The Eater of Worlds is one of the three pre-Hard Mode bosses, it is similar in behavior to the Devourer, but has a lot more health and many more segments. It also splits into smaller worms as it takes damage. It appears to be made out of multiple Eaters of Souls that are linked to each other. If you destroy a segment that is neither head nor tail, The Eater of Worlds splits at the spot that was destroyed and each half will continue fighting. However, upon splitting damage to each part remains; therefore, trying to maximize damage equally across the entire body will result in the most rapid kill.Terraria - Eater of Worlds(04:54)
The Eater of Worlds is either summoned in The Corruption with Worm Food or by destroying three Shadow Orbs. Either method may be repeated. Since patch 1.0.5, the Eater of Worlds can only be fought in the Corruption. Attempting to leave the Corruption will cause the Eater of Worlds to flee in a few seconds. There need to be at least 500 Ebonstone Blocks nearby in order to be considered inside a valid Corruption area.
Disclaimer: For the purposes of this guide, it is assumed that the player is using a new character in a new world, and would therefore not have access to late-game equipment, such as Molten Armor, a Fiery Greatsword, a Star Cannon, etc. Otherwise, this boss would be a piece of cake.
To defeat this boss, one must destroy every individual segment that makes up its body. The head has 65 and 0 defense, the body segments have 150 and 2 defense, and the tail has 220 and 4 defense. Each section must have a minimum of two body parts (a head and a tail). If either of those parts reach 0 health and there is no body segment to replace it, then both parts die. The Eater of Worlds begins with 50 segments.
Since this boss is composed of multiple segments that each have their own HP, weapons that can hit multiple enemies per attack are recommended. These include the Vilethorn, any kind of flail (such as the Ball O' Hurt) and a bow (preferably a Golden Bow or better) with Unholy Arrows, though a Gold Broadsword or better can be used if none of these are available. The Harpoon is also highly useful against this boss, since it's more than capable of striking multiple segments on his body at once if the player stands close enough.
Silver Armor or better is recommended, as well as having at least 200 . Bring along a few (Lesser) Healing Potions as well, as the head deals a massive 40 damage (minus armor), though the body segments deal only 15 damage by comparison.
The following optional Consumables may also be of some use during this boss battle, if you're willing to use them that is:
Because the head deals so much damage, it is strongly recommended that you avoid it at all costs, even if it means having to move through the boss's body segments (taking damage in the process). Also, it may be a good idea to aim for the head, as not only does it have less defense and HP than a body segment, but splitting the boss up by destroying body segments will only make it more difficult to dodge its attacks. (Focusing on the head should also increase the amount of loot dropped.) When the head is destroyed, the boss will stall for a bit, allowing you to take aim and fire at the new head. If the player is using one of the above recommended weapons, then it is possible for the player to stall the boss this way almost indefinitely, leading to a quick, easy kill.
It is ill advised to fight the Eater of Worlds inside a chasm, as not only can it strike with little warning, but it could also knock you to your death. You could use the Grappling Hook to cling onto a wall, though you should still avoid getting struck by the head as, again, it deals heavy damage to players.
Since this boss can only be fought in the Corruption, your arena will need to either be located in the Corruption, or be made out of enough Dirt Blocks covered with corrupted grass and/or Ebonstone Blocks (500 blocks should do the trick) for the game to determine that it lies within a valid corrupted area. The arena doesn't have to be very big (around 75 blocks is a nice width), though it should have a roughly flat surface at the bottom, and at least 2 rows of wooden platforms for avoiding the Eater of Worlds should it decide to swim along the surface of the bottom floor, or one of the rows of wooden platforms. If you'd like, you can dig some holes beneath your arena (and to the sides and above it if it was built underground) to more easily spot the Eater of Worlds before it attacks.
If you built your arena above ground, then you may have to deal with it becoming tangled up more often, as the boss doesn't have much earth to swim around in. However, if you built your arena partially or even fully underground, then the boss shouldn't tangle up as much, and can easily be set up for a quick kill (as mentioned before), though you will have to keep an eye on every side of your screen, as the boss can burst from the walls, or (if deep enough underground) even the ceiling.
- From patch 1.0.5 and onwards, the Eater of Worlds would flee after a while if the player wasn't in a corrupt area. Until patch 1.0.6, the player would get the message "Eater of Worlds was defeated.", but now the message says "Eater of Worlds flees."
- When summoned in the Underground corruption after WoF has been killed, it is (along with it's Hardmode counterpart The Destroyer) a great source of Souls of Night due to its many parts.
- This boss could possibly be a reference to the "Eater Of Worlds" from Stephen King's novel "Night Shift" from the first short story "Jerusalem's Lot".
- There is a bug where there can be 2, 3, or more Eater of Worlds will spawn at once if you use Worm Bait, then break 3 or more Shadow Orbs (3, 6, 9, etc.). Although, when you die, all but one of the eaters go away.
- A few players have come across a bug where they defeated the Eater of Worlds after they took away most of his body parts but then died. The players got all the items and coins he supposedly dropped though. Most of the claims could be confusion however, as defeated segments do drop some loot (including Demonite Ore and Shadow Scales) as the battle goes on.
- Another rare bug is that the boss will spawn as only a single segment, and nothing else. It will function the same as normal, just very ineffective at killing anyone.
- A Possible Bug may be that, when building over the Corruption, the boss will be summoned, as if displeased with the bridge, leading to much confusion and claims of griefing.
- One very specific bug may happen if the Eater of Worlds is fought in the Underground Jungle. Some of its segments may get "chained/fused" with a Man Eater and stand still.
- Another bug is that the boss will be summoned on world creation (i.e. Make a world then enter it). This is most likely caused by defeating a boss and then immediately creating the new world.
- Sometimes when a Meteorite landed and you exit the world and enter it the boss will be summoned.
- Another possible bug is when you've cut the Eater of Worlds into several segments and one kills you, that worm will disappear but the others will continue to fight (needs confirmation).
- A handful of players have come across a Strange Bug which causes the Eater Of Worlds to simply be defeated once they have died or left the Battle Area. However, upon return, no Items would Spawn, and the Monster's Corpse would be found, lying still on the floor. They were later able to Spawn the Boss again, at which point he dropped the correct loot.
- Now says "Eater of Worlds flees" when outside of corruption.
- No longer drops Shadow Armor and will flee if outside of corruption.
