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 Scales, 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.

Notes[edit | edit source]

  • In Expert Mode, the Eater of Worlds shoots Vile Spit similarly to a Corruptor.
  • 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).
  • There is a Hardmode Mechanical Boss equivalent of the Eater of Worlds, The Destroyer.
  • Depending on where exactly you summon him, he may get stuck underneath some empty terrain, such as a cave. His spawn location is relative to the player, not to the bottom of the map.

Tips[edit | edit source]

For more elaborate strategies on defeating Eater of Worlds, including Weapon and Arena recommendations, see Guide:Eater of Worlds strategies.

  • 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.
  • If possible, try to aim for the head or tails of each section, as if they die first, they will not split into more.
