You infuse your next attack with a curse that causes horrible luck to befall its victim. The next time you hit a creature with an attack during this spell’s duration, your attack deals an extra 5d6 necrotic damage, and the target must succeed on a Wisdom saving throw or become cursed for the duration of the spell. The cursed target has disadvantage on all ability checks, and takes an extra 2d6 necrotic damage whenever you hit it with an attack.   If the target drops to 0 hit points before the spell ends, the curse’s power returns to you, eager to be afflicted on its next victim. The next time you hit a creature with an attack during this spell’s duration, it suffers the extra 5d6 necrotic damage and must succeed on the saving throw or become cursed by the spell. The spell ends if the new target succeeds on the saving throw.   A remove curse spell ends this effect on the target.
