Barbed Steel

You brandish the weapon used in the spell's casting and make a melee attack against a target within 5 feet of you. On a hit, the target suffers the attacks regular effects and you cause lacerating barbs to envelope the target until the start of your next turn. If the target takes reactions against you they suffer 1D8 Psychic damage and the spell ends.

This spell's damage increases when you reach certain levels. At 5th level, the melee attack deals an extra 1D8 Psychic damage on a hit, and the damage the target takes for a reaction against you increases to 2D8. Both damage rolls increase by 1D8 at 11th level (3D8) and at 17th level (4D8).
