Wall Of Silver

You create a wall of translucent silver energy that hums and vibrates at the slightest touch. Objects and nonevil creatures can pass through this wall without difficulty. However, spells and effects with the evil descriptor treat this barrier as a wall of force, which blocks line of effect. Evil creatures that pass through the wall take 3d6+(min(20,CASTERLEVEL)) points of damage and are blinded for 1 round. Creatures of any alignment that are particularly vulnerable to silver (such as those with damage reduction bypassed by silver, like devils or lycanthropes) instead take (min(15,CASTERLEVEL))d6 points of damage, are staggered for 1 round, and are permanently blinded. A creature that succeeds at a Will save reduces the damage by half and negates the blinding and staggering effects. If you create a wall of silver so that it appears where creatures are, each creature takes damage as if passing through the wall. Each such creature can avoid the wall (ending up on the side of its choice) and thus take no damage by succeeding at a Reflex save.
