"Screams echo around you..."
The Eater of Worlds is a pre-Hardmode giant Corruption-themed worm boss. 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.
The Crimson counterpart is the Brain of Cthulhu.
|| Worm Fodder
| is the achievement you earn for defeating the Eater of Worlds for the first time.
- In Expert mode, the Eater of Worlds shoots Vile Spit from its heads.
- Slime Mount will bounce and destroy Vile Spit if hit from atop, leaving player undamaged.
- 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 and less defense.
- Trying to summon the Eater of Worlds with Worm Food while another is still alive will not work and the item will not be consumed. Summoning additional Eater of Worlds by breaking additional Shadow Orbs doesn't work either.
- If the player leaves The Corruption, the Eater of Worlds will disappear (unless one manages to lure it into The Crimson). This also happens when breaking Shadow Orb outside of corruption biome (this is possible if surrounding corruption is converted by Purification Powder or Clentaminator) - the message for boss is displayed but nothing happens.
- 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 segment that becomes the head will not heal.
- 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. He will only be stuck for a few seconds though, since it can travel through blocks.
- When the Eater of Worlds spawns, it starts in a coiled state, and then unravels. Attacking it in this state will damage all its segments in that spot, which can kill it in seconds. This also applies to the Destroyer.
- When despawning, it travels straight up into the sky until it vanishes, unlike most bosses which travel underground.
- The Treasure Bag it drops in Expert mode will always contain the Worm Scarf.
For more elaborate strategies on defeating Eater of Worlds, including Weapon and Arena recommendations, see Guide:Eater of Worlds strategies.
- Weapons that pierce for multiple hits are effective, due to the Eater's large size and multiple parts.
- Additionally, weapons with a large area of effect such as the Medusa Head or Grenades can be used to great effect. Keep in mind grenades seem to deal much less damage against it in expert mode.
- The individual worms have a tendency to retreat into the ground when their heads are destroyed.
- If possible, try to aim for the head or tails of each section, as if they die first, they will not split into more.
- 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 each time, on average.
- During Hardmode, fighting the Eater of Worlds in the snow biome is an effective way to farm Amaroks as each individual segment has the 1:80 chance to drop it, each yoyo can sell for 5 depending on the modifier.
- The Vilethorn (a 20% chance drop from smashing Shadow Orbs) can be effective against the Eater of Worlds as it can pierce through walls and can hit multiple segments of the Eater of Worlds at once.
- Building a closed box (about 15x15) and using Water Bolt constantly is a great way to fight Eater of Worlds, however, you will need a decent amount of Health and Mana. Similar tactic can be used against Brain of Cthulhu.
- A player could try putting themself in a crevice in the Underground Corruption, then use a sword that deals more than 54 damage, and constantly swing it (this works because the Eater of Worlds will charge straight at the player and the head can be destroyed before it even touches them). Not recommended in expert mode.
