"A horrible chill goes down your spine..." "Screams echo around you..."

The Eater of Worlds is a giant Corruption-themed worm boss (resembling a Devourer, but much larger) with eyes on every segment of its body. It is summoned using the Worm Food from within The Corruption, or by destroying 3 Shadow Orbs.

The Eater of Worlds is not a single target, but a string of 50 segments (1 head, 48 body, 1 tail) with individual life counters. When any inner segment is destroyed, it splits into multiple smaller worms, each with their own head and tail. Each section of the Eater must be killed in order to defeat the entire boss.

Defeating the Eater of Worlds is the only way to obtain Shadow Scale, as well as usable quantities of Demonite Ore. Individual segments drop some of these when killed, with a larger bonus drop upon defeating the entire entity. The Eater of Worlds is immune to the Poisoned, On Fire!, and Cursed Inferno debuffs.

If your world generated Crimson instead of Corruption, this boss will be replaced by the Brain of Cthulhu.


  • The different sections of the Eater of Worlds are not equivalent: A Head section will deal significantly more damage than the Body or Tail, but has far less life.
  • Trying to summon the Eater of Worlds with Worm Food while another is still alive will instantly kill the player. Summoning additional Eater of Worlds by breaking additional Shadow Orbs does work and will not kill the player.
  • If the player leaves The Corruption, the Eater of Worlds will disappear (unless one manages to lure it into the crimson which is unlikely).
  • Like all Worms, the Eater of Worlds is immune to Lava.
  • Individual segments cannot survive on their own. Killing one segment, when that part only consisted of two segments, will kill both.
  • When a part is destroyed, if it results in another worm being made, the segment that becomes the tail will fully recover. The head doesn't seem to recover any health (tested in Console and PC).

  • Farming the Eater of Worlds is one of the most effective ways of making money prior to Hardmode. Mid-game armor and weapons will make the fight easy, and selling its drops will yield 9 to 11 Gold Coin each time, on average.
  • Weapons that pierce for multiple hits are effective, due to the Eater's large size and multiple parts.
  • The individual worms have a tendency to retreat into the ground when their heads are destroyed.
  • During Hardmode, it is an effective means of farming Soul of Night. One Soul of Night can be dropped per segment, the percentage being the same as with other mobs.
  • During Hardmode, the Eater can be summoned to heal yourself when your health is low, even while fighting other bosses: Your equipment at this stage will kill segments quickly, and each segment drops more than enough hearts to not only offset their negligible damage, but also heal your character significantly, if not fully.
  • If possible, try to aim for the head or tails of each section, as if they die first, they will not split into more.


Bug.png Bug 1.1: Eater of Worlds might disappear even if you fight it in the middle of the corruption. This might happen if it goes too far away from the player.
Bug.png Bug : Breaking a Shadow Orb with a Clentaminator in a corrupted chasm will display the boss summon message, but the worm won't appear. This seems to be because he is outside of the Corruption, and so instantly despawns.
Bug.png Bug : Eater of Worlds randomly sets you on fire and instantly kills you. Not sure what causes this.
Bug.png Bug : Eater of Worlds will sometimes die randomly but leave no items like healing potions.
Bug.png Bug : Sometimes in multiplayer, Eater of Worlds is still alive even if the text "Eater of Worlds is defeated!" was announced.
Bug.png Bug : When killed, there will be between 2 and 7 head segments that deal 1000 Damage but only have 1 Health. This Bug has not been tested.
Bug.png Bug : Sometimes when the Eater of Worlds is spawned it will appear as if it is only his head and you are not able to damage other segments.This bug has been tested.
Bug.png Bug : Mobile only.png (iOS multiplayer) If the host will see "Eater of Worlds has been defeated!", others will see the message too, but there will be another Eater that spawns.
Bug.png Bug : Mobile only.png Eater of worlds may come as a line of Dungeon Guardians occasionally.
Bug.png Bug : Mobile only.png Sometimes on multiplayer the Eater will spawn randomly only visible to one player and will have no drops and also will damage the player.
Bug.png Bug : Mobile only.png Sometimes, while fighting EoW on Hardmode, hardmode ores will spawn as if you broke a Demon Altar.
Anomaly.png Anomaly: Mobile only.png (iOS) Each segment has a 33% chance to drop Rotten Chunk
Bug.png Bug : Mobile only.png When summoned with worm food, the Eater may dive straight down to the Underworld and immediately despawn.
Anomaly.png Anomaly: Mobile only.png When summoned by breaking 3 shadow orbs and teleporting away with a Magic Mirror, if you look in the minimap it will go up out of the ground and despawn. [Only tested on an Android device.]
Bug.png Bug : Mobile only.png when fighting Eater Of Worlds in a corruption that had been hitten by a meteor, the EoW head might turn into a meteor head and behave like a meteor head : It will follow you anywhere, it flies and the body follows it, it doesn't flee, it's annoying !
