Acid Spray

You open your mouth and regurgitate a spray of acidic spittle. Each creature in a 20-foot cone must make a Dexterity 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.
