Animate Shadow

You bring to life the shadow of a creature you can see within range. The creature must succeed on a Wisdom saving throw or their shadow animates into a malevolent attacker. The shadow stays attached to the target, sharing it's space and constantly assailing it. For the duration of the spell, the target takes 1d6 Psychic damage at the beginning of each of its turns and all attack rolls made against this target have Advantage. At the end of each of its turns, the target repeats the save, ending the spell on itself on a success.

Using a Higher-Level Spell Slot. You can target one additional creature, and the damage increases by 1d6 for each spell slot level above 1.
