Crushing Leap

You leap with the intention of harming any where you land. Using an Action, jump a distance equal to your regular jumping distance or height + (proficiency bonus x STR mod) and roll an attack roll against any foes in a 10ft radius. This deals Setback (pg. 249 DMG) bludgeoning damage to any creature in the vicinity if they're hit by the attack, and half damage if the attack roll misses. The ground in this area is now difficult terrain. This ability may be used twice per long rest without consequence, any use beyond gives the user a level of exhaustion.
