"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 body segments 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 Worm must be killed in order to defeat the entire boss.

Fighting the Eater of Worlds is the only way to obtain Shadow Scales, which are required to craft the Nightmare Pickaxe, The Breaker, and Shadow Armor. Defeating the Eater of Worlds also produces usable quantities of Demonite Ore. Individual segments drop some of these when killed, with a larger bonus drop upon defeating the entire entity.

If your world generated Crimson instead of Corruption, this boss will be replaced by the Brain of Cthulhu. The Eater of Worlds is immune to the Poisoned, On Fire!, and Cursed Inferno debuffs.


[edit] Notes

  • Individual segments cannot survive on their own. Killing one segment, when that part only consisted of two segments, will kill both.
  • 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.
  • Like all Worms, the Eater of Worlds is immune to Lava.
  • The Eater of Worlds has a total of fifty body segments: 1 head, 48 body segments and 1 tail. Its total health is 7,485.
  • When a part is destroyed, if it results in another worm being made, the segment from the original that becomes a tail will fully recover. The head from the new worm doesn't seem to recover any health, however. (This appears in Console.)

[edit] Tips

Player being "Loop Attacked" by the EoW
  • 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 (eg. Flails, Spears, Grenades, Spiky Balls, Vilethorn). The Harpoon is also effective, and is best used when being charged by its head.
  • During Hardmode, it is an effective means of farming Soul of Night. Every segment killed will give you 4-5 Souls.
  • 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.

[edit] Bugs

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 : Breaking a Shadow Orb with a Clentaminator in a corrupted chasm will display the boss summon message, but the worm won't appear.
Bug : On iOS eater of worlds may comes as a line of dungeon guardians occasionally.
Bug : Eater of worlds randomly sets you on fire and instanly kills you. Not sure what causes this.
Bug : Eater of worlds will some times die but leave no items like healing potions.
Bug : Sometimes in multiplayer, Eater of Worlds is still alive even if the text "Eater of Worlds is defeated!" was announced.
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.
