Spinning Crush 
Requirements You're wielding a loaded firearm or loaded crossbow.
You go into a vicious spin, smashing your weapon into those nearby and increasing your momentum by firing. All creatures adjacent to you take (4d6+@actor.abilities.str.mod) bludgeoning4d6 bludgeoning damage plus your Strength modifier; this increases to (6d6+@actor.abilities.str.mod) bludgeoning6d6 if your firearm has a striking rune, (8d6+@actor.abilities.str.mod) bludgeoning8d6 if it has a greater striking rune, and (10d6+@actor.abilities.str.mod) bludgeoning10d6 if it has a major striking rune. This ability does not apply other effects that increase damage with your firearm Strikes such as weapon specialization. Creatures affected by this attack must attempt a reflex save. A creature that fails its save is also pushed 10 feet directly away from you.
