[[Category:]] Dark promise was a divine magic spell available to priests of Bane, the Black Lord. It put the victim under a type of geas that adversely affected his or her health each time the promise was broken. After Bane's supposed death in the Year of Shadows, 1358 DR, Cyric granted spells to Banite priests for a decade, so it was possible this spell could be found within the church of Cyric.
