Acid Rain

You create a caustic downpour of acidic rain in a 15-foot-radius, 60-foot high cylinder centered on a point within range. When a creature enters the area for the first time on its turn or starts its turn there, it must make a Constitution saving throw, taking 4d8 acid damage on a failed save or half as much on a successful one. On each of your turns for the duration, you can use a bonus action to move the cylinder up to 10 feet in a horizontal line.

The acid damages non-magical objects in its area that are not 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 1d8 and you can move the cylinder an additional 5 feet for each slot level above 3rd.
