Acrid Spray

A blast of vitriolic spray cascades down in front of you. Each creature in a 30-foot cone must make a Dexterity saving throw. Each creature within 10 feet of you has disadvantage on this saving throw. A creature takes 10d4 acid damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 2d4 for each slot level above 3rd.
