Eater of Worlds

The Eater of Worlds is a pre-Hardmode Corruption-themed worm boss. It is summoned using Worm Food from within the Corruption and Underground Corruption, or by destroying 3 Shadow Orbs that spawn in Corruption-filled worlds. It can be summoned at any time of day. Do note that Eater of Worlds shoots vile spit in Expert and Master mode.
The Eater of Worlds is not a single target, but a string of segments with individual life counters. When any inner body 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.
On the versions, it has a total of 67 / segments, and is only immune to the Confused debuff.
On the versions, it has a total of 50 segments, and is immune to the Poisoned, Confused, Cursed Inferno, Shadowflame, On Fire!, and Venom debuffs.
Fighting the Eater of Worlds is the only way to obtain Shadow Scales, and it's one of the only ways to obtain usable quantities of Demonite Ore, both necessary for crafting a Nightmare Pickaxe. 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, and meteorites to land.
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.

== Notes ==
* If the player dies or leaves the Corruption, the Eater of Worlds will stop following the player and start burrowing into the ground until it despawns. Note that if the player goes to the Crimson, the Eater of Worlds will continue to chase the player.
* 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.
** Breaking multiple Shadow Orbs will still allow multiple Eaters of Worlds to spawn. Regardless of how many are summoned, only the last head alive will display the defeat message.
* Note that actually defeating the Eater of Worlds is not completely necessary to progress, as a certain amount of segments may drop the needed amount of materials.
** However, defeating the Eater of Worlds or Brain of Cthulhu is the only way to gain access to the and Meteorite .
* The different sections of the Eater of Worlds are not equivalent: the head section will deal significantly more damage than the body or tail, but also has the least defense.
**The reverse is true for its tail; it has more defense than the body or head, but also deals the least damage.
* Individual segments cannot survive on their own. Killing one segment, when that part had only consisted of two segments, will kill both, with both segments dropping loot.
* When the Eater of Worlds splits, the segment that becomes the tail will fully recover. The segment that becomes the head will not heal. Newly formed worms tend to retreat into the ground.
* Depending on where exactly the Eater of Worlds is summoned, it may get stuck underneath empty terrain such as a cave. It will only be stuck for a few seconds, however, since it can travel through blocks.
* The Eater of Worlds spawns in a coiled state and unravels from there. Attacking it with piercing weapons in this state will damage all its segments, which can kill it in seconds.
* The Eater of Worlds only takes 65% of the usual damage from Molotov Cocktails.
=== changes ===
* In Expert Mode, the Eater of Worlds is about 20% faster.
* It periodically shoots Vile Spit projectiles from all body parts. These projectiles have a chance to inflict the Weak debuff onto the player for 10 minutes.
** When fought above the ground, the Eater of Worlds moves quicker and constantly fires Vile Spit at the player.
* The Eater of Worlds takes 80% less damage from most explosives.
** This damage reduction does not seem to apply to Bouncy Bombs.
== Achievement ==
== Tips ==
* Effective weapons include piercing or area-of-effect weapons, such as the Vilethorn, the Water Bolt (), Spiky Balls, Grenades, , and fast melee weapons, such as the Falcon Blade and the or .
* 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.
* Killing the head of the Eater of Worlds causes its speed to drastically decrease, almost to a stop.
* 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.
* 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 or a Magic or Ice Mirror) above the battle area.
** It may be preferable to hollow out an area in the Corruption in advance, in order to avoid this situation.
* Farming the Eater of Worlds is particularly profitable, being one of the most effective ways of prior to Hardmode.
** Converting the Demonite Ore to bars and 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 Machetes, 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 , 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.
* Using a flail will block any Vile Spit from hitting the player when is held down. Alternatively, a whip would also work for it can sweep a large area clean of vile spit in a single whip.
*In versions 1.4.1 and higher the Blade of Grass is a great sword to take on the Eater of Worlds.
