Combat:
Heucuva try to use their polymorphing powers to trick their prey into thinking that they are nothing more than wandering monastic priests, and then attempt to infect their foes with their dreaded disease.  They hate priests and will break off attacks with other characters to attack any priest that attempts to use turning or spells to twart the heucuvas.

Disease: With each successful attack, the victim must pass a Fort save (DC 12) or be infected with a wasting disease.  The disease takes away one point of Strength and Constitution.  If a cure disease spell is not cast upon the victim before he loses all of his points, the victim will die.  Curing the disease replenishes any lost ability points.  

Undead: Heucuvas are immune to mind-influencing effects, poison, sleep, paralysis, and disease.  They are not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.  They are also immune to anything that requires a Fort save unless it also effects objects.

Polymorph: Three times a day a heucuva can polymorph themselves into a non-threatening shape.  Mostly, they attempt to appear as they did in life.  This effect only fools those that see normally, anyone with Darkvision or any other effect that allows them to see through magics see the heucuva as they really are.
