Excoriate

You choose a target and on a touch, pull the skin off their body, or at least make it look that way. Make a melee spell attack roll against the target. On a hit the target takes 3d6 psychic damage as the target's skin is peeled away at your touch. The target then makes a Wisdom saving throw. On a successful save the target is unaffected, on a failure the target receives the frightened condition. 

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
