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

Tips

 * 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 the player to stand next to the body, attacking every segment as it goes by. The player should be wary of the head looping back around.
 * If possible, try to aim for the head or tail of each section, as if they die first, the Eater will not split. Note that the head is far more vulnerable.
 * Using a Hook, it is possible to tank the Eater of Worlds by allowing the Eater to pass through the player and aiming for its head, quickly tearing the Eater 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 or Master mode. A quick way to escape is to have a bed to teleport to (using Recall Potions, Magic or Ice Mirror) 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 per kill.
 * If Vile Mushrooms run short, Vile Powder (for Worm Food) can be bought from the Dryad during a Blood Moon.
 * 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 can drop Amaroks, with each yoyo selling for a base value of.
 * In a Corrupt Ocean, it can drop 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 utilize this mechanic to keep the Eater of Worlds away from themselves without despawning it by moving in and out of the Corruption, watching for the boss's icon on the minimap to make sure it does not leave.
 * The Slimy Saddle tends to be very effective, allowing the player to bounce on the Eater's segments while dealing damage. This can be somewhat harder to pull off in, due to the Eater of World's Vile Spit But it can still be performed using a Mace or a Ball O' Hurt wich can be dropped by a Shadow Orb
 * Using a mace will block any Vile Spit from hitting the player when left-click is held down.
