Acid Rain

A dark cloud with a 20 foot radius appears, centered on a point you can see within range. Acidic rain falls from the cloud.

Each creature under the cloud when it appears and on your subsequent turns must make a Constitution saving throw. A creature takes 2d6 acid damage on a failed save, or half as much damage on a successful one. A creature must also make this saving throw if it ends its turn under the cloud. On each of your turns until the spell ends, you can use your action to conjure acidic rain in this way again.

If you are within 60 feet of the cloud, you can move it up to 60 feet as a bonus action on each of your turns.

At Higher Levels. When you cast this spell using a spell slot of 4th or higher level, the damage increases by 1d6 for each slot level above 3rd.
