Curse

The target of this spell must make a wisdom saving throw against the caster's spell save DC. On a successful save the spell fails. On a failed save, a dark mist forms simultaneously around you and a foe of your choice, within sight. All damage the caster receives until the end of their next turn is in addition transferred to the target of this spell in the form of necrotic damage. The spell ends at the end of the caster's first turn after casting the spell, or if either the caster of the target are knocked unconscious.
