • Defend Command: Occasionally Providence will retreat into her shell and increase her damage reduction to 90%, while spraying either a maelstrom of flames or a barrage of flaming spears. In both cases, dodging is your best option - although, unlike Brimstone Elemental it's still possible to do reasonable damage to her during this state.
  • Empathic Environment: Causes the area to turn orange.
  • Expy: Being a six-winged, vaguely insectoid being of fire, she bears similarities to Volcarona, which were especially evident with her older sprites. Her current sprite also somewhat resembles The Radiance, being a vaguely mothlike goddess of fire and light.
  • Fire Purifies: Her flames supposedly purify everything they touch. "Purify" meaning "reduced to an impartial ash, free of all desires and sin".
  • Flechette Storm: One of her attacks summons a swarm of flaming spears to pincushion you with. She'll both fire these spears directly and summon them around the player.
  • Flunky Boss: Although plenty powerful by herself, she can summon a group of Profaned Guardians at 35% HP.
  • Gravity Screw: She inflicts the debuff Icarus' Folly, which greatly reduces flight time.
  • Hot Wings: Her wings are entirely made of fire.
  • Invincible Minor Minion: Once below a certain amount of health, she'll summon an invincible crystal that hovers over the player for the rest of the battle, showering them with damaging crystal shards.
  • Leitmotif: "Unholy Insurgency".
  • Lightning Bruiser: She's very fast, extraordinarily bulky, and deals huge amounts of damage through her projectile spam.
  • Light Is Not Good: Primarily wields fire and light based powers, and is an Omnicidal Maniac who wants to destroy all life.
  • Loophole Abuse: She has a very particular attack that doesn't inflict damage conventionally, but instead "heals" the player by a negative amount. As a result, this attack gets to alter your health directly, completely bypassing your defense, your damage reduction, and your invincibility frames in the process.
    • On the flip side, since it doesn't count as damage, it won't interrupt your Adrenaline if you're on Rev+.
  • Omnicidal Maniac: Seeks to obliterate everything in an attempt to purify the world of both vices and virtues.
  • Oxymoronic Being: A god of both light and darkness.
    • Even her name contradicts itself: since "profaned" means desecrated or defiled, she is essentially an unholy god.
    • Her new sprite takes it even further, since she has wooden parts despite being on fire.
  • Physical God: Specifically, a fire/sun goddess of light and darkness who seeks to erase everything to cleanse the world. Her lore states that if allowed to attain her full power by absorbing the sun's energy, there would be nothing that could withstand her flames when she returned to fulfill her task. Even Yharim seems fearful of this prospect.
  • Playing with Fire / The Power of the Sun: Her main method of attack is obliterating her target with showers of holy fire blasts. She shoots volumes of fireballs, exploding flares, fireballs that explode into more fireballs, lingering fire blasts, flaming spears, fireballs that launch more fireballs...you get the point.
    • Equipping her lore item grants you this power as well, imbuing all of your projectiles with profaned fire.
  • Power Crystal: Her shoulders feature prominent purple crystals, and she has a purple gem which serves as her core. In battle, she can also summon an invincible crystal that rains down crystal shards on you.
  • Power Gives You Wings: Whenever she's in her active state, she has distinct wings made of pure flame.
  • Pure Is Not Good: She seeks to purify the world of all sin...by wiping out everything there is.
  • Rock Monster: Her body is mostly made of rock and purple crystals, intertwined with wood and veins of fire.
  • Tactical Suicide Boss: In one of her phases, she summons a number of deadly fireballs. Along with them, she summons green orbs that heal players that collect them. Averted in Deathmode, where she only uses orange flames.
  • Turns Red: If you get too far from her, she'll inflict the Holy Inferno debuff until you come back. Said debuff drains your HP at an exponentially increasing rate to ensure quick death should you refuse to get closer to her.
  • Wave Motion Gun: Once she's below a certain HP threshold, she can charge up and fire a gigantic laser beam that tracks the player a la Moon Lord. However, she will slow down while firing to compensate, although she takes significantly reduced damage while charging.

    The Polterghast 
https://static.tvtropes.org/pmwiki/pub/images/polterghast.png
Shrieks are echoing from the dungeon...

As the death toll of Yharim's reign rose, he inadvertently created a large number of vengeful spirits that clung to the world via their hatred. Attracted to the dungeon, the spirits began consuming each other in a bid for power, until the amalgamation known as the Polterghast was born. Reduced to a mindless beast, it aimlessly feeds on its brethren until it can finally take its revenge on the subject of its collective hate. It appears in the dungeon after you kill 30 Phantom Spirits.

Drops numerous spectral weapons as well as the Ectoheart in Revengeance which permanently shortens your Adrenaline charging time, and killing it also allows certain Abyss foes to start dropping items. Also drops Ruinous Souls, which are used to create gear like Bloodflare Armor.


  • Almighty Idiot: As lesser souls grew swift and elusive, the first souls to feed continued to fight and consume one another until a legion took form, lacking even the concept of predator and prey. At that point, nothing drove the amalgamation besides eternal hatred and an insatiable hunger.
  • Animated Armor: Its armor and chains are just scraps of metal animated by its power.
  • Anti-Frustration Features: After you've defeated it for the first time, killing Phantom Spirits will no longer force-summon the Polterghast. Instead, if you want to refight it, you'll have to make a Necroplasmic Beacon.
  • Big Creepy-Crawlies: Vaguely resembles a stag beetle.
  • Bonus Boss: Polterghast is the only Post-Moon Lord boss that isn't required to advance the progression of the game, but the items you get from him and his Ruinous Souls can give you a huge edge over the next couple of bosses. You also need the Bloodflare Armor if you want to make the Auric Tesla Armor in the endgame.
  • Beam Spam: Its primary means of attack in Phase 1 and 2. They alternately bounce off surfaces or home and pierce walls.
  • Cannibalism Superpower: Originally a number of separate spirits, the Polterghast came to be after the spirits turned on each other and began to consume and merge with one another.
  • Combat Tentacles: In a similar vein to Plantera, it uses damaging hooks to move itself around. Turns out it actually doesn't need them - once it loses enough health, it will detach its hooks and turn them into invincible turrets while it begins flying.
  • Damage-Sponge Boss: While it doesn't have a particularly stellar HP pool, it has damage reduction that increases as it loses HP, which makes it nigh-impossible to burst down and allowing it to actually take less damage the more injured it is. This is taken to an absolute head in its final phase, where it has a respawning clone of itself that massively reinforces its damage reduction while alive, making killing it a priority - which is easier said than done since the clone has a significant amount of HP and respawns seconds after being slain.
  • Doppelgänger Spin: As the Necroplasm, it can spawn a clone of itself that attacks just like it. While the clone has far less health and lacks Polterghast's signature obscene damage reduction, it will be respawned shortly after being killed.
  • Expy: The Polterghast, in particular its last form the Necroplasm resembles the Metroid Prime.
  • Flunky Boss: Summons invincible Phantoms in its final phase that orbit players while shooting. Once it's at low HP, it'll start spawning Happy Phantom Spirits that chase players while firing.
  • Fusion Dance: A fusion of numerous spirits into one creature.
  • He Was Right There All Along: How do you summon Polterghast before killing it once? You don't, because Polterghast summons itself after the player kills enough Phantom Spirits in the dungeon.
  • Horror Hunger: One of the only things that keeps Polterghast going is an relentless hunger for more that cannot be satisfied.
  • Implacable Man: Taken to an absolute head. It starts off taking normal damage, but as it loses health its damage resistance will slowly go up. Once it's nearing the end of its life, Polterghast will only be taking a fraction of the damage you dealt to it originallynote  - sometimes making the last quarter of its health bar tougher to whittle down than the three quarters you already took down.
  • Improvised Armor / Improvised Weapon: In order to hunt its fellow spirits more effectively, the Polterghast scraped together and animated loose fragments of metal to create its armor and chains.
  • Invincible Minor Minion: The Phantoms it spawns as the Necroplasm (one stage earlier as Necroghast in Death Mode). They are invincible and will rotate around the player, deploying spectral mines which slowly accelerate towards their target.
    • Once it becomes the Necroghast, its hooks detach and become mobile turrets. As the Necroplasm, the hooks become stationary.
  • King Mook: Seems to be one to the various spirits roaming the dungeon. Its lore reveals that it's actually a mass fusion of said spirits.
  • Leitmotif: "Feral Amalgamation".
  • Lightning Bruiser: While it normally moves at a fairly slow pace, as the Necroplasm it's capable of terrifying bursts of speed and deals immense damage on contact. In addition, it should still have a good amount of HP left on top of its significant damage resistance, not to mention being Nigh Invulnerable while its clone is alive.
  • Merger of Souls: It is an entire legion of souls that fused into a single, monstrous being.
  • Murder Into Malevolence: All of them were victims of Yharim's conquest. As spirits clinging to reality through little more than hatred, they held no loyalty to their fellow dead. Many swiftly turned on each other - souls devouring souls in an instinctual bid for power.
  • Our Ghosts Are Different: For one thing, it's a giant spectral insect-like thing with a rocky shell that fires lasers. Not to mention it's actually a fusion of innumerable spirits instead of being just one.
  • Pinball Projectile: Its shots bounce off walls.
  • Poor Communication Kills: Despite consuming its own brethren for power, it's not openly hostile to anyone except Yharim himself. Unfortunately for you, your power has approached the point of indistinguishability, and the Polterghast has become too mindless to do anything but lash out in anger.
  • Ramming Always Works: As the Necroghast, it abandons all of its projectiles and resorts to simply ramming into you. Of course, its minions will supplement some of its former projectile spam.
  • Schmuck Bait: Thinking of farming some Phantom Spirits right after Providence? Well, make sure not to kill that many, lest you want this spectral nightmare to show up and quickly murder you.
  • Sequential Boss Fight: The Polterghast has 3 phases, one as the Polterghast, one where it transforms into the Necroghast, and a final one when it transforms into the Necroplasm.
  • Shed Armor, Gain Speed: With every phase, more of its stone shell falls off and the faster it gets. Unfortunately, its Defense doesn't go down at all: in fact, it has damage reduction that actually goes up as it loses health.
  • Shielded Core Boss: A curious example. During its last phase as the Necroplasm, it'll gain a bonus 30% damage reduction as long as its clone is alive. This means that the most optimal solution tends to be taking down the clone, and hammering Polterghast before it spawns another one.
  • The Power of Hate: One of the only things that drives the Polterghast is its immutable, collective hatred for Yharim.
  • Tortured Monster: It might be a terrifyingly powerful phantom, but it's still a possibly-unwilling fusion of spirits that Yharim murdered, driven by only hatred and hunger. In some ways, destroying it can seem like a bit of a Mercy Kill.
  • Turns Red: It makes up for its average HP with passive damage resistance that increases as its HP goes down. And of course, as it moves through its phases it gradually gets more and more dangerous. Special mention to its second phase, where its shots literally turn red and become more damaging.
    • Once below 5% HP (10% in Revengeance+), it'll gain a massive speed boost.
    • If you leave the dungeon, Polterghast goes absolutely berserk until you go back in.
  • Vengeful Ghost: Few of Yharim's victims died peacefully, and many cursed the Jungle Tyrant's name with their last breath. Some found peace in their afterlife; others lingered in the physical realm as phantoms, their hatred and anguish immutable even by death. The Polterghast is just the result of a mass fusion of these hate-ridden phantoms.

    The Sentinels of the Devourer 
https://static.tvtropes.org/pmwiki/pub/images/sentinels.png
Cosmic terrors are watching...note 
A group of three wildly different entities that act as the Devourer of Gods's personal squad of second-in-commands. Displaying utmost loyalty to their master, they are bound under a magical pact which has them offer their services for a fragment of the Devourer's own strength. Before the player's arrival, there were originally 5 Servants of The Scourge, and they were searching for Providence in order to expose her to their master. The Rune of Kos, which can only be obtained by defeating Providence, allows the player to use a fragment of Providence's power to lure them out of hiding. They are all supposed to be battled before the Polterghast and after Providence, and each of them drops a material used to craft the Cosmic Worm, which allows you to summon their master.

Each Sentinel must be summoned by the Rune in a different location. Signus must be spawned in the underworld, the Storm Weaver must be spawned in space, and the Ceaseless Void must be spawned in the Dungeon. None of the bosses will enrage, but it's difficult to escape the area the Ceaseless Void and Signus spawn in without them despawning.


  • Arch-Enemy: Providence. Their mission is to track her down and bait her out of hiding so the Devourer can kill her.
  • The Bus Came Back: Once the Devourer of Gods is defeated, all three spawn in order with a third of their health. They must be defeated before take on the mechworm's final form.
  • Degraded Boss: All three of them are summoned by the Devourer of Gods once his first form is defeated (in order: Ceaseless Void, Storm Weaver, and Signus). Fortunately, they only have 1/3 of their HP. Unfortunately, once you take them down, you'll have to deal with the Devourer's second form as well.
  • Dragon-in-Chief: They all look for Providence while Devourer of Gods minds his own business.
  • Eldritch Abomination: A trio of them taking on the forms of a Humanoid Abomination followed by a normal Eldritch Abomination and finally an Animalistic Abomination.
  • Leitmotif: "Servants of the Scourge", which is shared by all three of them. Uniquely, it’s divided into three individual variations for each Sentinel: the first for Storm Weaver, the second for Ceaseless Void, and finally, Signus, Envoy of the Devourer.
  • Magically Binding Contract: Each Sentinel is bound to the Devourer of Gods by a magical contract. In exchange for their unconditional allegiance and service to their master, they are blessed with a fragment of the cosmic serpent's godlike power. The Devourer wields their strength, and they in turn are infused with its might.
  • Mini-Boss: Often regarded as these rather than full bosses, but are far tougher than the average Mini-Boss.
  • Purple Is Powerful: All three have purple as a predominant color much like their master, and they're each very deadly.
  • Land, Sea, Sky: Sort of. Signus is in the lava filled underworld, Ceaseless Void is in the dungeon complex beneath the surface, and the Storm Weaver is miles above the clouds, found in space.
  • Undying Loyalty: They answer only to the Devourer of Gods.

Signus, Envoy of the Devourer

https://static.tvtropes.org/pmwiki/pub/images/signus_1.png

An enigmatic being of unparalleled lethality, Signus is a deadly assassin capable of swiftly killing anyone he's contracted to target. When he made an attempt on Yharim's life, he suffered his first defeat at the hands of the Devourer whom Yharim summoned to aid him. Trapped in the eldritch worm's dimension, he and the Devourer reached a stalemate and Signus eventually gained a grudging respect for him, becoming his deadliest and most trusted Sentinel. Must be spawned in the Underworld.

Drops several weapons themed after him and Twisting Nether, which is used in several weapon recipes but mainly used to complete the Cosmic Worm.


  • The Ace: Highly efficient in his assassin occupation, capable of killing heroes like Statis, as well as the Devourer of Gods' most trusted Sentinel.
  • Action Bomb: Can summon Cosmic Mines that fly at players and explode.
  • All-Encompassing Mantle: Wears a purple cloak that obscures everything on him, minus his glowing eyes, a set of spikes on his back and his rather misshapen lower half.
  • Art Evolution: His cloak became a bit more detailed as he gained two more eyes, all in pink, and his tail became more smog-like.
  • Badass Long Robe: An all encompassing one in purple.
  • Belly Mouth: During one of his phases, his face becomes a mass of black tendrils while he grows a toothy purple maw on his torso.
  • Bizarre Alien Biology: His eyes are glowing purple teeth.
  • Bullfight Boss: During one of its phases, Signus will rapidly lunge at the player several times in succession.
  • By the Lights of Their Eyes: The only thing on his face that’s usually always visible. Except they’re teeth.
  • Cthulhumanoid: His second phase resembles one, where his face is entirely replaced with tentacles.
  • The Dragon: Of all the Sentinels, he is this to the Devourer of Gods, partially due to his power and partially due to the fact that he's the only Sentinel with actual intellect (since Storm Weaver is more animalistic and Ceaseless Void is outright mindless).
  • Death from Above: One of his attacks has him fly above the player and rapidly fire cosmic flames down at them. At half health, he will begin raining cosmic fire from the sky regardless of phase.
  • Evil Sorcerer: One theory suggests he is a mage of insane levels of power.
  • Expy: A hooded being of high levels of magical power as well as some Facial Horror, serving as The Dragon to an Eldritch Abomination related to invertebrates can bring The Hooded One to mind.
  • Flunky Boss: Summons Cosmic Lanterns to provide melee combat assistance and block off the player's escape path while he's charging. Notably, the lanterns have practically no HP but hit almost as hard as Signus himself.
  • Glowing Eyes of Doom: Six pink and narrowed ones.
  • Hero Killer: The actual one who murdered Statis. For added irony, Signus was the one that Statis' clan derived their arts from.
  • Humanoid Abomination: The only humanoid one of the Sentinels. However, it's painfully obvious that he is anything but human.
  • In the Hood: Has a hood that completely hides his face, save for his eyes.
  • Lightning Bruiser: Travels very fast, teleports a lot, and hits like a truck. Taken Up to Eleven in his charging phase, where he can dash across the screen in less than a second.
  • My Greatest Failure: He has only ever failed an assassination once, and that was against Yharim. Said failure eventually resulted in his mutual defeat at the hands of the Devourer.
  • Our Ghosts Are Different: A theory is that he is a wraith of sorts.
  • Playing with Fire: Can summon cosmic flames to blind and burn anyone he fights, which he uses to great effect during his fight by launching rapid barrages of fire. The creation of these ethereal flares is also the only thing all of Signus' attacks have in common, due to his shapeshifting nature making all other clues inconsistent.
  • Predecessor Villain: In a sense. He made his mark on Statis’s clan before allying with the Devourer of Gods, with the clan deriving their arts from him.
  • Professional Killer: Can be contracted to kill just about anyone, regardless of the conditions or his target's defenses. He has only ever failed one mission.
  • Purple Eyes: Six of them. Well, pink, but it’s close enough.
  • Red Eyes, Take Warning: His old sprite had four of them.
  • Shapeshifting: Capable of doing this by virtue of the fact that he lacks a true form. It has even been seen consuming bodies and taking their appearances after. In battle, he can takes on three wildly different forms as he switches phases.
  • Spikes of Villainy: Has 3 spikes on his back. And they move.
  • The Spook: No one knows who the hell Signus really is, be it a wraith, a mage or an interdimensional being, nor what his backstory is like.
  • Teleport Spam: As part of his stealth motif, he will teleport constantly during one of his phases.
  • Turns Red: While his phases are time-based and follow a set pattern, they will become enhanced as he loses HP. As he nears death, he will teleport and move faster, shoot flames faster, and leave behind exploding dust as he charges.
    • Also, at half health he will begin summoning cosmic flames from above in all of his phases.
  • Villain Respect: It eventually became a servant of the Devourer after developing a grudging respect for the worm, which was the only one who ever defeated him.

Ceaseless Void

https://static.tvtropes.org/pmwiki/pub/images/ceaseless_void_9.png
An Eldritch Abomination of horrific power accidentally created when the Devourer was still practicing dimensional tunneling, the Ceaseless Void is a sentient tear in reality barely stabilized by a cosmic steel shell and powerful magic. While research was done on it, it was eventually deemed too powerful to control and left to waste away in the Dungeon, but not before the Devourer took ownership of it via magical contract. Must be spawned in the Dungeon.

Drops some equipment based off of it and also drops Dark Plasma, which is used for several weapons as well as the Cosmic Worm. It also has a rare chance to drop The Evolution, the rare variant of the Arcanum of the Void.


  • Achilles' Heel: The Dark Energy swarms are sensitive to knockback, allowing the player to survive even in the tightest of choke points in the Dungeon as long as their weapons have the knockback to keep the Dark Energy at bay. Another weakness of the Ceaseless Void is weapons with fast usetime or the ability to ignore Mercy Invincibility, as they render the Void's colossal damage reduction mostly useless.
  • Apocalypse How: The second possibility if its casing is shattered: The void fills up and takes out the entire universe, making this a X-4 level. Otherwise, it will collapse in on itself and die.
  • Art Evolution: Has been redesigned to look more jagged, like a maw filled with teeth held together by crystals.
  • Beam Spam: Its only attack besides contact damage is to fire a large homing orb that fires tracking lasers at the player while they're swatting away the Dark Energy swarms. Both the orb and the lasers hurt a lot.
  • Cat-and-Mouse Boss: Ceaseless Void will rain hell on you while it's invulnerable, but doesn't have much to protect itself with when it's rendered vulnerable.
  • Cessation of Existence: If its shell is broken, it could possibly end all of existence, trapping everything in a void between realities.
  • Eldritch Abomination: A semi-sentient living tear in reality that resulted from a flawed teleportation attempt by the Devourer, held in place by a Cosmilite structure which resembles a generic arcanum. It consumes matter and life indiscriminately and turns anything it consumes into shapeless masses of Dark Energy which drain the life force of anything they touch.
  • Flunky Boss: Relies on the melee combat of its Dark Energy minions to attack, but will not hesitate to try and hammer you with its own laser attacks.
  • Glass Cannon: While its laser attacks hit quite hard and its Dark Energy swarms can rack up a ton of damage, even with 99.99% damage reduction 150 HP is still quite pathetic at the time when the player should face itnote . It circumvents this by turning invincible whenever a new horde of Dark Energy is summoned.
  • Homing Projectile: Both its laser orb and the lasers said orb fires will track players.
  • Invincible Minor Minion: After it loses 50% of its health in Revengeance Mode or higher, it will start to summon rings of invincible Dark Energies, which spiral out from their origin point and fly some distance before self-terminating.
  • Omnicidal Maniac: Despite lacking a proper mind, the Ceaseless Void is solely driven on by an all-encompassing desire to consume life.
  • Person of Mass Destruction: Anything that would go near its regurgitated globs of shadow would die instantly. If its armor were ever to be compromised, it could possibly expand and engulf all of existence.
  • Psycho for Hire: The Ceaseless Void is only a Sentinel of the Devourer by the loosest definition: although it is bound to his will, it has no mind of its own and its only drive is to consume the life force of all living things.
  • Shielded Core Boss: Only turns vulnerable if all its Dark Energy is destroyed. It will replenish them at certain HP thresholds.
  • Super Toughness: A Damage Reduction stat of 99.99% means that almost all attacks will do next to no damage to the Void. However, its low HP makes it more than feasible to just chip it to death.
  • The Worf Effect: It took the combined powers of Calamitas and the Devourer of Gods to seal it away.
  • Void Between the Worlds: It is a living version of this. It was created on accident by virtue of the fact the Devourer of Gods didn’t instantly master its dimension jumping.
  • You Will Not Evade Me: Its homing laser portals can teleport if the player strays too far from them.

Storm Weaver

https://static.tvtropes.org/pmwiki/pub/images/storm_weaver_8.png
Click here to see its unarmored state 
The last of the Devourer's species after the worm himself caused humanity to drive it to near-extinction. The Devourer found it as a newborn and, taking pity on it, nursed it back to health and brought it to Yharim, who equipped it with cosmic steel plating just like the Devourer himself. It now remains in space, devouring Wyverns for sustenance, and while it is still rather mentally underdeveloped due to a lack of intelligent creatures to absorb, it is still a force to be reckoned with. Must be spawned in space.

Drops two ranged weapons based off of it, and also drops Armored Shells which are used for a few weapons and the Cosmic Worm.


  • Animalistic Abomination: The most animal-like in the form of a worm, and also more or less Devourer of Gods Jr.
  • Always a Bigger Fish: The creature feasts upon Wyverns that are in the air with it.
  • Anti-Air: Only physically attacks if the player is in the air. In Death Mode, its second form will chase you anywhere.
  • Attack Its Weak Point: Its tail in the first phase. Attacking anywhere else will result in Scratch Damage.
  • Art Evolution: The armored phase looks much more vicious, coated with spines and crystals, while the unarmored phase looks bigger and more threatening than its old sprite.
  • Contractual Boss Immunity: Piercing weapons are the age-old counter to any worm, and many late-game weapons can even do damage for every single tick they touch an enemy. The Storm Weaver's first form, on the other hand, not only takes Scratch Damage from any attacks that don't hit its tail, it also despawns all projectiles after they damage it regardless of which segment it touched. This renders a great number of otherwise powerful weapons next to useless against it.
    • In addition, his second form massively resists piercing projectiles like most of Calamity's worm bosses.
  • Empowered Badass Normal: At first just a newborn of the species Devourer of Gods hails from, it was given the same kind of armored plating and weaponry as the Devourer, making it a formidable opponent despite its mental immaturity.
  • Flunky Boss: Releases Stasis Probes to gun the player down once you attack its body.
  • High-Altitude Battle: It's in space.
  • Laser Guided Tyke Bomb: More or less this for the humans who hunted his species to extinction.
  • Last of His Kind: One of two with the Devourer of Gods.
  • No-Sell: Its head and tail in phase 1 reduce all damage to 0 and 1 respectively, instead of using standard damage reduction - which means that the damage will still be negligible even if you use something from another mod that can deal several million damage. To make matters worse, piercing weapons have no effect on its armor, as it despawns all projectiles once they touch it.
  • Lightning Bruiser: While it appears to be only moderately fast, going airborne to aggro it will make it accelerate at incredible speed. Fitting the "bruiser" part, it hits like a freight train and can take quite a bit of damage in both forms (for different reasons).
  • Pint-Sized Powerhouse: In Death Mode, its second form shrinks down to a fraction of its original length. Despite what that might imply, it has more health, hits far harder, and not only is it harder to hit now, its smaller body also causes piercing weapons to not inflict as much damage as they would have before.
  • Segmented Serpent: However, its piercing immunity makes normal tactics for worm enemies useless.
  • Shed Armor, Gain Speed: After you beat its first phase, its armor shatters and it becomes much faster and more deadly, albeit losing all its defense. Strangely enough, it has more HP in its unarmored state.
  • Shock and Awe: Can spawn orbs which fire lightning bolts.
  • Super Toughness: In its armored state, anything that doesn't hit its tail will deal next to no damage. Unlike Ceaseless Void, however, it's nearly impossible to chip it to death.
  • Turns Red: "Defeating" it once causes it to lose its shell, respawn, and become far more aggressive.
  • Unskilled, but Strong: A lack of intelligent prey to assimilate means that the Storm Weaver still has the mentality of a feral animal. However, considering that it's the same species as the Devourer of Gods and that it's equipped with a similar set of Cosmilite armor, its low intellect isn't really holding it back a lot.

    The Devourer of Gods 

https://static.tvtropes.org/pmwiki/pub/images/the_devourer_of_gods_9.png
Click here to see his final form 

Once an ordinary giant worm with the ability to absorb the powers of those it consumes, countless years of assimilating prey turned the Devourer of Gods into a massive, reality-warping menace who lives in an alternate plane, only leaving to eat and assimilate beings of sufficient power. It drew the attention of Yharim after devouring a platoon of his finest. Instead of killing it, Yharim struck a deal with it, which was a supply of powerful entities to consume in exchange for his eternal servitude. The Devourer accepted and, after being equipped with incredibly durable cosmic steel armor, now serves as one of his most powerful mercenaries. Meant to be fought after dispatching his Sentinels.

The Devourer drops a number of weapons based off of him, but his most important drops are Cosmilite Bars, which are used in most endgame recipes such as the God Slayer Armor. He also has a rare chance to drop the Norfleet and the Skullmasher, the rare variants of the Starmada and Anti-materiel Rifle respectively. Killing him also buffs up the Frost/Pumpkin Moons while making them drop Endothermic Energy and Nightmare Fuel respectively, which are each used in many endgame recipes.


  • Achilles' Heel: Not itself, but the Cosmic Guardian it summons in Revengeance Mode are one of the few worms in the game with no piercing resistance whatsoever. This allows piercing weapons to decimate them in a matter of seconds despite their high HP, in a similar manner to vanilla Destroyer.
    • It is implied by Amidias that his cockiness and bravado is a result of him being very immature and that he still hasn't reached his fullest potential, implying that this is the reason why the player is able to defeat him.
  • A God Am I: Firmly believes himself to be one. Given his immense strength and the fact that he eats gods and assimilates their power, his claims are likely justified.
  • All Your Powers Combined: Takes something away from each of his Sentinels. The most obvious parallel is Storm Weaver, as they're both flying metallic worms who must be attacked at certain weak points to do significant damage. However, the Devourer of Gods also uses Ceaseless Void's tracking laser portals in Phase 2, and changes its behaviour and method of attack on a fixed timer like Signus. In lore, it's also said to gain the abilities of anyone it consumes.
  • Anti-Air: During its airborne "blue" phase, it will only physically attack players that are in the air.
  • Anti-Frustration Features: A few.
    • Minions and homing attacks ignore the Devourer's massively resistant body segments, going for his vulnerable head and tail instead.
    • The Cosmic Guardians are intangible for the first few seconds of their lives. While this makes it impossible to instantly kill them on spawn, it prevents them from dealing cheap hits.
    • While invisible in his second phase, he cannot deal contact damage to the player, although he can still be hit.
  • Art Evolution: It gradually got more and more detailed through its many balances, culminating in the eldritch monstrosity that is his final form.
  • The Assimilator: It absorbs the powers of anything it consumes.
  • Attack Its Weak Point: Its head and tail. Not only do they take 25% more damage from attacks, they're the only parts of its body that don't have massive amounts of damage reduction.
  • Beam Spam: Follows the proud tradition of worm bosses spraying lasers all over the place. However, its second form discards these for laser walls, homing portals that shoot more homing lasers, and streams of fire.
  • The Berserker: Equipping his lore item effectively turns you into this, granting a whopping 50% boost to true melee damage.
  • Boss Banter: The creature's surprisingly talkative during its fight.
  • Boss Rush: After killing the Devourer itself (along with its 3 Cosmic Guardians in Revengeance+), you'll have to take down weakened versions of Ceaseless Void, Storm Weaver and Signus right after each other. And once all three of them are downed, you'll have to contend with the Devourer's final form.
  • Bragging Rights Reward: The Cosmic Plushie, which is obtained by opening The Devourer of Gods' Treasure Bag with a Hardcore character while Deathmode is active. It's a pet-summoning item that summons a miniature anthropomorphic Devourer of Gods known as the Chibii Devourer. As expected, it acts like a normal pet item... except not. If you and Chibii are in very dark areas, Chibii Devourer may meow, scream, or stab the player for 500 damage.
  • Bullfight Boss: Well, half the time. It spends fifteen seconds flying and another fifteen seconds chasing players on the ground... though this is never an excuse to underestimate its insane killing power.
  • Cannibalism Superpower: As said before, he gains the powers of anything he eats.
  • Contractual Boss Immunity: The Devourer's body segments are massively resistant to damage, making piercing weapons next to pointless save to hit its weak points easier. If that wasn't enough, its body segments also reduce the damage of weapons depending on their piercing power.
  • The Dragon: With Calamitas gone, he serves as Yharim's right-hand man and go-to monster when he wants something killed. Even after Calamitas comes back, he still holds a position as the Jungle Tyrant's most deadly mercenary.
  • The Dreaded: The mere fact that it existed drove humanity to promptly hunt its species to extinction before they could get as powerful.
  • Deadpan Snarker: It sounds positively exasperated if you get hit by its tail, criticising your dodging skills.
    "Are you honestly that bad at dodging?"
    "Of all my segments to get hit by..."
  • Eaten Alive: Ninety percent of all player deaths against this boss will be to its freakishly powerful jaws. Notably, this was also apparently Yharim's preferred method of executing traitors.
  • Eldritch Abomination: A giant predatory worm of immense power that possesses reality warping capabilities and resides in its own dimensional plane. Simply being near it warps gravity and it can seemingly phase out of reality at will.
  • Empathic Environment: The sky will alternate between pink or blue in his presence to signify his phase changes. When he's at low health (or always in Deathmode), the sky will turn pitch-black instead.
  • Evil Is Hammy: Boy, is he ever. Just take a look at his quotes.
  • Flunky Boss: It can summon smaller versions of itself at certain health intervals in Revengeance mode. In addition, he will call his Sentinels to assist him when first killed.
  • From Nobody to Nightmare: It started life as a ravenous but otherwise normal worm, albeit capable of assimilating the power of those it killed. Eventually it grew so strong that it developed the ability to tear holes into alternate dimensions and set up home there, where it turned into the cosmic monstrosity it is now. Believe it or not, it got even worse when it agreed to serve Yharim and the Jungle Tyrant decided to give him superpowered, nigh-impenetrable cosmic steel armor. And apparently he still isn't at the extent of his power yet. Yharim explicitly states that he would have needed to personally eliminate the Devourer if he had kept getting stronger.
  • Gravity Screw: Simply being near it inflicts either Extreme Gravity or Warped depending on its current attack phase, which cripple flight time and distort falling speed respectively.
  • Hero Killer: Yharim generally sics him on any heroes that oppose him, Braelor being one of the notable examples. On a meta level, the Devourer is notoriously competent at ripping unfamiliar players to shreds time and time again.
  • Hold the Line: When at about half HP in its second form it will start occasionally turning invisible for a bit while firing laser walls to harass you from all sides. Fortunately, it can't do contact damage while firing the laser walls.
  • Kill the God: It's in the name. It loves devouring gods and absorbing their powers. Astrum Deus was one of his more notable victims.
  • Last of His Kind: He was until he discovered the Storm Weaver. Although it was technically his fault, as he gained such a terrifying reputation that humanity hunted his species to extinction.
  • Leitmotif: "Scourge of the Universe".
  • Lightning Bruiser: Moves scarily fast, dishes out One-Hit Kill attacks like nothing, has a ton of health and resistance - and that's just its first form...
  • Names to Run Away from Really Fast: The Devourer of Gods.
    • Even the name of its theme, Scourge of the Universe, qualifies in its own right.
  • No Fair Cheating: Trying to butcher it won't do anything but earn an angry response. Trying to outrun it with accessories like the Omega Core or Soul of Dimensions cause it to speed up with you - potentially reaching speeds so high that he catapults himself off the world map entirely. Because of this, the Omega Core was coded to not work during the fight in a joint effort from Thorium and Calamity's dev teams.
  • No-Sell: The Devourer of Gods (and his Cosmic Guardians in Revengeance+) will nullify any attack that deals more than 1/2 of their max HP in one hit - making attempts to instakill it with something like Cheat Sheet's butcher function do absolutely nothing. In fact, the Devourer will actually mock you if you try to do so.
    You think...you can butcher...ME?
  • Omnicidal Maniac: It used to tunnel through the world, slaughtering anything and everything it could find.
  • One-Hit Kill: In Deathmode, getting hit by its head segment is an instant kill regardless of your HP. Because of the way the attack works, it's notable for being able to kill you even if you have some kind of godmode active.
  • One-Winged Angel: After you seemingly kill him, he returns in a larger and more monstrous final form.
  • Pet the Dog: The Devourer's sparing of the Storm Weaver can seem like this. Subverted with the fact that it would not hesitate to destroy the Storm Weaver should it ever turn against him.
  • Physical God: Mildly ironic that the entity that prides itself on devouring gods is essentially a god as well.
  • Playing with Fire: In its second phase, it has the ability to occasionally breathe a stream of purple flames which deal a ton of damage and hammer you with a lengthy dose of God Slayer Inferno. In addition, touching him will inflict the God Slayer Inferno as well.
  • Psycho for Hire: It doesn't serve Yharim out of respect so much as the opportunity to chew on some more gods. Although it has been stated that the Tyrant King is the only one powerful enough for him to fear.
  • Purple Is Powerful: Primarily associated with the color purple, and one of the most powerful entities in canon.
  • Rare Random Drop: Has a 1% chance to drop the legendary flail Cosmic Discharge on Revengeance+, which can be boosted to 5% if you fight her with the Defiled Rune active. The Cosmic Discharge functions similarly to the Solar Eruption, but it deals far more damage and grants the user the Cosmic Freeze buffnote  upon striking a foe.
  • Reality Warper: It wasn't this until it consumed enough prey. Now, however, its very presence causes gravity to go haywire and it can rip holes through dimensions at will.
  • Resurrective Immortality: It's been stated by Word of God that it's impossible to truly kill him, only to temporarily defeat him. No matter how many times you defeat him, he'll just come back again later.
  • Segmented Serpent: The thing is even larger than Destroyer, easily spanning most of an unzoomed minimap, and immensely more dangerous. You can't even take advantage of its size like most worms, due to its body taking little to no damage from all attacks.
  • Sequential Boss: Once you kill the damn thing, then you'll have to take care of his Sentinels again. Kill them, and he'll return again, extra powerful and quite angry.
    It's not over yet, kid!
  • Stronger with Age: Countless years of hunting, killing, and consuming its foes along with their power has turned this creature from a mere worm into the cosmic serpentine wrecking ball you have to fight.
  • Super-Persistent Predator: Once summoned, the Devourer of Gods will not stop until you kill it or it kills you. Even if you teleport away from one corner of the world to the other, it will hunt you down.
  • Super Speed: Can effortlessly overtake the player, even with Seraph Tracers equipped... which isn't much, but it also scales with their acceleration. While this isn't too significant in normal gameplay, using other mods to massively increase your speed will also increase the Devourer's speed as he chases you. Even if you're hurtling along at over four thousand miles per hour, the Devourer of Gods is still faster.
  • Theme Music Powerup: When you kill him and all of his Sentinels, Universal Collapse kicks in as the Devourer unleashes its final form in one last attempt to destroy you. For bonus points, the quiet intro to the song plays during the downtime between the Sentinels and his final form, with the song kicking in at full force when he appears.
  • Took a Level in Badass: The Devourer used to be nothing more than a direct Destroyer clone that could be fought immediately after Plantera. It was then overhauled, buffed, moved to post-Providence, and continued receiving countless mixed balance adjustments over a long period of time. Now indistinguishable from what it used to be in the past, the Devourer has become one of the deadliest and most renowned bosses the mod has to offer.
  • Trash Talk: Yes, really. The interdimensional god-killing cosmic worm is not only the chattiest boss, but also very prone to throwing out taunts and snide remarks whenever the opportunity presents itself.
  • Turns Red: When you deplete its enormous health bar and destroy his Sentinels, all becomes calm for a few seconds...then he comes back with a new sprite and a deadly new arsenal of attacks.
    A GOD DOES NOT FEAR DEATH!
  • Unskilled, but Strong: According to Amidias, the Devourer is extraordinarily strong (especially with its theoretically infinite potential for growth), but this is upset by his young age, foolhardiness, and extreme laziness.
  • Villainous Breakdown: It's not as evident, but the Devourer seems to mostly speak with a snarky or mocking tone for the entirety of the fight...except when it's at critical health.
  • Villain Respect: After reaching a stalemate with Signus, it eventually developed a grudging respect for the ethereal assassin.
  • Wolfpack Boss: It can summon a Cosmic Guardian in Revengeance Mode when at 60% life, which is a Wyvern-like worm that flies at players and attempts to do ludicrous contact damage to them. When at 20% life, it will summon 2 more. If you do too much damage to the Devourer at once, you may have to contend with all three Cosmic Guardians at once.
  • You Will Not Evade Me: His homing laser portals in his second form will teleport to players if they stray too far away from them.

    Jungle Dragon, Yharon 
This is my message to my master,
This is a fight you cannot win.
I think that past your great disasters,
Their victory stirs beneath your skin...
https://static.tvtropes.org/pmwiki/pub/images/jungle_dragon_yharon.png
My dragon deems you an unworthy opponent...

The Jungle Tyrant's personal pet, who must be fought in the Jungle. Given to Yharim as an egg by his mother, the egg prematurely hatched when it was tossed into lava along with its owner's family. Yharon then saved Yharim from a fiery demise before assisting Yharim in his rise to power by crushing all the previous Jungle tyrants. Now, he serves as Yharim's most powerful servant, as well as his closest friend.

Uniquely, Yharon will deem you unworthy and flee battle upon reaching critical health the first time you fight himnote , buffing up the Solar Eclipse while allowing the buffed Mothrons to drop Darksun Fragments, an endgame crafting material. Taking down a buffed Mothron will unlock Yharon's final phase and subsequently allow him to be killed.

Drops a number of extremely powerful fire-based weapons, and also has a rare chance to drop the Void Vortex, the rare variant of the Voltaic Climax. After defeating after being deemed "worthy", he will also drop Yharon Soul Fragments which are used in many endgame recipes. Killing him for real also allows Auric Ore to generate in your world, unlocking the highest tier of standard weaponry available.


  • Blow You Away: Takes this Up to Eleven by creating flaming tornadoes. He can create smaller Flarenados which split apart eventually, along with gigantic Infernadoes. He also creates special rainbow Infernadoes along the border of his arena which One-Hit Kill players.
  • Bullfight Boss: He charges a lot, three times in a row during his very first phase alone.
  • Contractual Boss Immunity: Yharon uniquely resists the damage reduction penalty that Ichor and Cursed Flames give - instead of decreasing his DR by 25%/20% respectively, both of the effects will decrease his DR by a much weaker 5%. He shares this with Providence.
  • Death from Above: In his final phase, he has the ability to rain down massive quantities of flaming meteors from the sky.
  • Death Song: The lyrics to "Roar of the Jungle Dragon" lead up to his death, with the Jungle Dragon using his last words to warn his master of the great danger that the Player poses to him.
    If you proceed, I will not blame you.
    I will move forth and win your war.
    But if I should die before you continue,
    You shall have heard my final dying roar.
  • Defiant to the End: "Roar of the Jungle Dragon" makes him out to be this, fully aware that he is to die but will continue fighting for Yharim out of Undying Loyalty.
  • The Dragon: Yharim's personal pet, closest companion, and deadliest minion. Bonus points for actually being a dragon.
  • Empathic Environment: Tints the screen orange, possibly from the enormous amounts of fire he's tossing around.
  • Extra Eyes: If you look close enough, you'll notice that he actually has four eyes.
  • Feathered Fiend: Has many traits associated with birds, and most certainly not your friend.
  • Flunky Boss: Spams Detonating Flames, which chase players while shooting fireballs.
  • Hoist by His Own Petard: He gave this to the original Jungle tyrants - if they hadn't thrown Yharon's egg into the lava just to spite his family, Yharon wouldn't have hatched and went on to annihilate them later.
  • Hold the Line: When he hits critical health (after killing a buffed Mothron), he will go invulnerable for about a minute, regenerates a chunk of his health bar (the entire bar in Death Mode), start spamming Detonating Flames and Infernadoes, and begin raining fireballs from the sky while dashing all over the place.
  • Homing Projectile: Can spam homing fireballs. In his last phase, some of the meteors that he rains from the sky will track players.
  • Invincible Minor Minion: In Revengeance, he summons an Angery Flame in his last phase which is invincible and chases players while shooting homing fireballs.
  • Leitmotif: "Infernal Catharsis".
  • Last Stand: Yharon's second phase. Just when you think he's dead, he regenerates most of his health back and launches one final assault - one that gets increasingly frantic and desperate as he nears death. Yet from Roar of the Jungle Dragon playing in the background, it's clear that these are Yharon's final moments, and he knows it.
  • Lightning Bruiser: Moves incredibly fast, has enormous HP, and deals near-lethal damage with each hit. He even spices up his attacks with countless fireballs and tornadoes.
  • Living Emotional Crutch: Yharon was the only thing comforting the Jungle Tyrant during times of depression
  • Morality Pet: Yharon is living proof that Yharim still has the capacity to love another living thing.
  • No Final Boss for You: The first time you bring him to low health (assuming you've already slain Providence and the Devourer of Gods, Yharon actually deems you an unworthy opponent and leaves the fight entirely, making you unable to kill him (he will, however, still drop his equipment sans the Yharon Soul Fragments). In order to unlock his last phase (and therefore kill him), you need to kill a newly-buffed Mothron, then challenge him again.
    "My dragon deems you an unworthy opponent. You must acquire the power of the dark sun to witness his true power."
  • No-Sell: Any attack that deals over 1/10 of his max HP in a single hit will be completely nullified, making him quite impossible to One-Hit Kill even with something like a butcher function.
  • One-Hit Kill: Touching the rainbow-colored Infernadoes marking his arena border will instantly kill you. Like Devourer of Gods' head in Death Mode, not even some form of godmode will protect you.
  • Our Dragons Are Different: Despite having a lot of draconic traits, Yharon has quite a few avian attributes, such as his feathers, beak, and wings. He also seems to have a phoenix motif of sorts, since he kind of looks like one and gets "reborn" in his last phase.
  • Physical God: Is heavily implied to have some kind of divine power, judging from his incredible strength and the fact that killing him "blesses the caverns with a godly aura".
  • Playing with Fire: He uses all manner of apocalyptic-level fire attacks, from explosive fireballs to meteor showers to gigantic flaming tornadoes. It's a miracle the place isn't blasted into a crater yet.
  • Power at a Price: Having his lore item in your inventory lets you fly almost indefinitely, but also cuts all of your damage by 25%.
  • Ramming Always Works: Once he's hit critical HP in his second phase, he will discard all of his projectiles and resort to nonstop charges.
  • Rare Random Drop: Has a 1% chance to drop the magic weapon Yharim's Crystal, which cannot be boosted with the Defiled Rune. The Crystal is an immensely powerful Wave Motion Gun akin to a heavily upgraded Last Prism, which guzzles incredible amounts of mana but pumps out absolutely staggering amounts of DPS in return.
  • Sequence Breaking: Defied. Discounting the whole "kill a buffed Mothron to unlock his last phase" thing, he can actually be fought right after Moon Lord, since Bumblebirb can technically be fought as soon as you get Luminite. However, if you somehow manage to bring him down to low health, you won't even be able to access the buffed Eclipse until both Providence and the Devourer of Gods are killed, although you will still get most of his loot.
    "My dragon deems you an unworthy opponent. Snuff out the profaned flame and destroy the god devourer to witness his true power."
  • Signature Roar: A harsh roar that also features a distinct, high-pitched whining sound.
  • Taking You with Me: Upon death, he explodes into a ring of obscenely damaging fireballs that home in on the nearest player.
    • It's not really a Kaizo Trap, though - while the attack deals so much damage it's perfectly liable to kill a low-health or unaware player after his battle, he'll still drop his loot.
  • Teleport Spam: Can do this in his semi-final phase, and will also do this in his last phase.
  • Tornado Move: Flaming ones that can possibly pull off a One-Hit Kill, no less.
  • Turns Red: He very clearly defines that he wants the player to remain in a certain area (read: gigantic One-Hit Kill firenadoes), and should you leave the area he gets even more dangerous until you return.
  • Undying Loyalty: The lyrics to "Roar of the Jungle Dragon" all but state that Yharon knows that he's already lost the fight, but he still persists because of his absolute loyalty to Yharim.
  • Wreathed in Flames: During the transition to his last phase, his entire body becomes engulfed in harsh flames.

Superbosses

    Supreme Calamitas 
The end has come; the witch and the prophecy,
Deciding fates with the world on the line.
Who shall emerge from the ashes of calamity?
How shall this fable end through these legends intertwined?

https://static.tvtropes.org/pmwiki/pub/images/supreme_clam.png
Do you enjoy going through hell?

An extremely powerful mage and a member of the clan of that was exiled from the civilization of the Underworld, Calamitas' heritage granted her the ability to wield fearsome brimstone magic. After watching her family get put to death by a rivalling faction and wreaking bloody vengeance on her family's killers, she wandered to the Jungle, driven by a mysterious voice, where Yharim found her and recruited her into his army. But the good in her still existed, and eventually she betrayed Yharim to help some of his strongest enemies. The Jungle Tyrant then cursed her in a rage, and eventually the curse drove her insane and caused her to return to Yharim's forces, where he relinquished the curse in exchange for her utmost loyalty and unwavering cruelty towards all who would oppose him. The current ultimate boss of the Calamity Mod, designed to be a final test of both a player's skills and their power.

Supreme Calamitas drops Calamitous Essence to make Shadowspec Bars, which in turn allow you to make your own developer-grade Game-Breaker items. On expert, she also drops an additional one of said developer items, and she drops additional loot when fought on even harder difficulties.


  • Always Someone Better: As powerful as she is, she says that she stands no chance against Yharim.
  • Art Evolution: Like her previous form, she went from a psuedo-resprite of Retinazer to a flaming, wood/metal eyeball like entity. A further update made her flames more polished, and added a more obvious tell when she's in phase 2.
  • Bonus Boss: Currently the only Superboss, and will be until Yharim's addition bumps her down to a normal boss.
  • Boss Banter: As powerful as she is, she's even more talkative than the Devourer of Gods.
  • Bragging Rights Reward: Killing her on Death Mode will give you the Levi item, which allows you to summon a mini Leviathan pet. This is a Shout-Out to the Youtuber Leviathan, who does numerous challenges involving the mod, including no-hit fights with all the bosses in Death Mode, including Supreme Calamitas herself.
  • Bullet Hell: At fixed HP thresholds, she will turn invulnerable and spam a gridlike barrage of fireballs along with homing blasts that erupt into more bullets. As she loses HP, the bullet-hell phases become more and more hectic - adding more elements and hazards.
  • Call-Back: Her theme incorporates parts of "The Step Below Hell" and her previous Leitmotif "Raw, Unfiltered Calamity" - the former because of her implied connection to the Brimstone Crags, and the latter because...well, it was her doppelganger's theme. More notably, it includes parts from Now Stop Asking Where, which was her previous placeholder theme.
  • Contractual Boss Immunity: She massively resists the Apotheosis tome and the Son of Yharon minion, reducing their damage to 33% and 50% respectively.
  • Damage-Sponge Boss: She has 5,000,000 HP in Normal alone, which only gets higher with difficulty, capping out at a whopping 10,000,000 HP in Death Mode.
  • Deadpan Snarker: She's just as snarky as the Devourer of Gods. If not, even more so. Whenever she's summoned after the player has been killed by her for enough times, she will start the battle with a mocking quote.
    After 4 deaths: "Don't get me wrong, I like pain too, but you're just ridiculous."
    After 5 deaths: "You must enjoy dying more than most people, huh?"
    After 20 deaths: "Do you have a fetish for getting killed or something?"
    After 50 deaths: "Okay, I'm done counting. You probably died this much just to see what I'd say"
  • The Dragon: Serves as this to Yharim.
  • Easter Egg: Kill her on your fourth attempt, and you will get an item called Lul. It instantly kills the player if equipped, but if their name is Fabsol and there are no no town NPCs active, it grants complete immunity to damage.
  • Eldritch Abomination: Her very presence hampers your healing, she is ungodly powerful and she can spawn clones of herself which are plenty damn nasty in their own right as well, and if the backstories involving her are of any indication, she is capable of drying up entire oceans and laying waste to entire civilisations.
  • Empathic Environment: Tints the screen blood-red.
  • Face Death with Dignity: As constrasted to her Villainous Breakdown throughout the fight, she reacts to her death with Dull Surprise. Given that she knows she'll come back anyway due to the player re-summoning her to farm more Calamitous Essences and Developer Weapons, this is justified.
  • Faux Affably Evil: Her defeat quotes show a friendly attitude to the player despite how much of a total sadist she is, like congratulating the player and giving them a reward. This may be the result of her Medium Awareness.
  • Flunky Boss: She can summon Supreme versions of her brothers to assist her at 45% HP, and can summon Soul Seekers at 20% HP. Twice throughout the fight, she can also summon a large worm boss called Sepulcher to help her out by spamming brimstone blasts.
  • Invincible Minor Minion: At about 30% HP, she will summon several giant brimstone monsters that slowly chase the player.
  • Leitmotif: "Stained, Brutal Calamity," which is separated into 4 distinct parts that play during different segments of the battle:
    • Grief, a grandiose yet oppressive theme which emphasizes her sheer power. The Ominous Latin Chanting lyrics are about her internal thoughts about the battle, including her questioning if fighting you is the right thing.
    • Lament, which keeps up the upbeat and threatening nature of the song while adding in lyrics from DM DOKURO himself, which question the justifications of the player's rampage.
    • Epiphany, which brings a sense of epic finality as it repeats the main melody of the song (which was previously heard in Raw, Unfiltered Calamity) in tandem with more Ominous Latin Chanting lyrics depicting the climax of her battle against the player.
    • Acceptance, which suddenly drops all of the song's grandiosity and becomes outright somber, representing how Calamitas has accepted her defeat and conceded the fight.
  • Leaning on the Fourth Wall: Some of her quotes show that she has some knowledge about the game mechanics, such as cheating and calling the weapon that she dropped as a "reward". She even comments on how she'll keep returning once killed, since the player will likely resummon her at some point.
  • Level Drain: Uniquely, during her fight, she disables the effects of any permanent Adrenaline power-ups the player might have - resulting in the Adrenaline meter always filling up in 45 seconds, even if it normally would have filled in less.note 
  • Lightning Bruiser: The most extreme version in the game. She can dash across the screen in a fraction of a second, has tons of health, and can kill you swiftly in a few hits.
  • No Fair Cheating: She has a large number of special restrictions in place to prevent you from cheesing her fight.
    • Healing from sources besides Healing Potions is massively reduced.
    • The Titanium Armor's Shadow Dodge effect cannot be triggered while she's alive.
    • She builds her own arena around you to cut off mobility and stop you from using yours.
    • If you take less than 100 damage from one of her attacks on Revengeance+, she will instantly kill you.
    "You aren't hurting as much as I'd like...are you cheating?"
    • Healing from sources besides potions is greatly reduced.
    • If you somehow kill her too quickly despite her immunity to One-Hit Kill attacks, she won't drop anything except Supreme Healing Potions.
  • No Good Deed Goes Unpunished: She betrayed Yharim and granted power to Braelor and Statis, two of Yharim's most valiant opponents... and was promptly inflicted with a horrific curse by Yharim, causing her to slip into insanity.
  • No-Sell: She has the ability to negate any attack that would have dealt more than 10% of her HP in one hit. This makes her virtually impossible to One-Hit Kill, even with overpowered gear from other mods.
  • One-Hit Wonder: Having her lore item in your inventory will cause contact with anything damaging to instantly kill you.
  • Orbiting Particle Shield: Creates one made of Supreme Soul Seekers at 20% HP. Made harder by the fact that the Soul Seekers can fire back as well.
  • Person of Mass Destruction: Wields enough power to handily decimate civilizations and incinerate entire oceans.
  • Playing with Fire: Launches fireballs and flaming missiles that explode and inflict the devastating Abyssal Flames debuff.
  • Recurring Boss: A much, much harder version of Calamitas. However, they fight very differently.
  • Red Baron: A number of the supplementary lore entries refer to her as "The Bloody Inferno".
  • Red Eyes, Take Warning: She IS the red eye.
  • Resurrective Immortality: She seems to have a form of this, judging from the quote that she gives upon defeat and how she will reference her past deaths if killed more than once.
    Upon death:At long last I am free...no...wait. I'll just keep coming back, just like you. Until we meet again, farewell.
    Right before death if the player has defeated her before: Perhaps one of these times I'll change my mind after all these deaths...
  • Shielded Core Boss:
    • Twice during her fight (at the start and at 8% HP), she will generate a number of Brimstone Hearts that make her invincible until destroyed. Made harder by the fact that she also summons the Sepulcher, a large worm boss for you to contend with.
      • Not to mention that the Sepulcher itself is one as well - it can't be harmed normally, but will die instantly when all of the Brimstone Hearts are destroyed.
    • If you're playing on Revengeance or higher, she is invincible until all her minions are killed.
  • Shout-Out: Her dialogue used to be more or less a blatant Expy of Sans.
    "You got hit too many times...noice. Did you take lessons from Leviathan?"
  • Smug Snake: She’s powerful, there’s no denying that, but she’s very cocky and smug when she enters the fight, and as she starts to lose her cocky demeanour disintegrates into impotent rage and ultimately despair when she realises that she’s too weak to win and can't convince you that Yharim is indeed invincible.
  • Sore Loser: Zigzagged. If you beat her on your first attempt, she accuses the player for cheating, even if they really didn't. However, she is far less sore outside of this - she will downright congratulate you if you beat her within a reasonable number of attempts, and she still drops a Developer Weapon after accusing the player for cheating, all while being calm about it.
  • Straw Nihilist: She wholeheartedly believes that there is nobody who can stop Yharim, and constantly implores the player to just give up on trying to beat him.
  • Tranquil Fury: If you somehow use someting like another mod's butcher function or an overpowered weapon from another mod to One-Hit Kill her, not only will she only drop healing potions, she'll reply with a single chilling line.
  • Tron Lines: Pulsating red ones only visible during her second form.
  • True Final Boss: The current hardest boss in the Calamity Mod.
  • Turns Red: Exiting her arena with something like the Rod of Discord will cause her to enrage, massively boosting her projectile speed and making her take Scratch Damage from all attacks.
    • She also has a visual example, where her body starts pulsing with red light when she drops below 40% HP.
  • Used to Be a Sweet Kid: She actually used to be a nice enough person as a kid. Then her family got killed, pushing her over the edge. Then she met Yharim, and things got even worse.
  • Villainous Breakdown: As you slowly overpower her in her fight, she’ll retort with begrudging approval, then disbelief and rage before sinking into despair as she realizes she's about to be defeated.
  • Villain Respect: After beating her down enough, she'll react with reluctant approval before the aforementioned Villainous Breakdown. In addition, she will straight-up praise you for beating her within a reasonable number of deaths.
    "One death? That's it? ...I guess you earned this then."
    "Two deaths. Good job. Here's your reward."
    "Third time's the charm, huh? I guess it is. Here's a special reward.
    • If the lyrics to Stained, Brutal Calamity are any indication, she acknowledges the power of the player and is secretly wondering whether she should even bother fighting with someone who could possibly save mankind.

Planned Bosses

    Draedon 

https://static.tvtropes.org/pmwiki/pub/images/draedon.png
Concept art of Draedon by Oxymercuration.
A cyborg who serves as Yharim's weapons/armor expert and advisor. Little is known about him, and most of his lore is spread solely through Word of God and Word of Dante. He is planned to be added in a future update, meant to be fought after Yharon but before Supreme Calamitas.

He is a genius responsible for creating a number of items, most notably the Exoblade (which was his personal sword). He is also responsible for creating Astrum Aureus, and the Draedon's Forge is named after him. In this version of Terraria's story, he also built the Mechanical Bosses.


  • A.I. Is a Crapshoot: Was on the receiving end of this when the Mechanical Bosses (that he built) suddenly went rogue and ran amok, something he failed to fix before they ran off to do whatever they pleased.
    • A less traditional version is when Astrum Aureus became infected by the Astral virus.
  • Always Someone Better: The player is this to him. Not only do they somehow pick up on his master craftsmanship, they recreate his signature weapon and even his augmented heart. As if that's not enough, the player then proceeds to make six more weapons in the style of his Exoblade, all of which are of comparable or even greater power, and two weapons that actually use said weapons as their crafting materials.
  • Badass Transplant: He apparently has a mechanical heart, the aptly named Draedon's Heart, which can utilize nanomachines, not unlike a certain senator. When the player uses it, it passively allows them to build up Rage while allowing them to gain massive buffs when standing still.
  • Cool Sword: You know the Exoblade? As in the insanely powerful Infinity +1 Sword which has to be built up over the course of the whole game and can pretty much deliver a Curb-Stomp Battle to nearly anything? Well, that was originally Draedon's personal weapon.
  • Evil Laugh: Has one laced with Creepy Monotone before The Stinger at the end of Blood Coagulant.
  • Extra Eyes: Played with. He seems to lack conventional eyes, but each "eye" seems to be made up of numerous other ones arranged into a hexagonal formation.
  • Flunky Boss: Foreshadowed to be one by Amidias.
    Amidias: Draedon's style of confrontation is very... alien and hands off. You may be more likely to fight any one of his mechs before taking him down.
  • Lean and Mean: He's very tall and incredibly skinny.
  • Machine Monotone: Seems to display this, if his cameo at the end of Blood Coagulant is anything to go off of.
  • Mad Scientist: It's been heavily implied that he's not exactly okay in the head, and he also seems to have a knack for designing incredibly destructive weaponry. Aside from crafting weapons for Yharim, he also built the Mechanical Bosses and Astrum Aureus. According to Yharim, the Destroyer could have proven useful as a resource collector if Draedon didn't have an obsession with turning everything into a tool of destruction.
    Cyborg: Draedon? He's...a little 'high octane' if you know what I mean.
  • Punch-Clock Villain: Sees doing work for Yharim as some sort of side job and is unusually complacent in doing what he does, suggesting that he lacks malevolent intention. Additionally, the Mechanical Bosses were not inherently malevolent until their AIs went rogue and ran away.
  • SkeleBot 9000: His body vaguely resembles a robotic skeleton - although it's mostly because of how thin he is.
  • Ultimate Blacksmith: Is more than capable of forging the most powerful weapons in Calamity Mod, with the most notable one being the legendary Exoblade, and is heavily implied to be responsible for the creation of Yharim's Powered Armor as well. Aside from this, he's responsible for the Draedon's Forge, which is even more powerful than the cultists' Ancient Manipulator from the vanilla game and is required to make nearly every endgame weapon in the game.
    Yharim 
https://static.tvtropes.org/pmwiki/pub/images/yharim2.jpg
Concept art of Yharim by Poly.
The resident Big Bad and Jungle Tyrant. Not too much is known about him besides the fact that his family was thrown into the Underworld for an unknown offense, and Yharon saved him before the pair crushed the corrupt leaders of the Jungle and took over as its master. Yharim's goal seems to be total control of Terraria and his influence is felt throughout almost every aspect of the mod, but he has yet to appear in person. This is to change soon, where he is planned to be the Final Boss of the mod.
  • Affably Evil: If the lore items really are written by him, the language used in those items are pretty formal, and in Plantera's lore item, he even wishes you luck in dealing with the fallout that is the post-Plantera Dungeon and the post-Plantera Abyss.
  • Always Someone Better: To the player once the Auric Tesla armor is acquired. His official appearance shows him clad in what appears to be a mechanically augmented version of the armor, fueled by his Stims. This also gets inverted somewhat - one of his family's superweapons, the Astreal Defeat, is eventually used as a material for the far stronger Heavenly Gale (and that can be further upgraded into the Drataliornus).
    • Made even more apparent with the update that made specialized variants of the Auric Tesla Armor - his armor still resembles the old Master of All armor that combined almost all the perks of the current variants into one set.
  • Arch-Enemy: He has made several over the course of the story. Notable ones are Braelor, Statis, Permafrost, and Providence.
    • With the addition of some more recent lore, the Lunatic Cultist may have been this, after he stopped Yharim's attempt to summon the Moon Lord.
  • Asskicking Equals Authority: The ruler of the jungle, and by far the most powerful fighter in his forces. He's been stated to be powerful enough to deliver Curb-Stomp Battles to the likes of The Devourer of Gods and Supreme Calamitas.
  • Badass Cape: Wears a long blue-and-gold one that borders on All-Encompassing Mantle.
  • The Beastmaster: He seems to have a penchant for controlling beasts. Yharon is the most notable example but he has also shown to be able to control Queen Bees (and by extension the Plaguebringer Goliaths).
  • Bling of War: Much like the Auric Tesla Armor it's based off of, his Powered Armor is golden.
  • Cool Helmet: A golden, mechanical one with a vertical-slitted visor. It's nearly identical to the older Auric Tesla Helmet, which was back when the armor was a full-fledged Master of All set.
  • Cool Sword: As seen in his official artwork, he wields a massive, 3-meter long, intricate broadsword which bears a striking resemblance to the True Tyrant's Ultisword you can make in-game.
  • Deal with the Devil: After hearing that the Devourer of Gods had just butchered a platoon of his best soldiers, he struck a deal with the worm: in exchange for his eternal loyalty, he would feed the Devourer any entities of power he could capture. The Devourer accepted.
  • The Dreaded: Word of God states that the only thing that the Devourer of Gods fears is Yharim himself, because he could defeat the Devourer in a few hits when at full power.
  • Despair Event Horizon: The lyrics of "Roar of the Jungle Dragon" imply that he's hit this, to the point where he may have purposely let the player become a being of godlike power just to watch them lay waste to his legacy and empire.
  • Even Evil Has Loved Ones: Despite all his asshattery towards practically everyone he meets, he seems to genuinely love his pet Yharon. In addition, the murder of his family was stated to be his Start of Darkness.
  • Even Evil Has Standards: When he accidentally created a type of infectious nanomachines that could rot their victim from the inside out, even he promptly declared them too dangerous for use and locked them away. Unfortunately for him, someone snuck them into his newest project, infecting the entire Jungle and creating the Plaguebringers, Plague Chargers, and Plaguebringer Goliaths.
    • The lore items gotten from certain bosses (which are implied to be written by him) show that he has at least a few redeeming qualities, such as pitying the Brimstone Elemental despite his hatred of the underworld.
  • Evil Is Petty: His default response to things he disagrees with is usually Disproportionate Retribution.
    • When the Sea King Amidias refused to help him resurrect the Moon Lord, Yharim had Calamitas evaporate the whole ocean, laying waste to his kingdom and causing the Desert Scourge to go on a rampage.
    • He had Calamitas lay waste to the Underworld capital just because he hated it. Similarly, he wanted to learn ice magic from Permafrost just so he could lay waste to the Underworld.
    • On the subject of Permafrost, when the archmage refused to help him Yharim trapped him and his fortress in a chunk of ice forever, creating Cryogen.
    • Upon hearing that Calamitas betrayed him, he promptly cursed her with a spell so powerful that even though it was imperfectly cast, it still managed to drive her into insanity.
  • Evil Overlord: He rules over the jungle from his temple with an iron fist and commands an entire army of incredibly powerful beings such as cyborgs, reality-warping abominations, and god-level beasts.
  • Freudian Excuse: His family was incinerated in the Underworld and only he survived because Yharon saved him. He consequently decided to overthrow all of the previous Jungle Tyrants and take over in their place.
  • Hoist by His Own Petard: Pretty much everyone Yharim hurt in the lore ends up being useful in one way or another to the player, who's objective is to kill him.
  • I Control My Minions Through...: A mixture of Loyalty and Fear. While Yharim's closest allies are mostly drawn to him by his overwhelming charisma, he's definitely not above using the occasional threat of force to keep them in line.
  • I Have Many Names: He has a lot of titles that pop up throughout the game, although the most common ones are Jungle Tyrant, Yharim or Yharim, Lord of the Cosmos.
  • Jerkass Has a Point: The lore entry for the Underworld states that it was morally corrupt beyond repair. Come the lore release for the Brimstone Crags, and it seems like he wasn't far off.
  • Lean and Mean: Nine feet tall and has the ideal slim body for the job.
  • Light Is Not Good: Decked out in his own version of the Auric Tesla armor, which was already golden in coloration.
  • Lizard Folk: Under the helmet, Yharim is in fact a reptilian, if Wordof God is to be believed.
  • Mad Scientist: He's mentioned several times to conduct many scientific experiments. He created the nanomachines that caused the Plague, tried cloning Yharon to make the Bumblebirbs, utilized a combination of magic and technology to create clones of Calamitas, and is implied to have made Yharim's Stimulants, a potent buff consumable. That's not getting into his actual armor of choice, which is a Powered Armor variant of the Auric Tesla armornote .
  • One-Hit Kill: Amidias foreshadows that he may specialize in this for his battle.
    Amidias: Lord Yharim possesses god-like strength. He may not even fight you at his fullest power, which is fortunate for you. His attacks may just kill you in one hit, so be careful.
  • The Plague: He created a version of this by making virulent nanomachines that would rot away at the target while using its life force to sustain itself. While he tried to contain it, they eventually got released, with disastrous consequences.
  • Powered Armor: Wears a mechanized version of the Auric Tesla armor.
  • Roaring Rampage of Revenge: Right after Yharon saved him from being immolated, his next move was to use Yharon's power to annihilate all the leaders of the Jungle and take over.
  • Summon Bigger Fish: His new solution to most of his problems is to throw the Devourer at it, which is odd considering that he's canonically many times more powerful than the cosmic serpent.
  • The Unfought: While he is intended to be a Final Boss, currently he is nowhere to be found besides in the lore.
  • World's Strongest Man: If Supreme Calamitas' words are taken as the truth, Yharim has yet to lose a single battle.
    • However, according to Amidias, this is a lie - Providence supposedly defeated Yharim and his forces a long time ago. However, she was forced to expend nearly all of her energy to do so.

    Goozma 
https://static.tvtropes.org/pmwiki/pub/images/goozma_7.png
Goozma's most recent sprite.
A mysterious cosmic entity of chaos and destruction, planned to serve as one of the two planned Superbosses.

Not to be confused with ya boy, Guzma.


    Xeroc 
A cosmic entity who wields power beyond that of gods, and is also said to be the creator and observer of the Calamity world. The Xeroc Armor is supposedly built using fragments of his body, but the myth has long since been up in the air. He is also the mysterious entity that oversees the player when they activate the Boss Rush.

He's also slated to be the second and final Superboss, meant to be fought after Goozma.


Town NPCs

    Cirrus, the Drunk Princess 
"Oh yeah now you're drinking the good stuff! Do you like it? I created the recipe by mixing fairy dust, crystals, and other magical crap."
https://static.tvtropes.org/pmwiki/pub/images/drunk_princess_0.png
A...drunk princess that'll move in if the player has Fabsol's Vodka in their inventory. Sells a number of helpful items, most prominently consumable alcohols that provide numerous buffs.
  • Author Avatar: She is the self-insert of the lead developer, Fabsol, who has been known to get drunk a lot on several occasions.
  • Booze-Based Buff: Vanilla Terraria already has one as the trope page's image, but she sells more kinds of alcohols which add even more of these buffs. To make things even better, each alcohol gives a different type of buff that's exclusive to that alcohol.
  • Buxom Is Better: Defied. She'll be happy to tell you that they cause back pain.
  • Double Entendre: Her quotes consist of a lot of sexual lines and innuendos. Fitting, since she's usually found drunk.
  • Easter Egg: If you talk to her during a blood moon, there's a chance that she will randomly damage you for half your max HP.
  • Fricking Laser Beams: When threatened, she'll defend herself with ricocheting rays of light that strike enemies and continue damaging for a short duration afterwards. This attack bears a striking resemblance to the beams used by the Fabstaff weapon, which is likely intentional.
  • Power at a Price:
    • Her Alcohols in a nutshell. They can provide a variety of benefits that no other consumable can provide, but will always have some kind of penalty that comes with it, most commonly reduced life regeneration.
      • Drinking more than two Alcohols will also give the player alcohol poisoning, which drains their HP rapidly, the rate of which increases the more Alcohols over two the player has ingested.
    • The Odd Mushroom. While it boosts all damage by a whopping 50%, it also has some...bizarre effects on the player's vision. To be specific, it causes all bosses, minions, and projectiles to get the Expert Brain of Cthulhu's hallucination effect, bathes all entities in warping rainbow-colored light, and produces a heat distortion effect over the entire screen.
  • Status Buff: She sells four different types of candles (Weightless, Vigorous, Resilient, Spiteful) for a hefty price. Said candles provide potent and exclusive buffs to anyone standing near them.

    Permafrost, the Archmage 
"I deeply appreciate you rescuing me from being trapped within my frozen castle.... It's been many, many years..."
https://static.tvtropes.org/pmwiki/pub/images/archmage.png
A brilliant mage who revolutionized magic with his work, Permafrost eventually withdrew into the mountains after being enlisted in the army and witnessing the horror that his magical advancements caused when used for war. Living in solitude in an ice castle atop a mountain, Permafrost's vast magical wisdom attracted many knowledge seekers, but he rarely shared his wisdom for fear that it would be misused again. When he refused to teach Yharim, the Tyrant trapped him within his own castle and forcibly transformed into Cryogen. He moves in after you defeat Cryogen and free him. Sells a number of ice-related weapons and items.
  • The Archmage: His countless advancements in magic led many to see him as the greatest wizard to exist. Bonus points for having "Archmage" as a title too.
  • An Ice Person: The archmage of ice who sells ice-related items, and uses ice blasts to defend himself.
  • And I Must Scream: Was sealed inside Cryogen for many years.
  • Anti-Frustration Features: One of the items he sells is Enchanted Metal, which can be used to craft the Mechanical Boss summons. This means that after defeating Cryogen, players don't have to farm any of the materials for the summons as long as they can afford some Enchanted Metal (admittedly though, it's quite expensivenote ).
  • Hidden Depths: The reason he was into ice magic is because...
    "Why ice magic, you ask? Well, my parents were both pyromaniacs..."
  • Keeper of Forbidden Knowledge: After learning of the horrific ways his magical research was being used, Permafrost withdrew from the world and stored his family's vast storage of magical literature in a hidden ice castle.
  • Last of His Kind: He states that there used to be Archmages of other elements, but he's unsure where they are now and if they are still alive by this point.
  • Living Lie Detector: Visits from thousands of knowledge seekers have given him the ability to discern a person's motives from a single look. This is the reason why he saw through and rejected Yharim on sight.
  • Really 700 Years Old: He claims to be even older than the Dryad, who herself also qualifies for this trope.
    Amidias, the Sea King 
"Is this... what the world is like now? It seems so much more lifeless than when I saw it when I disappeared."
https://static.tvtropes.org/pmwiki/pub/images/sea_king_0.png
Former king of a rich undersea kingdom, Amidias once harbored an insatiable curiosity for the world above the waves. However, after a traumatic incident, he opted to rule his people from the depths, keeping them away from the dangers of the surface. When Yharim sought him out for his aid in summoning the Moon Lord, he firmly refused - only for Calamitas to incinerate the entire ocean as his punishment, taking his kingdom with it. The Sunken Sea is all that remains of his lost empire, and it now serves as Amidias' final sanctuary.

He can be found as an NPC after killing the Giant Clam miniboss in the Sunken Sea, upon which he will join the player. In addition to selling weapons, clicking his Help option will grant the player a potent buff that grants unlimited underwater breathing until the player is hit or the duration runs out, even in the Abyss.


  • Clam Trap: Throws Snap Clams at enemies, which latch onto them for constant damage.
  • Fish People: A variant; he's an anthropomorphic leafy seadragon.
  • Fluffy Tamer: Duke Fishron's lore item suggests that Amidias tamed it and made it his companion. However, the Duke fled to the ocean once Calamitas was ordered to incinerate its former home.
  • Mister Seahorse: Naturally, because he's an actual seahorse.
    "Why do you ask if it's the males who carry their young? Don't your males carry their young?"
  • The Sleepless: Not needing sleep is part of his nature.
  • Mr. Exposition: Talking to him for long enough reveals a lot about the world's lore, as well as countless hints and notes about the bosses themselves.
  • Would Hurt a Child: He really dislikes the Angler, to the point he seems eager to throw him into the Sulphurous Sea.
    "Meet me at [Name of Angler]'s house at night. We're going to throw him to the Trashers."

Story Characters

    Braelor 
A heroic man blessed with unparalleled strength and chivalry. As word of his feats spread throughout the land, the ruling party of the time sought to recruit him in order to maintain control over the masses. Throughout all the attempts to win him over, the only successful one was when the ruling party fabricated a story about how his hometown was about to get destroyed by an enemy army - a story that was almost instantly disproven by Statis. Now convinced of the kingdom's treachery, Braelor became the mighty figurehead of a growing rebellion. His rebellion easily halted all attempts to stop them and were about to seize the kingdom from its corrupt owners. However, what they didn't expect was for a far stronger enemy to overthrow them first, before turning his attention towards their rebellion...

He was the original user of the Tarragon Armor, a mystic armor blessed with incredible endurance and regenerative abilities.


  • Healing Factor: He was the original owner of the Tarragon armor, which granted him this. Blessed by the gods with unmatched endurance, its metal grew like a living being to mend its injuries and draws upon the energy of the planet to protect and heal its user. It's not too hard to imagine how Braelor fended off the onslaught of the Jungle Tyrant's forces for years on end.
  • Heroic Second Wind: Silva's appearance encouraged Braelor and Statis to head into battle in an attempt to strike down Yharim himself. Unfortunately, they were soundly defeated, and Silva soon followed.
  • La Résistance: He led one against the rulers before Yharim, then against Yharim himself. While he was on the verge of overthrowing the first rulers, Yharim beat him to it - before doing the same to Braelor's rebellion.
  • Posthumous Character: By the time the player arrives, he was already killed by one of Draedon's mechs.
  • Precursor Heroes: Was one of them before the player, alongside Statis.
  • Super Strength: Braelor was born with strength that can only be called herculean. As a child, he was already accomplishing feats that grown men would consider impressive.
  • The Leader: A combination of incredible bravery, overwhelming charisma and immense strength let him impress the entire kingdom (save for the jealous rulers) and lead his rebellion to what would have been a solid victory if Yharim hadn't intervened.
  • True Companions: Upon encountering Statis, Braelor became the first person he could truly call a friend.
    Statis 
A prodigal ninja raised as the final legacy of a secret clan once they realized that their clan was all but doomed to fall. Honed to a lethal edge over years of training, Statis made his escape once the Jungle rulers' armies came to annihilate the clan, taking out a massive swath of them in the process. Living in the mountains and making a reputation for himself as a bringer of silent death, he eventually found a purpose in assisting Braelor's rebellion against the rulers of his homeland, and later against the Jungle Tyrant himself.

The Statigel Armor was an attempt to replicate his clan's traditional armor, but since his clan was totally wiped out, the replication only had a fraction of the original's power.


  • Heroic Second Wind: Silva's appearance encouraged Braelor and Statis to head into battle in an attempt to strike down Yharim himself. Unfortunately, they were soundly defeated, and Silva soon followed.
  • Ironic Death: The one he eventually died to was none other than Signus, who was the origin of his clan's techniques, and an assassin himself.
  • Knife Nut: Knives were supposedly his weapon of choice, and he had been gifted a particular kunai described to have phantom-like properties. This is heavily implied to be the Cosmic Kunai, meaning that the elders most likely obtained the weapon from Signus.
  • One-Man Army: When the old rulers of the jungle came to exterminate his clan, Statis single-handedly cut down nearly a quarter of their forces before they even realized it. Later, as he lived in the mountains, he was so dangerous that the mountains gained a reputation of being cursed.
  • Posthumous Character: By the time the player arrives, he had already died in an attempt on Yharim's life, at the hands of the then newly-recruited Signus.
  • Precursor Heroes: Was one of them before the player, alongside Braelor.
  • Super Empowering: The Statigel armor, which the founder of the clan originally used. It was made from the essence of the Slime God, and is infused with the entity's power.
  • True Companions: Became this with Braelor, who was the first person he could truly call a friend.
    Daedalus 
A brilliant craftsman and scientific genius who dedicated his life to uncovering the secrets of life itself. As he aged, he turned his attention towards the construction of a miracle machine that would allow him to cheat death. However, his city was soon attacked by Yharim's unstoppable forces, under the direction of the cyborg Draedon himself. Feeling guilty for abandoning his fellow citizens in favor of his life's work, Daedalus detonated his masterpiece and destroyed the city, taking most of Yharim's army with him.

The Cryonic Ore found underground was the alloy Daedalus used for his creations, although its power has deteriorated over time. It is the last remnant of Daedalus' craftsmanship, created from shrapnel embedded into the earth from the city's detonation.


  • Gadgeteer Genius: He was described as a genius in nearly all fields of science, able to design and build things ranging from architectural marvels to city-grade defenses. He even attempted to build a machine that would make him immortal - and, if Draedon hadn't intervened at the time, he almost certainly may have succeeded.
  • Godzilla Threshold: On the receiving end of this. You know that you're a genius when Draedon of all people decides that you're a threat to Yharim's conquest and must be eliminated, despite the fact that you're already well known as a pacifist.
  • Heroic Sacrifice: As Yharim's forces slaughtered everyone in his city, he felt guilty for abandoning them in his quest for immortality. Instead of finishing his immortality machine, which he had spent so much of his life on, Daedalus decided to honor his city by detonating his creation instead, taking Yharim's forces down with him.
  • Immortality Seeker: As he aged, he started looking for ways to cheat death so that he could live longer to uncover more of the universe's secrets. The end portion of his life was almost entirely taken up by his attempts to construct a machine that would let him do just that.
  • Posthumous Character: By the time the player's story begins, Daedalus has already been dead for centuries courtesy of his Heroic Sacrifice against Yharim's forces.
  • Seeker Archetype: He's obsessed with uncovering the mysteries of life and the universe, to the point where he seemed to care for little else.
  • Taking You with Me: Pulled this on Yharim's invasion force, obliterating the majority of his forces at the cost of his city, his immortality machine, and his life.
  • Technological Pacifist: Averted somewhat. He saw war as a waste of time and resources, and generally liked to avoid violence. That being said, he still did design weapons for his city - and said weapons made it all but unstoppable.
  • The Stoic: In addition to almost never showing any real emotion, he was also described as being free of all carnal desires and instinctual fears. He's even sometimes described as one of his own creations - a perfectly calibrated machine.
  • Too Powerful to Live: Despite his pacifism, a number of factions had tried (and failed) to acquire his knowledge, in hopes that they could destroy it before it was turned against them. However, when Draedon himself personally decides to field an army to kill him, however...
  • Undying Loyalty: Many factions had tried to recruit him, but he turned them all down out of sheer loyalty to his patron city.
    Silva 
The first nature spirit to ever exist, Silva was an immensely powerful Dryad who was connected to all plant life on Terraria. After being disturbed by Yharon's razing of the jungle, she sided with Braelor and Statis' rebellion, only for Calamitas to discover her and suffocate her in polluted sludge created by Draedon's experiments. The immortal but severely weakened Silva was then cast into the Abyss along with the pollution, where her soul now lingers, too weak to properly rise again.

The Silva Armor was the armor that Silva herself formerly wore, and is imbued with the life force of every plant on Terraria.


  • And I Must Scream: Clearly, being an immortal nature spirit didn't make suffocating in toxic sludge any less painful for her. Once she had been choked into a comatose state, she was cast into the abyss, where her severely weakened soul is now trapped.
  • Godzilla Threshold: She only shows herself when the environment has sustained immense damage. For example, when Yharim's uprising burned down most of the Jungle.
  • Green Thumb: She was the first nature spirit, after all. She had control of all of Terraria's plant life.
  • Healing Factor: The Silva Armor, which was originally her armor, draws upon the life force of all living flora to grant its user virtually unlimited vitality...so long as it has enough power to sustain it.
  • Nature Spirit
  • Physical Goddess: Being the original nature spirit linked to all plant life on Terraria, this is pretty much a given.
  • Posthumous Character: Well, less dead and more having her soul trapped in the Abyss without any hope of reforming.
  • The Worf Effect: She was established as a Physical God with immense wisdom and power. Then, Calamitas handily defeats her by exploiting her natural weaknesses, using nothing more than her own powers and Draedon's pollution. However, it was stated that Calamitas was on the verge of passing out from the sheer strain of restraining Silva.
