Desert Wind

The caster throws a fistful of sand, which creates a brief sandstorm. Each creature in a 30-foot cone must make a Dexterity saving throw. A target takes 6d8 slashing damage on a failed save, or half as much damage on a successful one.

Walls or other cover may block the damage at the GM's discretion based on if the sand can touch the creature.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d8 for each slot level above 3rd.
