Brain

The Brain summons a pet Zombie when used. It grants the Pet Zombie buff that lasts until the player manually cancels it by right-clicking the buff's icon, or dies.

It can be obtained from Golden Chests.

Trivia

 * The animation of the zombie when you fly has the same look as the Spectre Boots animation while flying.
 * If there is a ranged enemy attacking you while mining, the zombie will block all the shots if it is standing in the area its shooting.
