Erratic fluttering pests through subterranean tunnels
Cave Bats are notorious subterranean pests inhabiting the Underground and Cavern layers. Endowed with 16 health and 2 defense, they flutter erratically through unlit tunnels to inflict 13 contact damage (26 in Expert and 39 in Master). In Expert and Master modes, their bites carry the Feral Bite debuff, causing erratic stat drops and confusion.
Extracting chain knives and depth meters from cavern shadows
Their small hitbox and winding flight trajectories make Cave Bats challenging to hit with precision arrows, making swinging broadswords or yo-yos superior defensive choices. Slain Cave Bats drop the Depth Meter at a 1% rate, the Chain Knife flail at 0.4%, and the Don Starve crossover Bat Bat at 0.33%.
Trivia
- Cave Bats can inflict Feral Bite in higher difficulties, briefly swapping control keys or applying random debuffs.
