Animate Shadow

You call up the shadow of one creature within range, making its shadow become a savage attacker.  The creature must make a Strength saving throw.  On a failed save, the creature takes 1d6 necrotic damage and is restrained by its shadow.  The creature takes this damage again at the start of each of its turns and can repeat the saving throw at the ends of each of its turns.  On a successful save, the creature takes half damage and is not restrained.  The shadow attempts to attack it again at the end of each of its turns.

At Higher Levels. When you cast this spell using a spell slots of 2nd-level or higher, the damage increases by 1d6 per spell level above 1st.
