Special Abilities
Disease
Bite: A night hag can visit the dreams of chaotic or evil targets 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. 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.
