Bestiary | Monsters | Night Hag | Special Abilities | Heartstone
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.
