Claws of Graymalkin

As part using this spell, you must make a melee attack with a weapon against one creature within 5 feet, otherwise the spell fails. On a hit, the target suffers the attack’s normal effects, and it becomes sheathed in shadows until the start of your next turn. If the target makes an attack against you before then, it immediately takes 1d10 psychic damage, and the spell ends.

This spell’s damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d10 psychic damage to the target, and the damage the target takes for attacking you increases to 2d10. Both damage rolls increase by 1d10 at 11th level and 17th level.
