Cloud of Acid

You fill the air with an acidic cloud in a 5-foot-radius, centered on a point you choose within range. A creature takes 5d4 acid damage when it enters the spell’s area for the first time on a turn or starts its turn there.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 2d4 for each slot level above 2nd.
