Ice Bat

The Ice bat is a flying enemy, similar to the regular cave bat in behavior and appearance. Its icy nature causes stuck players to be inflicted with the Chilled debuff, and more rarely Frozen. It emits a very faint glow, which can sometimes reveal nearby caverns. Found in the Underground Snow biome. It is larger and more powerful than a cave bat, and may prove challenging for players without a gun or other ranged weapon.
