Acid rain

Acid rain appears in a location you choose within range. The area affected by the rain consists of up to ten 10-foot cubes, which you can arrange as you wish. Each cube must have at least one face adjacent to the face of another cube. Each creature in the area must make a Constitution saving throw. It takes 7d6 acid damage on a failed save, or half as much damage on a successful one.

The acid damages objects in the area and dissolve non metal objects that aren't being worn or carried. If you choose, plant life in the area is unaffected by this spell.

At higher levels: you can add 1 additional 10-foot cube to the area of the spell for each level higher than 5th.
