Glowbat

Tiny beast
Mundane; boon
Speed 5 ft., fly 30 ft

Regions: Lofty Mountains, Underland Realm (caves)

These small, fluffy white bats almost resemble tiny cotton balls with wings and are often seen in small groups of a dozen. They emit a faint bioluminescent glow that illuminates a space of 5 feet around them as the light spell. Because they do not venture very far below ground, the presence of glowbats usually indicates that there is either an entrance to a cave system or, when seen underground, an exit to the surface nearby.

Tamed glowbats are sometimes sold to spelunkers, miners, and adventurers alike for 50 gold. However, if not regularly fed bioluminescent fungi or insects, a glowbat stops glowing within 1 week. Upon resuming this diet, it takes 1 week for its glow to return.
