The cleric employs this spell to set up a wall of circling, razor-sharp blades. These whirl and flash in endless movement around an immobile point. Any creature which attempts to pass through the blade barrier suffers 8-64 (8d8) hit points of damage in doing so. The barrier remains for 3 melee rounds for every level of experience of the cleric casting it. The barrier can cover any area from as small as 5’ square to as large as 2” square, 20’ x 20’ under ground, 60’ x 60’ outdoors.
