Shaitan Earthblast

While using the Shaitan Style feat, as a standard action, you can spend two Elemental Fist (Advanced Player's Guide 158) attempts to unleash a 20-foot column of acid that has a 5-foot radius and erupts from a point of origin within 30 feet of you. Creatures caught in the column take your unarmed strike damage plus the acid damage from your Elemental Fist and are staggered for 1 round. A successful Reflex save (DC 10 + 1/2 your character level + your Wis modifier) reduces the damage by half and prevents a target from being staggered.
