Pet Bat

The Pet Bat is summoned by consuming the Vial of Blood, an item that can be found in chests anywhere in the world except for Shadow Chests.

The Pet Bat buff is caused when the player uses the Vial of Blood item. The buff gives the player a Bat follower who deals damage to foes. Bat does 2-4 damage per hit.

The buff lasts until the player cancels the buff or dies.
