Corrosive Storm

You spray a storm of acidic gas out to fill a 40-foot cone originating from your space. Each creature in that cone must make a dexterity saving throw. On a failed save, the creature takes 8d6 acid damage. On a successful save, a target takes half the damage. The gas corrodes any easily susceptible objects that aren't being worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for each slot level above 3rd.
