A Bat is an aggressive Creature which live inside of Mine Entrances and appear by chance when Mining walls, when a Cave-In is imminent, or on the next level after a Mine-Down. The chance of Bats appearing is greater with higher levels of Madness. Bats are also spawned by Giant Bats.
Bats are aggressive; they will attack any pilgrim who wanders too close. A Bat will fly towards it's attacker and if it gets close enough it will unequip any item in the Neck slot and attach itself there. Once attached it will begin to Suck Blood. Bats suck between 3-4.5 Blood every couple of seconds. To remove an attached Bat, you must open your Equipment Window and ctrl+left-click the Bat in your Neck slot. This will not kill the Bat, so be prepared to fight it or Run away as it comes back to attach itself again. Stomp, with its AOE damage is a highly effective method of killing Bats. If another Bat has already attached to you, other Bats will use Bite.
A Bat will not detach, even if you are Knocked Out
, leading to potential multiple KO's if you are not quick to act!
A Bat, once killed, can be picked up and stored in your inventory as a Dead Bat. Butchering a Dead Bat will yield 1-3x Bat Fangs.
A Giant Bat is an aggressive Creature created by selecting a Dead Bat and right-clicking it on 8x Royal Jelly. Feeding Royal Jelly to dead Creatures adds a small amount of Insanity.
