Bat demons are small, winged, aerial attackers reminiscent of the Blink type monsters from Diablo I. Unique amongst Diablo II monsters, bat demons hang from the ceiling (or thin air, on outdoor levels) and only drop down once a character is within their melee attack range. They can be targeted while on the ceiling, and can be hit by ranged attacks, or will drop down once a character is nearby. Bat demons are fond of flying away when they are low on hit points, and must be killed quickly, or pursued to their new perch.
