Feat: Tidal Hands
With an emphatic gesture, you create waves that rush out from you in the shape of your hands. You either form two @Template[cone|distance:15]{15-foot cones} that don't overlap or you combine the hands into one @Template[cone|distance:30]. Each creature in a wave takes (floor((@actor.level -1)/2)+1)d8 bludgeoning damage with a Basic Reflex save against your class DC. If a creature critically fails, you also push that creature 5 feet.
Level (+2) The damage increases by 1d8.
