You whip up a cloud of stinging and blinding sands in a 30-foot radius burst centered on a point you can see within range. The sands and wind go around corners. Creatures attempting to make ranged attacks out of or into the winds receive disadvantage. The tiny but sharp grains of sand blind and impair people within. Any creatures in the area that fail a Strength saving throw when the cloud appears and the start of their turn are blinded for a round, and for every one foot they move, it counts as three feet. If they succeed, they are not blinded and their speed is only halved. In addition, the area is lightly obscured. Finally, the slashing sands deal 4d8 piercing damage per round at the start of your turn and the round they appear.
