Caustic Explosion

Acid erupts from your space in all directions. Each creature within 30 feet of you must make a Dexterity saving throw, taking 6d10 acid damage on a failure, or half as much damage on a success. Objects that aren’t being worn or carried in the area also take this damage. For the next two rounds, creatures that failed their saving throws take 3d10 acid damage at the start of their turns, unless the acid is dispelled.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the damage increases by 1d10 for each slot level about 7th.
