Wrecking Fists

Supernatural

Level1

You gain Improved Unarmed Strike as a bonus feat, and your unarmed strikes don’t count as archaic weapons. Whenever you attack an opponent with your unarmed strikes as a standard action (or a full attack as a full action), as part of that action you can expend a 1st-level or higher spell slot before attempting the first attack roll to deal additional damage. If that attack hits, you deal an additional 2d6 damage per level of the spell slot expended, of the same damage type as your unarmed strike.
