Game Breaker / Terraria

Terraria, being heavily item-based, is more than expected to have at least a few weapons that absolutely shatter the game.

In general

  • Players have always found ways to cheese bosses and events with minimal effort. In the order that they were patched, these include standing on meteorite, spikes, lava, and inside weak enemies.
  • The easiest way to cheese most invasion events is to have your home be an Elaborate Underground Base with a simple Lava Trapnote  ontop of it. Most invasions will always head towards your spawn point, but while they can break open doors, they can't break into trap doors leading down. As such, one can easily sit under their lava trap as the invasion goes on, with most mobs gleefully sacrificing themselves to the great Terraria Gods above while trying to get at you.
  • If you're fighting bosses or doing events, Heart and Star Statues completely break the game for anyone even moderately competent at dodging. By wiring them up to timers and spacing them apart, each one produces up to three of its respective drop, for a maximum of ten. That's free, infinite healing and mana which you can collect in a fraction of the time it takes to gulp down potions. Even the Final Boss will have a hard time wearing an agile player down.
  • The Party Girl's rockets can easily tear enemies a new one. While they require a lot of setup thanks to being a placeable block and not a weapon, they can completely trivialize a lot of things in the game, from beating the Dungeon Guardian in record time to oneshotting even the toughest of bosses.
  • Similarly, provided you can use it without blowing yourself up in the process, Dynamite is surprisingly effective against a good portion of the bosses, and a few post-hardmode ones as well. As one user demostrates, it's possible to kill the Wall of Flesh before the first night ends in record time with them.
  • Hoiking. A very, very versatile glitch. It's simple, but very effective. All you have to do is make a line of hammered slope blocks, and you have one of the fastest methods of moving items, mobs, and players around. You can use this to push certain items towards you, push mobs towards the previously mentioned Lava Trap, and push players across the map faster than even minecarts. Here's a video demonstrating several uses for item hoiks, and here's Yrimir killing Dungeon Guardian in record time because of it.
  • Bringing any hardmode items into a pre-hardmode world. Most hardmode items are able to kill pretty much everything pre-hardmode in one hit, and the armor is also good enough to stop you taking any hits (aside from Scratch Damage). Good when you just want to explore or build without worrying about dying.
  • The "Slimy Saddle Invincibility Machine" exploits the fact that stomping an enemy with the slime mount grants invincibility frames to the player and enemies. This machine simply consists of two training dummies placed under a ceiling with just enough space to enable the slime mount to continuously bounce on both dummies. This renders the player completely immune to all attacks (except those of the Moon Lord who uses unique invincibility frames for his attack).


  • The Celestial Shell, the result of combining the Sun Stone, Moon Stone, Moon Charm, and Neptune's Shell into one item. The situational Sun/Moon Stones become a permanent stat boost, Neptune's Shell provides a fishman form that removes the threat of drowning and allows normal movement in water, and the Moon Charm gives you a werewolf form at night that provides additional stat boosts. The thing that makes it a game breaker is that it stacks with the Celestial Stone, which has the exact same buffs minus the transformations, doubling the items' effect.
  • For yo-yo users, there's the Yoyo Bag. Made by combining the White String, Yoyo Glove and any Counterweight, the Yoyo Bag not only increases the range of the yoyo, but summons a second yoyo that circles around the first upon landing a successful strike. It also summons two counterweights that swing around the player, allowing it to cover the area around you or deal even further damage by getting up close to an enemy and striking them with both the yoyos and counterweights. It allows Yoyos to deal incredibly high, consistent damage from an utterly obscene distance, and it's obtainable as soon as you begin Hardmode if you're willing to hunt for the Skeleton Merchant. For added fun, try using Flasks of Ichor to perpetually soften up an opponent's defenses while attacking!


  • The Cosmic Car Key dropped by Martian Saucers. It allows you to summon a flying saucer mount... that has infinite flight time and moves faster than a sprinting player. Only a select few mounts have greater speed, and they either cannot fly or have specific conditions attached. It removes the need for an arena for pretty much every boss. It's also handy for fighting the gib-happy Dungeon Guardian, as it has the same top speed and moves faster diagonally. Getting it can be a pain, but the Martian Saucer is completely neutralized by a simple square of blocks around the player, so you can farm them safely as long as you have a yo-yo or something which can shoot through blocks.

Melee items

  • The Death Sickle, dropped by the Reapers during the Solar Eclipse, seems like just a moderately powerful melee weapon. But it also fires spinning sickle projectiles, which fly a short distance and hang around for several seconds, continuously hitting anything that walks into them... and they travel through blocks, something almost no player-usable weapons can do. This costs no mana, so you can spam glowing sickles as long as you like. With this thing, you can effortlessly slaughter most enemies while hiding behind a wall. It's especially nice for Plantera, because it spends a lot of time slowly moving through walls, allowing you to chop away at it in relative safety (unless you're in Expert Mode, where it has its own block-penetrating attack).
  • The Terra Blade. It's a very high damaging sword that shoots a just-as-high damaging sword beam. This makes it easily one of the best weapons in the game for melee players. In addition, it can be acquired fairly easily with some patience and luck even before fighting Plantera, despite being one of the five most powerful swords in the game. In the console version, it can be acquired even earlier, potentially after beating just one mechanical boss. Combined with a good modifier, it can easily carry you through most of the game.
  • Following the lead of both weapons above is the Flying Dragon sword. While only dropped by Betsy, who in turn only becomes available after defeating Golem, the above weapons are difficult (or at least very slow) to acquire before entering the Jungle Temple to gather Solar Tablets for grinding them, making all these weapons available at around the same timenote . Though slower and marginally weaker than the Terra Blade, each swing of the Flying Dragon releases a huge crescent Sword Beam capable of passing through walls and enemies alike. In addition to its wall-phasing properties giving it all the benefits of the Death Sickle with even better damage, the size of its projectiles makes it effortless to strike enemies at distance.
  • Vampire Knives fire off about five knives, which is great against bosses, because five shots is obviously better than one. However, the true prowess comes from its second effect: the knives heal you. When a knife hits an enemy, you regain 1-2 health. With the multiple knives and the fast firing rate, this weapon proves to be a great survival weapon, and is incredibly effective for any boss fightnote 
  • The Enchanted Sword/Arkhalis. They are two of the strongest pre hardmode swords, but what makes them a game breaker is how early and easily you can acquire them. They're found in enchanted sword shrines (a small cave with a one block wide tunnel that may lead all the way to the surface) or rarely even randomly underground. For players aware of them, they are very easy to identify, allowing you to potentially get a weapon to carry you through all of pre-hardmode on the first day! The only disadvantage is they aren't guaranteed to spawn in a world, but are still fairly probable, especially in medium and large worlds which have three and four shrines, respectively. Each ot which has a 1/3 chance of containing the true sword instead of a useless decoy.


  • For pre-Hardmode, the Minishark will tear apart just about anything. While it does cost a hefty 35 gold, which is hard to get early in the game, and you have to get something else gun-related, which requires a trip to the Corruption/Crimson as a bare minimum to even have access to it, the ends most certainly justify the means. It has a high fire rate, which absolutely shreds every pre-hard mode boss sans the Eater of Worlds and the Wall of Flesh. And it has a chance to not consume ammo, which is also very welcome considering the high fire rate.
  • The Star Cannon, while having a very big drawback of having to farm stars, which is incredibly slow, is definitely a good weapon. It fires stars at a very fast pace, which cause a lot of damage. It's definitely the best weapon to use against the Wall of Flesh, and if you have a good handful of stars left over, you can get some distance into hard mode with ease.
  • Upon beating the Wall of Flesh, you have a chance of getting the Clockwork Assault Rifle. This weapon is definitely what you'll need to survive the early days of Hard mode. It has the unique ability of firing three rounds a bullet, which saves you money. It also fires at the speed of the Minishark, which is also a welcome addition. In the right hands, this weapon can wreck half of the hard-mode bosses with ease. It's even better with Crystal Bullets, since it fires off three rounds of bullets that upon contact explode into several crystals that hurt enemies. You can use this to defeat even Plantera if you're good enough.
  • If you can manage to kill a Hallowed Mimic early on in Hardmode, you can get the Daedalus Stormbow, a bow which causes numerous arrows to rain from the sky from just one arrow. With an Endless Quiver, you can create an endless rain of death upon normal mooks. Against the Destroyer, equip Holy Arrows and watch the combined force of arrows and stars generated by the arrows shred him in under a minute. As long as you're good at dodging, you can have a full set of Hallowed armor in one night.
  • If you kill Destroyer before the other two mech bosses, you can guarantee you will have an easy time against his brothers. Because with his Souls of Might, you can turn the Minishark into a Megashark. The Megashark is a Minishark on steroids, having an even higher fire rate, even more damage, and does not consume ammo half of the time. With this weapon, you can destroy the Twins and Skeletron Prime with ease.


  • As soon as you enter Hardmode, Truffle Worms will begin spawning in Underground Mushroom Biomes. Should you have the mettle to challenge and defeat Duke Fishron before, for instance, the three Mechanical Bosses, you can effortlessly rip through whatever stands in your way with his Razorblade Typhoon. Each cast of the spell summons two rebounding discs with high speed, extremely good homing abilities, and unlimited piercing to fly about the battlefield slicing up anything unfortunate enough to get in the way - oh, and thanks to its size and wonky hitbox, the typhoons can clip through thin walls if you hug them as you fire. Because its homing and moderate turning radius allows it to hit one enemy and those around it repeatedly for its full duration, you can fire them about without fear of missing while still keeping your focus on evading attacks or using other weapons to pile on the damage. Slap on a mana-restoring accessory such as the Mana Flower or Magic Cuffs, and this tome can potentially carry you all the way through the Lunar Events and even the Final Boss.


  • While summoner builds have low defense armor, they easily make up for it by having their own mini-swat team of monsters at their command, making crowd control a really easy task, and very useful for dealing with the Goddamned Bats in the game. The best part is, most can be summoned at the mouse cursor. Because of this, they can easily cheese raids and bosses whose attacks don't go through walls. Set yourself up in a box, summon your minions, and watch them tear the enemies a new one while you kick back and rake in the loot.
    • A quirk of how summons work allows Summoners to be vastly more powerful then they at first appear. Summons use the stats of a their summoner to determine damage, but only at the moment they are summoned. This means a summoner can equip armor and accessories aimed at cranking their damage output to the max, summon their minions, and then swap out to more defensive gear. The only thing they have to keep the same is the +to max minions stat. This allows them to maximize their offense while still retaining relatively solid defenses with the only cost being the setup time upon starting or after dying.
