Blood Mirror

You create a glistening duplicate of yourself made from blood and dark reflection. The triggering attack or spell targets the duplicate instead of you. If the attack misses or the spell fails to affect the duplicate, the duplicate bursts and lashes back at the attacker.

The attacker must make a Wisdom saving throw. On a failed save, it takes 4d6 Psychic damage and 4d6 Necrotic damage. On a successful save, it takes half as much damage.

Once the duplicate bursts, the spell ends.
