You send a twisting torrent of wind toward your enemies that deals 6 to 11 bludgeon damage per caster level to targets in its path. A successful Reflex save reduces the damage by half. If the target fails its Reflex save, it must make a Strength check or be knocked down. As a bolt this spell has double range. The spell also clears away all lingering effects in its path, such as clouds and walls of fire.
