Animate Shadow

You bring to life the shadow of a creature you can see within range. The target must make a Wisdom saving throw: On a failed save, their shadow animates into a malevolent attacker. For the duration of the spell, the shadow stays attached to the target, sharing its space and constantly assailing the target, granting advantage on the next attack against it. In addition, the shadow deals 1d6 necrotic damage at the beginning of each of the target's turns. At the end of each turn, the target can attempt a Wisdom saving throw to dispel the shadow and end the effect.
