Cerebral Lash

You brandish the weapon used in the spell’s casting and make an attack with it against one creature within reach, which counts as magical for resistance purposes for this attack; on a hit, the target suffers the weapon attack’s normal effects. The target takes psychic damage equal to your spellcasting ability modifier for each attack they make and cannot hide from you until the end of your next turn.

This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1d6 psychic damage to the target on a hit. At 11th level, the psychic damage from the initial attack increases by 1d6 (2d6) and at 17th level (3d6).
