History VideoGame / TerrariaCalamity

* SealedEvilInACan: Calamity's elaborates on the Wall of Flesh (which was already considered to be this trope) by making it an alchemical monstrosity designed to contain the essences of slain Gods, preventing fallout like the Corruption or Crimson. The Hallow was one of said contained essences that broke free when the Wall was slain.

* TheVirus: The Astral Infection, a space-borne disease that spreads throughout the cosmos, infecting and consuming ''entire planets'' and their inhabitants, transfoming them into mutated vessels of the virus. To make matters worse, it can be spread by [[PlanetEater planet-devouring entities]] who take the infection into themselves. Upon defeating Wall of Flesh or Astrum Aureus, provided that the conditions are met, an Astral Meteor will strike the world and [[OhCrap infect a large chunk of it with the Astral Infection]], drastically changing the environment and allowing mutated alien creatures to spawn.

Once upon a time, in the land of VideoGame/{{Terraria}}, a mighty warrior named Yharim rose in rebellion against the Gods of the land, sparking a war that consumed the entire world for decades. His crusade scorched the earth, Gods and mortals alike perishing in his rage, until even he lost sight of the very things he fought for. Now, long after Yharim's disappearance from the ruined, cruel world, a lone Terrarian awakens to face its remnants…

* GameplayAndStorySegregation: Calamitas is said to be capable of ''[[PersonOfMassDestruction evaporating an entire ocean]]''. Even her strongest in-game form doesn't quite live up to the reputation.

* BadassArmy: Although not seen in the actual game, Yharim leads an army of soldiers who are armed to the teeth with both extraordinary magical armaments and technologically advanced equipment from Draedon. These soldiers carry out much of his will in his stead, purging the land of all who would oppose him and doing battle with literal deities.

* RageAgainstTheGods: Yharim rebelled against the Gods for their crimes against the old Draconic race, starting a bloody crusade that sets up most of the setting for when the player first arrives.

His crusade scorched the earth, Gods and mortals alike perishing in his rage, until even he lost sight of the very things he fought for. Now, long after Yharim's disappearance from the ruined, cruel world, a lone Terrarian awakens to face its remnants…

* BigBad: Yharim, Jungle Tyrant and Lord of the Cosmos. That said, [[TheUnfought it's not possible to fight him just yet]].

* BossRush: The item Terminus, which can found at the bottom of the Abyss, will summon an event where you have to fight all of the bosses in quick succession - made harder that the bosses are progressively buffed to an insane degree and have extroardinarily aggressive Malice AI, to the point where endgame players may struggle with bosses ''fought in pre-hardmode''. The order of the boss rush was determined by a community-made difficulty poll, so it doesn't follow the standard boss progression.

Once upon a time, in the land of VideoGame/{{Terraria}}, a mighty king named Yharim rose from the jungle and established an iron grip on the realm. Many years later, a young Terrarian enters the Jungle Tyrant's realm, and seeks to break free the land of Terraria from his control, [[WithThisHerring armed with only a Copper Shortsword, a Copper Pickaxe, and a Copper Axe]]. You are that Terrarian. Can you save Terraria?

* AcidPool: Calamity takes this up to eleven with the Sulphurous Sea. Once a normal ocean, years of being used as Yharim's body disposal and Draedon's waste dump did so much damage to it that it was irreparably transformed into an ocean of caustic acid. It's filled to the brim with dangerous creatures, and if you go too deep you'll enter [[UnderTheSea The Abyss]].
* ActualPacifist: Yharim's mother was one, though she carried the Astreal Defeat superweapon in case things got truly hairy. It didn't stop her family from being incinerated in the Underworld, leading to Yharim's StartOfDarkness.

%%* AlwaysSomeoneBetter: [[BigBad Yharim]] is this 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.

** After acquiring the Terratomere and slaying the Exo Mechs, many of the mod's swords can be combined to from the Exoblade, [[spoiler:Draedon's]] personal weapon. It is extremely powerful, being able to compete with even the [[PurposelyOverpowered Shadowspec weaponry]]. While other Exo weapons exist, the Exoblade was the original one.

* AndIMustScream: Cryogen is the archmage Permafrost, his ice fortress, and his magic sealed inside a living snowflake, for dozens, or even ''hundreds'' of years.

* BulletHell: Several Calamity bosses feature phases defined largely by a need to dodge large numbers of projectiles while keeping up the damage. None moreso than Supreme Calamitas, whose fight ''begins'' with the player doing nothing but dodging fireballs in a confined space for several seconds before Calamitas herself shows up, and multiple intermissions where she turns invulnerable and repeats this.

* CloneDegeneration:
** The first Calamitas you fight is a clone of the real Supreme Calamitas, and is far weaker than the boss they were cloned from.
** The Dragonfolly is a failed clone of Yharon, and is, of course, far weaker than the true Yharon.

* CombatTentacles: The Abyss-based Omega Blue Armor allows ''you'' to gain these, the set bonus giving you a number of AI-controlled tentacles that lash out at nearby targets to drain their life. When activating the armor's set bonus, they get even more aggressive.

* DarkerAndEdgier: Calamity's efforts to give Terraria's myriad bosses and biomes a cohesive lore resulted in something downright grimdark, taking place AfterTheEnd in a CrapsackWorld home to multiple fallen civilizations, faded gods, world-threatening infections, and a CosmicHorrorStory or two, all ruled by an all-powerful genocidal tyrant who already won and could crush the player like a bug if he weren't so close to the DespairEventHorizon himself.
* DealWithTheDevil: The Devourer of Gods struck a deal with Yharim in which he would be the latter's [[HiredGuns mercenary and pet for eternity]] (quite possibly hampering his OmnicidalManiac tendencies) in exchange for routinely receiving new powerful targets to feed on.

* DisproportionateRetribution: Back in the day, this seemed to be Yharim's favorite thing to do to people he doesn't agree with.
** Several oceans (probably the ones containing Cnidrion and the Desert Scourge) were incinerated because Amidias refused to participate in one Yharim's spells.
** Permafrost was turned into Cryogen because he refused to teach Yharim, knowing what would happen if he did.

* ElementalRockPaperScissors: Different elemental debuffs like fire, electricity, disease, and water will do significantly increased or decreased damage depending on what target they're affecting. Certain other effects will also amplify their damage, such as enemies in water taking massively increased electrical damage.

* EyeScream: The Twins from the vanilla game are the bio-mechanical watchers of the night, originally created as security using the souls ''extracted from human eyes.'' Even Yharim (who is heavily implied to have written the lore items) stated that these [[MechanicalAbomination creatures]] did not belong in this world; it's best to be rid of them.
* FireAndBrimstoneHell: In addition to the one in the base game, there's the Brimstone Crags, which is found in the lower-left corner of the world and is filled with incredibly deadly foes as well as cursed lava that can burn you through immunity. It was once the primary civilization of the underworld, but became desecrated and cursed beyond repair after Calamitas laid waste to it at Yharim's request. To be fair, [[AssholeVictim they kind of deserved it,]] especially after what they did to Calamitas' ancestors.

* FreudianExcuse: Implied with Yharim. Although it's officially stated that Yharim became the evil person he was because of someone's arrogance in the family (either himself or his brother), which led to, in no particular order, the incineration of his family, the loss of the Astreal Defeat (which the player later reforges), and the transformation of Yharon into a majestic beast, it could also be because of megalomania, since it's implied somewhat that the previous rulers of Terraria weren't any better than he was (being referred to as "tyrants," assuming the writing for Yharon's lore is from a neutral standpoint.)

* KarmaHoudini: The Lunatic Cultist is the only person known to have crossed [[DisproportionateRetribution Yharim]] and survived scot-free. Draedon also counts, as he's one of the only foes in Yharim's forces who can fight the player and escape a beatdown afterwards.
* LaserGuidedKarma: Nearly everyone Yharim hurt in his conquest left behind something that the player can equip and use to take on his forces.[[note]]Known accessories include a talisman for Amidias, what remains of Permafrost and his ice fortress, and a summoner accessory connected to Statis.[[/note]]
* LethalJokeItem:

* ManySpiritsInsideOfOne: In the Calamity lore, Plantera is a plant that was used as a vessel to house the spirits of those unfortunate enough to find their way down the Underground Jungle.
* MechanicalMonster: The Exo Mechs, 4 super-powerful robots designed by Draedon to surpass even gods in terms of power. You'll have to take on the four of them in a WolfpackBoss fight instead of Draedon himself.

* OutsideContextProblem: As of currently, the Hive Mind/Perforators, Aquatic Scourge, and Old Duke have nothing to do with the mod's main storyline.
* OverdrawnAtTheBloodBank: Implied with the bleed debuff from Soma Prime, causing enemies to lose 1500 health ''per second.''
* ThePlague: Yharim engineered a virus (referred to only by the trope name) and sent it into the jungle. Infected creatures would have their [[BodyHorror flesh rot away endlessly]] while Yharim would mechanize them into killing machines. Initially believed to only have infected the world's bees, WordOfGod confirmed that the plague hit everything, from slimes to ''Doctor Bones.'' Oh, and if you get hit by Plague Chargers, you contract the plague, too. Sweet dreams.

* PsychoPrototype: The Dragonfolly was a failed experiment to mass produce Yharon's species, but that doesn't stop it from being a post Moon Lord boss.

*** Supreme Calamitas and Draedon must be fought after Yharon, since their summons need Auric Ore and his Soul Fragments.

* TooAwesomeToUse: Calamity brings a couple examples.
** The Magnum is a pre-hardmode, all-class gun that uses Magnum Rounds, which are a very expensive ammunition type purchased from the Arms Dealer. While the ammo is limited and hard to come across, the Magnum deals absolutely colossal damage for how early you can get it and is a PercentDamageAttack on top of that, in addition to being able to be upgraded to the Lightning Hawk and Elephant Killer in Hardmode/Post Moon Lord respectively, which further raises its already massive damage. However, not only is its ammo hard to come by, every shot counts since it can only be fired 3 times per boss fight.
** The Hardmode Bazooka deals even higher damage than the aforementioned Magnum along with splash damage, but has slower shots, more expensive ammo, and a lower limit of 2 shots per fight.
** The post-Plantera Hydra fires a spray of exploding shotgun rounds that are capable of ''eclipsing'' the damage from the Elephant Killer and Bazooka at close range, except it can only be fired ''[[ItOnlyWorksOnce once]]'' per boss.

* UnexpectedGameplayChange: [[spoiler: Supreme Calamitas]] doesn't fight like a Terraria boss at all, instead locking you in an unbreakable arena box and turning invulnerable at designated points to spam projectiles at you that deal significant damage, turning the game into something resembling a ShootEmUp. These phases are even dubbed 'BulletHell' phases.

* WeCanRuleTogether: Yharim manages to communicate with the Devourer of Gods after he links several deaths to the worm, and offers a deal that essentially boils down to this. The Devourer accepted.
* WolfpackBoss: Draedon's Exo Mechs will attack you as a team, periodically tagging in and out over the course of the fight.
* WorfHadTheFlu:
** Why is Calamitas, one of Yharim's most trusted servants, fought well before the Moon Lord? Simple: [[spoiler:the one you fight before Plantera is a clone. The ''real'' Calamitas is ''waaaaaaay'' harder.]]
** The earliest Boss new to the mod, the [[SandWorm Desert Scourge]], wiped out an entire ocean kingdom in its backstory. By the time you fight it, though, it's much, much weaker as a result of being dried out and having to live in a desert. Fittingly, you fight a hydrated version called the Aquatic Scourge later in the game, and it's far stronger than its counterpart, being a early-mid hardmode boss
** The Elementals had power comparable to goddesses in their backstories. When you fight them, they're severely weakened due to a lack of faith causing them to fade away, with two of them being hardmode bosses and two being ''minibosses''.
** A full-power Providence is stated to be able to overpower just about anyone in the story, even ''Yharim'' himself. However, she can be defeated by the player thanks to her not being fully powered up yet, and since she's weakened from a prior skirmish with the Tyrant King.

A document detailing the most recent version of the lore can be found [[https://docs.google.com/document/d/14H0fmHigzvTxbQ1ipWOhD9bpN-49tN6cCs6Jb4QZRLw/mobilebasic here]]. Please note that the lore is now being reworked and will come in its next update, so some of the tropes listed below will be changed eventually.

* AlwaysSomeoneBetter:
** [[BigBad Yharim]] is this 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.

* SelfImposedChallenge:
** While Revengeance is practically needed to get the full experience of the mod, for those who want to push their skills to the absolute limit, fighting bosses with Death active (which provides virtually no tangible reward) should do the trick.
** There are some configuration options that add more challenge to the game, such as limiting curses on the Boss Rush, or an option to give bosses up to ''eleven times'' their original health.

* FakeBalance: Mostly averted. Despite complaints about self-centered balance, it's a mod that's meant to stand on its own, thus making it a NecessaryWeasel at worst.

** Similarly, Prismatic Lacewings spawn from the start of Hardmode instead of after Plantera, letting players take on the Empress of Light potentially right after coming home from the Wall of Flesh fight.

*** The Devourer of Gods is intended to be fought after all 3 of his Sentinels, since they drop the materials to make the Cosmic Worm. While it's possible to craft the Worm with an alternate recipe that does not need the Sentinels to be killed, this will result in any Sentinels you haven't killed spawning at full power during the midpoint of his fight.

** Purified Jam, dropped by the Slime God in Rev+. It drops a very small quantity of it (6-8 specifically) and it only drops it once per world '''and''' per character. However, if you're smart with it, the Jam can be used to turn around nearly any boss fight, as it grants you temporary ''GodMode'' for up to 10 seconds.
** The Magnum and the Bazooka. The Magnum is a pre-hardmode, all-class gun that uses Magnum Rounds, which are a very rare ammunition type dropped by bosses, but ''only on their first kill'' (however, it can also be purchased from the Arms Dealer for an extremely high price). While the ammo is limited and hard to come across, the Magnum deals absolutely colossal damage for how early you can get it and is a PercentDamageAttack against its favored target of organic enemies. In Hardmode, you can craft a Bazooka which basically functions the same way, except it uses Grenade Shells (dropped by bosses starting in Hardmode on their first kill or by buying from the Arms Dealer) and deals ''even higher damage'', especially against its preferred target of inorganic enemies[[note]]WordOfGod states that could do up to ''420,000'' damage to the Revengeance boss rush incarnation of the Devourer of Gods[[/note]]. As if that weren't enough, the Magnum can be upgraded further into the Lightning Hawk in hardmode and the Elephant Killer post-Moon Lord, which raises its effectiveness to ludicrous levels. Chances are that pulling one of these guns out during a boss fight will make it a hell of a lot easier, but with ammo normally being limited and being ''extremely'' expensive to buy, every shot counts - especially since they can only be fired a limited amount of times per boss fight (3 for the Magnum and its upgrades, and 2 for the Bazooka).
** The Hydra, a similar weapon you can get after Plantera, is even more of this. It uses Explosive Shotgun Shells as ammo, which are ''extremely'' expensive and only drop from bosses in minuscule quantities, and unlike its predecessors it can only fire ''once''' per boss fight. However, the Hydra is crazily powerful, converting each shell into a 15-round spray of high-velocity bullets that each deal percentage max HP damage to all enemy types. If you can land all the shots, the Hydra can deal nearly a ''quarter'' of a boss' HP per burst.

* AcidPool: Calamity takes this UpToEleven with the Sulphurous Sea. Once a normal ocean, years of being used as Yharim's body disposal and Draedon's waste dump did so much damage to it that it was irreparably transformed into an ocean of caustic acid. It's filled to the brim with dangerous creatures, and if you go too deep you'll enter [[UnderTheSea The Abyss]].

* EmpoweredBadassNormal: The player character goes from the mundane handicraft of vanilla Terraria to a warrior running on several types of {{Unobtainium}} and the abilities of fallen bosses. By the end of progression, they've at the very least killed a PhysicalGod and a serpent known for ''its'' ability to kill gods and absorb their power - [[UpToEleven and even then,]] the game isn't shy about telling you that compared to what's to come, ''those were the small fry.''

** The Charged Dart Blaster charges up the player's darts into fragile but high-velocity and extremely painful darts that split on impact. These shards can get stuck in the same target as the one the initial dart hit for maximum damage. Its upgrade, the Shredder, takes this UpToEleven to the point of severely lagging the game.

** A later patch added [[UpToEleven Deathmode]], toggled with the Death item which can be crafted at any Altar. It buffs enemy spawn rates and damage even further, allows bosses to spawn on their own, gives most biomes hazardous environmental effects, and pushes boss aggressiveness to its maximum by making them transfer into new phases faster (or just spawn in their most aggressive phases).

** Many items from the evil type the world didn't generate with are sold, and there's a sky island with said evil's legendary weapon.

** The Devourer of Gods' body segments are ignored by homing attacks and minions, preventing the body from absorbing their attacks as effectively.

** The Draedon Update adds Malice Mode, which enrages the boss AI while buffing their speed and damage, nerfs lifesteal, makes the Nurse unable to heal you while a boss is alive, and makes boss minions no longer drop hearts, among other things.

** The Draedon Update added Malice Mode which turns all of this UpToEleven, giving bosses new enraged AI while making them freakishly fast and damaging. In fact, unlike all of the modes listed above, the item that activates Malice explicitly states that the mode is not for the faint of heart.

** Malice is the ultimate example of this. It says something that having complete mastery of a boss fight, in-depth knowledge of their AI, and a ton of what would normally overpreparation isn't excessive to defeat a Malice boss on tier, but ''mandatory''.

** While Revengeance is practically needed to get the full experience of the mod, for those who want to push their skills to the absolute limit, fighting bosses with Death or Malice active (which provides virtually no tangible reward) should do the trick.

** Shortswords may also count. The mod brings the weak weapon type normally reserved for the very, very beginning of the game into its own endgame, culminating in the ''Terra Shiv'', followed by a ''post-Moon Lord shortsword'' which can obliterate targets with cursor-locked attacks, and followed by ''two more'' shortswords tied to progression bosses. All of this culminates in the post-Draedon Exo Gladius, which is comparable to the ''Exoblade'' in power. [[CatchPhrase "Don't underestimate the power of shivs"]] indeed.

* TheWikiRule: The official Wiki is found here [[https://calamitymod.wiki.gg/wiki/Calamity_Mod_Wiki]]

** While Revengeance is practically needed to get the full experience of the mod, for those who want to push their skills to the absolute limit, fighting bosses with Malice/Death/Defiled/Armageddon (or [[UptoEleven all of the above]]) should do the trick.

** Later patches added toggleable Defiled, Iron Heart, and Armageddon Modes. Defiled Mode severely reduces your wing time, and Iron Heart mode disables natural regen and all healing while capping how little damage you can take from an attack, making taking hits far more punishing. Armageddon Mode, however, turns you into a OneHitPointWonder while making bosses drop up to ''6 Treasure Bags'' if killed for the first time.

** Shortswords may also count. The mod brings the weak weapon type normally reserved for the very, very beginning of the game into its own endgame, culminating in the ''Terra Shiv'', followed by a ''post-Moon Lord shortsword'' which can obliterate targets with cursor-locked attacks, and followed by ''two more'' shortswords tied to progression bosses. All of this culminates in the post-Yharon Exo Gladius, which is comparable to the ''Exoblade'' in power. [[CatchPhrase "Don't underestimate the power of shivs"]] indeed.

* MiniMecha: The Flamsteed Ring allows the player to transform into one, named Andromeda. While in this form, they can turn into a jet for fast travel, attack with a lethal burst-fire gauss rifle, or strike down foes with a massive LaserBlade called Regicide.

* OneHitPointWonder: The toggleable Armageddon Mode turns you into this. Taking any hit while a boss is alive will instantly kill you, in exchange for making bosses drop up to 6 Treasure Bags when killed for the first time.

** The majority of the modded bosses can be fought at any time during their respective points of the game. Notable examples include the Leviathan/Aquatic Scourge being fightable at any stage of the game, the Lunar Event-tier Astrum Deus being available the moment Hardmode begins, and the Post-Moon Lord Dragonfolly being fightable ''before the Moon Lord itself''. There are a couple exceptions, though.

** Why is Calamitas, one of Yharim's most trusted servants, fought well before the Moon Lord? Simple: [[spoiler:the one you fight before Plantera is a clone. The ''real'' Calamitas is ''[[ThatOneBoss waaaaaaay]]'' harder.]]

* AdaptationExpansion: ''Calamity'' expands on the depreciated Thrower class from vanilla ''Terraria'' and turns it into the Rogue class, which revolves around a Stealth meter which builds up whenever not attacking. Building up stealth by spacing out attacks in order increases the damage of the weapons, and fully charging Stealth will empower the attack to devastate enemies.

** Death Mode buffs enemy spawn rates and damage even further, allows bosses to spawn on their own, gives most biomes hazardous environmental effects, and pushes boss aggressiveness to its maximum.
** Defiled mode reduces wing time to almost nothing, and gives bosses a 25% chance to land critical hits for triple damage, but doubles money drops and increases drop rates for rare items.
** Iron Heart mode disables all healing from potions and natural life regeneration while making all attacks always deal at least a portion of your maximum health[[note]]currently 40 + 10% of your max HP[[/note]].
** Armageddon mode makes you a OneHitPointWonder against bosses but makes bosses drop up to '''6''' Treasure bags upon death.
** The Draedon Update adds Malice Mode, which enrages the boss AI while buffing their speed and damage, nerfs lifesteal, makes the Nurse unable to heal you while a boss is alive, and makes boss minions no longer drop hearts, among other things, but allows the Bosses to drop Challenge Items guaranteed, which were previously either [[RareRandomDrop Rare Random Drops]] or dropped normally on Revengeance.

** [[spoiler:The first Calamitas you fight is a clone of the real Supreme Calamitas]], and is far weaker than the boss they were cloned from.

* TheComputerIsACheatingBastard: One of Providence's attacks will deal negative healing instead of actual damage. There is no cap on healing, [[LoopholeAbuse meaning that she is effectively launching an attack that bypasses immunity frames and is impossible to reduce]].

* ShoutOut: Hey, it wouldn't be ''Terraria'' without 'em.
** The Storm Ruler, a sword that can be made just before the fight against the Moon Lord, is a nod to a sword of the same name from ''VideoGame/DemonsSouls'' and ''VideoGame/DarkSoulsIII''.
** Gael's Greatsword, in name, tooltip ("Hand it over, that thing. Your dark soul."), and function (the sword shoots bloody skulls like the ones Gael shoots in his boss fight), is a reference to ''VideoGame/DarkSoulsIII''[='=]s Slave Knight Gael.
** One of the mod's developer weapons is simply [[MoreDakka Soma Prime]] from ''VideoGame/{{Warframe}}'', complete with special rounds that cause severe bleeding, true to the stats of the original weapon. A later update also added the Rubico Prime.
** The new difficulty introduced by the mod is outright called [[VideoGame/MetalGearRisingRevengeance Revengeance mode]]. You can find Sam's HF Murasama (deliberate mispelling retained) in an Underworld Chest (although it's locked until you beat Yharon unless you trigger an EasterEgg), and one of the swords craftable after killing Supreme Calamitas is called the Red Sun with the tooltip, "Over paradise." In addition, another broadsword that can be dropped by the Devourer of Gods is called Excelsus, named after the Metal Gear model that is the penultimate boss, and the tooltip for the accessory Draedon's Heart says "Nanomachines, son", an allusion to Senator Armstrong's [[MemeticMutation memetic quote]]. The boss health bar is even stylized like ''Revengeance[='=]s''.
** A developer weapon upgrade to the Arkhalis is called the Devil's Sunrise, a reference to the weapon of the same name from the ''VideoGame/EpicBattleFantasy'' series, which in turn, is a reference to the weapon of the same name from ''VideoGame/MapleStory''.
** The "Ice Barrage", a post-Moon Lord developer weapon, is named after and functions like the spell of the same name from ''VideoGame/RuneScape'', complete with the original sound effect, and the tooltip comes with the message for dying in ''[=RuneScape=]'' ("Oh dear, you are dead!"). The weapon also uses Blood Runes as ammunition, much like casting the spell in ''[=RuneScape=]''.
** The Karasawa laser rifle post-Moon Lord developer weapon is named after the same weapon from the ''VideoGame/ArmoredCore'' series, complete with insane firepower and heavy weight (as stated in the tooltip).
** The "Halibut Cannon" developer weapon is dedicated to the late [[Creator/TheCynicalBrit TotalBiscuit]], formerly known as [=TotalHalibut=], hence the appearance of a monocle and top hat on the weapon.
** Several to the ''Franchise/TouhouProject'' games:
*** Two obtainable developer weapons include the "Scarlet Devil", a dead ringer for Remilia's "Spear The Gungnir", which the tooltip even namedrops, and the "Dark Spark", an upgrade to the Last Prism that is a reference to Marisa's signature Master Spark, specifically its corrupted variation seen in ''VideoGame/TouhouKishinjouDoubleDealingCharacter''.
*** A later version also added the ''Resurrection Butterfly'', a summon weapon based on Yuyuko's spell card of the same name.
*** An even later version added a Bandit NPC who sometimes uses the quote "It's not stealing! I'm just borrowing it until I die!". For bonus points, one of her possible names is Marisa. Two other possible names for the bandit are Maribel and Hearn, likely a reference to Maribel Hearn.
*** The Hermit's Box of One Hundred Medicines, a Hardmode pet accessory dropped by the Wall of Flesh which summons a snake, is a reference to Kasen Ibaraki, who is also seen with a snake as one of her pets. The tooltip ("Eh? No way it's an oni.") references Kasen's constant attempts to deny her identity as an oni.
*** There's also a post-Moon Lord spiky ball called ''Hell's Sun'', referencing Utsuho- the tooltip even name drops one of Utsuho's spell cards, Subterranean Sun.
** Several to ''VideoGame/BloonsTowerDefense'':
*** The MOAB accessory, which gives you a smaller version of the series' namesake to jump around with.
*** The Monkey Darts that the Bandit sells are a reference to the Dart Monkeys, with the Stealth Strike throwing 3 darts like a Dart Monkey with the Triple Darts upgrade.
*** Additionally, the Glaive and Kylie are two weapons sold by the Bandit that resembles the likes of the those used by the Boomerang Monkey's upgrades.
** The Utensil Poker, an added drop from the Moon Lord, references the weapon of the same name from ''VideoGame/ChickenInvaders''.
** One of the Ravager's drops, the Spikecrag Staff, summons Spikecrags that are a reference to the Spikerocks in ''VideoGame/PlantsVsZombies'', with them looking like Ravager-themed counterparts of the original plant.
** The Omega Blue armor, in name, appearance, and function, is a clever allusion to the ''ComicBook/XMen'' villain Omega Red, with CombatTentacles for a set bonus, which can drain HP from nearby enemies, although the armor also removes your regen stat entirely, a nod to Omega Red's PowerIncontinence.
** The Lion Heart broadsword sold by the Cyborg after the defeat of Polterghast is a reference to the gunblade of the same name from ''VideoGame/FinalFantasyVIII'' and ''VideoGame/FinalFantasyXIV'', complete with its sprite resembling the former game's incarnation, and its right click replicating the latter game's Superbolide skill by halving all damage taken.
** The Temporal Umbrella summons a magic hat that "carries your soul, bounded by a contract", according to the buff text, and mentions in the tooltip that "this could defeat the Mafia in a single blow", all references to ''VideoGame/AHatInTime''.
** The Triboluminescent Etomer summons [[Franchise/{{Pokemon}} a Rotom]], which even changes form based on the biome the player is currently in.

** The majority of the modded bosses can be fought at any time during their respective points of the game (Pre-Hardmode, Hardmode, and Post-Moon Lord). There are a couple exceptions, though.

*** Supreme Calamitas and Draedon must be fought after Yharon, since their summons needs Auric Ore and his Soul Fragments.
