Acid Rain

An acidic cloud appears in the shape of a cylinder that is 30 feet tall with a 40-foot radius, centered on a point you can see within range directly above you. The spell fails if you can’t see a point in the air where the cloud could appear (for example, if you are in a room that can’t accommodate the cloud).

When you cast the spell, tiny droplets of acid begin to fall to the ground under the cloud. For the duration, any creature within the area of effect must make a Dexterity saving throw. On a failed save, a creature suffers 4d8 acid damage or half as much on a success.

At Higher Levels. When you cast this spell using a spell slot of 6th or higher level, the damage increases by 2d8 for each slot level above 5th.
