Cyclonic Blast

Cupping a child's top, you forcefully thrust your hand forward, simultaneously speaking hte final words of the spell's proscribed formula. Immediately thereafter, a blast of whirling wind issues forth from your outstretched fingers, sweeping up within it all who stands in its way.   You send a twisting torrent of wind, not unlike a tornado turned on its side, towards your enemies. A cyclonic blast deals 1d6 points of damage per caster level (maximum 15d6 points of damage) to all creatures and objects in the area. Objects bigger than Large take half damage. The cyclonic blast begins at your fingertips.   Creatures who fail their Reflex saving throw against a cyclonic blast are additionally in danger of being knocked back by the force of the wind. Treat this as a bull rush attack made with a +12 bonus on the Strength check. The cyclonic blast always moves with the opponent to push that target back the full distance allowed, and (unlike a normal bull rush) you can exceed your normal movement limit with a sufficiently high check result. Airborne creatures are treated as if they were one size category smaller for the purpose of resisting the bull rush.   If the damage caused to an interposing barrier by the blast shatters or breaks through it, the cyclonic blast can continue beyound the barrier if the spell's range permits; otherwise, it stops at the barrier just as any other spell effect does.   Focus: A child's spinning top.
 

You unleash a howling blast of spiraling wind in a 120-foot-long, 10-foot-wide line originating from you. Each creature in the area must make a Dexterity saving throw. On a failed save, a creature takes 6d6 bludgeoning damage and is pushed 30 feet directly away from you. On a successful save, the creature takes half damage and is not pushed.   Large or smaller objects and unattended items in the blast take damage normally and may be pushed at the DM’s discretion. Huge or larger objects take half damage and are not moved.   The blast can shatter barriers or objects in its path. If a barrier is destroyed by the damage, the blast continues beyond it, up to its full range. Otherwise, it stops at the barrier.   At Higher Levels. When you cast this spell using a higher level spell slot, increase the damage by 1d6 for each slot level above its base level.
