The Creeper Heart is an item from the Witchery mod. This item is obtained, rarely, by slaying Creepers. The chance at which Creeper Hearts drop can be increased by using an Arthana. The Creeper Heart is useful for several recipes, mainly the Witches Robes, and the Frozen Heart. It can be shapelessly crafted into five gunpowder per heart.
Eating a Creeper Heart will cause a decently sized explosion around and on the player. This can be toggled in the config file.
A Creeper Heart can be used to buff a Treefyds health to 100, and its damage to about 4 damage.
