You point your finger, and the creature that damaged you is momentarily surrounded by by shadowy mist. The creature must make a int saving throw. It takes 3d8 psychic damage on a failed save, or half as much damage on a successful one on a failed save the target is also blinded as shadowy images swarm through their mind
