Draining Sand

You emit a blast hot and heavy sand from your hands. Each creature in a 30-foot cone must make a Constitution saving throw. On a failed save, a creature takes 4d8 necrotic damage and suffers 1 level of exhaustion. On a successful save, the creature takes half as much damage and does not suffer any levels of exhaustion.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d8 for each slot level above 4th.
