Acid Rain

A swirling, hazy, dark cloud appears above a point you choose within range and then sheds down a torrent of purple and green globs onto the area. Each creature in a 20-foot-radius, 20-foot-high cylinder centered on a 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 acids spreads around covering the target area. A creature that remains in the area or enters the area until the end of your next turn will take an additional 1d10 acid damage.

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.
