Flaywind Burst

This spell produces a brief windstorm (approximately 70 mph), filled with scouring, supernatural grit that literally strips flesh.   In addition to the possible effects of the wind, creatures within the area of a flaywind burst spell take 1d6 points of damage per caster level (maximum 10d6) from the scouring sands.   A successful Reflex save halves this damage.   A creature within the area of flaywind burst must make a Fortitude save or experience the effects of the wind's force.   A Small or smaller creature is knocked down and rolled 1d4×10 feet, taking 1d4 points of nonlethal damage per 10 feet.   If flying, a Small or smaller creature is blown back 2d6×10 feet and takes 2d6 points of nonlethal damage.   Medium creatures are knocked prone, or if flying are blown back 1d6×10 feet.   Large or Huge creatures are unable to move forward against the force of the blast, or if flying are blown back 1d6×5 feet. Gargantuan or larger creatures can move normally within a flaywind burst.   Flaywind burst can't move a creature beyond its range.   In addition to the effects noted, flaywind burst can do anything else that a windstorm-force sandstorm would be expected to do, such as briefly obscure vision, heel over a boat, or blow Gases and vapors to the limit of its area.
 

This spell produces a brief windstorm of approximately 70 miles per hour, filled with scouring, supernatural grit that rips flesh from bone. Each creature in a 60-foot Cone must make a Dexterity saving throw, taking 8d6 Slashing damage on a failure, or half as much on a success.   A creature that fails its saving throw is also subject to the wind's full forces. A Small or smaller creature is pushed 1d4 x 10 feet away from you then knocked Prone, or 2d6 x 10 feet if flying. A Medium creature is knocked Prone, or if flying it is pushed back 1d6 x 10 feet. Large or Huge flying creatures are pushed 1d6 x 5 feet away from you. Creatures larger than Huge are not moved. Regardless of how far a creature is pushed, it will never be pushed more than 5 feet outside the cone of this spell.
