Curse of Lycanthropy (Su): Any humanoid or giant hit by the bite attack of a drowwerebat in animal or hybrid form must succeed on a DC 15 Fortitude save or contract lycanthropy.

Poison (Ex): An opponent hit by a drow werebat's poisoned weapon must succeed on a DC 13 Fortitude save or fall unconscious. After 1 minute, the subject must succeed on another DC 13 Fortitude save or remain unconscious for 2d4 hours. A typical drow werebat carries 1d4-1 doses of drow knockout poison. Drow typically coat their arrows and crossbow bolts with this poison, but it can also be applied to a melee weapon. Drow have no special ability to apply poison safely, and since the effect of this poison is not magical, drow and other elves are susceptible to it.

Spell-Like Abilities: 1/day - dancing lights, darkness, faerie fire. Caster level equals drow werebat's class levels.

Alternate Form (Su): A drow werebat can assume the form of a dire bat or a bat-drow hybrid.

Bat Empathy (Ex): A drow werebat can communicate with bats and dire bats. It gains a +4 racial bonus on Charisma-based checks made against such creatures.

Blindsense (Ex): A drow werebat uses echolocation to pinpoint creatures within 40 feet. Opponents still have total concealment against the drow werebat unless it can actually see them.

Light Blindness: Abrupt exposure to bright light (such as sunlight or a daylight spell) blinds drow werebats in drow form for 1 round. On subsequent rounds, they are dazzled as long as they remain in the affected area.

Resistance: A drow werebat gains a +2 racial bonus on Will saves against spells and spell-like abilities.

Skills: A drow werebat in hybrid or bat form has a +4 racial bonus on Spot and Listen checks. These bonuses are lost if its blindsense is negated.

A drow werebat uses its flying ability to maximum advantage, swooping down to attack unsuspecting prey and then flying out of range.
