Special Abilities
Disease (Su) Demon Fever: Bite—injury; save F-DC 20; frequency 1/day; track physical, effect At the impaired state, penalties from the weakened state become permanent until victim receives heal; cure 2 consecutive saves. The save DC is Constitution-based.
Dream Haunting (Su) A night hag can visit the dreams evil-doers by using a special periapt known as a heartstone to become ethereal, then hovering over the creature. Once it does so, it rides on the victim's back until dawn. The sleeper suffers tormenting dreams and takes 1 point of Constitution drain upon awakening. Only another ethereal being can stop these nocturnal intrusions by confronting and defeating the night hag.
Heartstone (Su) All night hags carry a heartstone—a special gemstone worth at least 1,800 gp that is worn as a periapt. A heartstone's magic is fueled by the hag's spirit and proximity—once separated from its owner (or upon the hag's death), a heartstone retains its magic for only 24 hours before becoming a nonmagical gem again. The heartstone instantly cures any disease contracted by the holder. In addition, a heartstone provides a +2 resistance bonus on all saving throws (this bonus is included in the statistics block above). A night hag that loses this charm can no longer use etherealness or soul bind until it finds a replacement gemstone.
Terrifying murderesses and greedy soul brokers, night hags prey upon mortals while they're most vulnerable. Preferring to kill their prey slowly, haunting their dreams night after night, these hags trap the tormented souls of their victims within dark gems so they might be sold in the infernal markets of the outer planes. Night hags vary widely in appearance, standing between 5-1/2 and 7 feet tall, and weighing from 150 to 300 pounds.
