Devourer

Devourers are large worms that reside in the Corruption. They follow the Worm AI.

Along with Eater of Souls, Devourers impede the player's progress through the Corruption and will often knock them into chasms. When there are multiple Eater of Souls and a Devourer on the screen, getting back out of the chasm can prove difficult, even with a Grappling Hook.

Destroying any part of the Devourer kills it. The best way of killing a Devourer is the same as killing any other worm, using weapons that can hit multiple enemies simultaneously like the Ball O' Hurt and Blade of Grass.

Drops
As with all worms, this is the drops for a single Segment. Destroying several Segments simultaneously (with Explosive Consumables) can yield multiple drops.
 * 3-8 Worm Teeth: 100% (1:1 chance)
 * 1-2 Rotten Chunks: 33.33% (1:3 chance)
