Writhing Remains

The Writhing Remains is a pet item that can be dropped by Eater of Worlds in Master mode at a chance. It summons a pet Eater of Worms. It acts similar to The Deactivated Probe, which is the Master mode pet of The Destroyer.

Trivia

 * The buff tooltip "May ruin several backyards" could possibly be a reference to worms digging many holes in backyards.
