World Feeder

The World Feeder is a wormlike enemy that appears in The Corruption after defeating the Wall of Flesh. It sometimes drops a small amount of Cursed Flames on death. They are somewhat rare and are not as common as Devourers were before defeating the Wall of Flesh. They resemble a smaller Eater of Worlds. Killing this enemy will enable you to craft weapons such as the Dao of Pow, the Cursed Flames Book and even a Magical Harp, although alternatively, you can kill any Underground Corruption enemy, or even Goblins, to get the Soul of Night. Getting the Cursed Flame is the easiest to get from the World Feeder since it has a 100% chance of dropping the Cursed Flame.
