Effect Thick slabs of stone rise around you before tilting over. You deal 1d6 per 2 levels (rounded up) bludgeoning damage to all adjacent creatures (basic Reflex against your class DC or spell DC, whichever is higher). On a critical failure, the creature is also knocked Prone. At 3rd level, and every 2 levels thereafter, this damage increases by 1d6.
