Sandblast

A violent burst of sand and howling wind streams forth from your hand, extending outward in a cone.   Every creature and object within the cone takes 6d8 points of damage and is subjected to winds of hurricane force that blow directly away from you.   These winds blow away Medium or smaller creatures, knock down Large creatures, and check Huge or larger creatures.   (See Table 3-24: Wind Effects, page 95 of the Dungeon Master's Guide).   Any creature that succeeds on a Fortitude save takes half damage from the sandblast and ignores the wind effect.   Material Component: A handful of sand from the heart of a desert.
 

A violent burst of sand and howling wind streams forth from your hand, extending outward in a 60-foot Cone. Each creature in the cone must make a Constitution saving throw, taking 6d8 Slashing damage on a failure, or half as much on a success. A creature that fails its saving throw against these hurricane-force winds is pushed 30 feet away from you and knocked Prone if they are Medium or smaller, knocked Prone if they are Large, and cannot move toward you until the beginning of your next turn regardless of their size unless you move before then.   At Higher Levels. When you cast this spell using a higher level spell slot, increase the damage by 1d8 for each slot level above its base level.
