Nocturnal cavern flyers of the underworld approach
The Giant Bat is a swift flying mammal encountered in the Cavern layer during Hardmode. Carrying 100 health and 16 defense, it flits erratically through darkness, delivering 45 contact damage in Classic, 90 in Expert, and 135 in Master. In Expert and Master modes, its bite has a chance to inflict the Feral Bite debuff, increasing damage dealt while causing random status ailments.
Trifold maps and bat bat harvesting
Because Giant Bats flutter with erratic momentum and high speed, wide-swinging broadswords or whips with large hitboxes swat them out of the air easily. Slaying Giant Bats offers a 1% chance to claim the Trifold Map, an Ankh Shield component that prevents the Confusion debuff. They also drop the Depth Meter at 1% and the vampiric Bat Bat club at 0.33%.
Trivia
- In Expert and Master modes, its bites can inflict Feral Bite, which causes confusion, darkness, and curse.
- Its Bat Bat drop heals the wielder slightly upon landing successful melee strikes.
