Acid Rain

A dark mist emits from your pointing finger to a point you choose within range and then expands with a deep rumble into a dark cloud of acid rain. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 acid damage on a failed save, or half as much damage on a successful one.

The acid rain cloud spreads around corners. It douses objects in the area that aren't being worn or carried with a corrosive acid.

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.
