Acid Cloud

You summon a green seethrough ghost head of a bog body from the ground. It rises up about 20 feet in the air and vormits cloud of acid and dacayed body parts on the creatures beneath.

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 spreads around corners.

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.
