Deactivated Probe

The Deactivated Probe is a pet-summoning item that drops from The Destroyer in Master mode, with a chance to drop. It summons a short, small copy of The Destroyer as a pet that chases the player around. It is a miniature version of The Destroyer. It acts similar to The Eater of Worms, which is the Master mode pet of the Eater of Worlds.
