Eater of Worlds

The Eater of Worlds is a Pre-Hardmode Corruption-themed worm boss. It is summoned using the Worm Food from within The Corruption, or by destroying 3 Shadow Orbs that spawn in Corruption worlds.

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. The Eater of Worlds, like all worms, is immune to lava.

Defeating the Eater of Worlds is the only way to obtain Shadow Scales, and is one of the ways to obtain usable quantities of Demonite Ore. Individual segments drop some of these when killed, with a larger bonus drop upon defeating the entire entity. Defeating the Eater of Worlds allows the NPC to spawn.

The Eater of Worlds is the Corruption counterpart to the Crimson's Brain of Cthulhu. The Hardmode mechanical boss equivalent to the Eater of Worlds is The Destroyer.

Its Bestiary entry states: "Conceived from the bottomless malice of the Corruption, this mighty abyssal worm tunnels wildly to devour all in its path."

changes

 * In Expert mode, the Eater of Worlds periodically shoots Vile Spit projectiles from all body parts. These projectiles have a 5% (1/20) chance to inflict the Weak debuff onto the player for 10 minutes.
 * In Expert mode, the Eater of Worlds takes 80% less damage from most explosives.
 * This damage reduction does not seem to apply to Bouncy Bombs.
 * It has a ~20% speed increase compared to normal mode.
 * [[File:Desktop only.png]] When fought above the ground, the Eater of Worlds moves quicker and constantly fires vile spit at the player.

changes

 * All Expert mode changes apply.
 * In Master mode, the Eater of Worlds gains a 27.5% health increase. This brings its original Expert mode health of 10479 health up to 13361 health.
 * The Vile Spit debuff is increased from 10 minutes to 13 minutes.
 * It has a 30% speed increase compared to expert mode.

Tips

 * Using a mace will block any Vile Spit from hitting the player if the mace is kept swinging around the head with left-click.
 * Effective weapons include piercing or area-of-effect weapons, such as the Vilethorn, the Water Bolt, or Grenades, and fast melee weapons, such as the Falcon Blade and the Terragrim or Arkhalis.
 * Like other worm-types, once the Eater's head passes a given point, every body segment must follow. This allows standing next to it and attacking every segment as it goes by. Be careful to avoid the front end coming around again.
 * The Shark Tooth Necklace will eliminate most of the Eater's modest defense.
 * If possible, try to aim for the head or tail of each section, as if they die first, they will not split. The head is far more vulnerable.
 * Using a Hook, it is possible to position oneself in such a way that the head cannot get away before it is destroyed, quickly tearing the Eater of Worlds apart while tanking any damage through the hearts dropped by the destroyed head segments.
 * If fighting in a chasm, be wary of getting surrounded, which can lead to death very quickly, especially in Expert/master mode. A quick way to get out is to have a bed to teleport (using Recall Potions, Magic or Ice Mirror) to over the battle area.
 * Farming the Eater of Worlds is particularly profitable, being one of the most effective ways of making money prior to Hardmode.
 * With a defense of ~25 (Using the warding modifier if necessary), the danger of the Eater of Worlds is reduced to primarily its head.
 * Converting the Demonite Ore to Bars, selling its drops will yield an average of each time.
 * If Vile Mushrooms run short, Vile Powder (for Worm Food) can be bought from the Dryad during a Blood Moon.
 * In, the Eater of Worlds will likely take all the money a player drops upon death, as each segment counts as a separate NPC. This can be prevented by simply depositing all coins into a Piggy Bank, Safe, or Chest.
 * Since each segment can drop loot when killed, it can be a good source of Presents during Christmas, and Goodie Bags, Bloody Machete and Bladed Gloves during Halloween.
 * In Hardmode, it can provide other items as well:
 * It is a good way to farm for a Corruption Key/Mold, as every segment has a chance of dropping one.
 * In a Corrupt Snow Biome, it will drop Amaroks, as each individual segment can drop one, with each yoyo selling for a base value of.
 * Similarly, in a Corrupt Ocean it will yield Pirate Maps.
 * The Eater of Worlds will start to flee underground if the player leaves the Corruption biome, but will not immediately despawn. Players can use this fact to keep the boss away from them without despawning it by moving in and out of the Corruption, and watching for the boss's icon on the map to make sure it does not leave.
 * The Slimy Saddle tends to be very effective when fighting it letting you bounce on it while dealing damage, it is a little harder in expert/master mode because of Vile Spit. although still recommended (can be used for dodging)
 * When farming the Eater post-hardmode in a classic difficulty world (or in Journey mode with the difficulty slider at the corresponding level), exploding bullets are very effective, killing the Eater in under a minute.
 * If fighting above ground in either Expert or Master difficulty, a flail can be very useful in destroying the vile spit projectiles that this boss shoots out. Using this with a summon can be an easy "cheese" although it will take a while.

Trivia

 * The Eater of Worlds is the only boss that does not have its own AI.
 * It might spawn outside of map boundaries on rare occasions when breaking Shadow Orbs.
 * The Eater of Worlds is sometimes abbreviated as "EoW".
 * It is immune to many debuffs, whereas its counterpart, the Brain of Cthulhu, is only immune to Confused.
 * The Destroyer's bestiary entry mentions it being a replacement for the spine of Cthulhu. However, despite being the hardmode variant of the Eater of Worlds, the Eater of Worlds is not the original spine of Cthulhu.

History

 * Now has more segments, even more so in Expert Mode.
