Tlokasazotz [Bat-Vampire]

Only one tlokasazotz exists: Itzcoatzin, king of a small jungle realm of temple-building folk. Usually he is an 8-foot winged bat-man with huge arm talons, but he can resume his birth shape, a cruel, regal man.

His god's gifts are many. Talons and fangs rip hard wood, copper and bronze (+1 to hit when the target's armor is made of them). His fiery breath fills a 10-foot sphere before him for 6d6 damage. Three times daily he may take human form for up to a turn. In either shape he casts as a 14th-level priest, using any spell available to specialty priests of the bat god or the lord of the dead but none of their other powers.

Weapons under +1 bounce off his fur, he regenerates a point of damage each round in any form, and keen ears give a 50% chance to detect invisible foes. Not undead, he cannot be turned and ignores holy water. His bite spreads lycanthropy, and one undisturbed round of drinking a victim's blood makes them a werebat automatically. These werebats cannot pass on the curse and thirst only at full moon, but their children are normal werebats.

Itzcoatzin fusses over his shapechanging subjects like an overprotective parent from a crumbling temple-palace staffed by werebats, flying out each night to feed on wild beasts and herds. He enjoys talk and often greets visitors in human form if their gifts please him.

Like a vampire bat he is a parasitic mammal who rarely kills, so the land suffers little. Without blood each day he loses a hit point daily along with regeneration and fire breath. He avoids human blood except to make werebats. Only word that someone is hurting his subjects sends him raging toward those responsible, wrecking everything along the way.
