The priest employs this spell to set up a wall of circling, razor-sharp blades. These whirl and flash around a central point, creating an immobile barrier. Any creature attempting to pass through the blade barrier suffers 8d8 points of damage. The plane of rotation of the blades can be horizontal, vertical, or in between. Creatures within the area of the barrier when it is invoked are entitled to a saving throw vs. spell. If this is successful, the blades are avoided and no damage is suffered; the creature escapes the area of the blade barrier by the shortest possible route. The barrier remains for three rounds for every experience level of the priest casting it. The barrier can cover an area from as small as 5 feet square to as large as 60 feet square.
Notes: Common for clerics (PHB).
