Bonebat

Bonebats were a skeletal undead created from the bodies of giant bats or several bat skeletons.

Behavior
Bonebats took a malicious delight in killing, though they would never attack other bonebats. If left uncommanded for extended periods of time they would attempt to temporarily leave their master's lair to go kill something. Such flights usually went on until the bonebat had killed at least two creatures, often of their own size or smaller. Out of all creatures a bonebat might encounter, bats were the one thing that they would go out of their way to kill.

Combat
Bonebats always approached their enemies silently. They attacked with a bite that could temporarily paralyze their victim. Being undead servants, the bonebat would obediently fight to the death if ordered to by their masters.

Ecology
Bonebats were generally created to serve as guardians, messengers, and even allies in battle. They were most commonly created by Red Wizards, members of the Arcane Brotherhood,, worshipers of Kiaransalee, as well as powerful undead such as liches, archliches, and vampires.

Bonebats were eternally bound to their creators, even if they had been slain, and couldn't be controlled by another.
