Acid Pool

A dull streak flashes from your pointing finger to a point you choose within range and then expands into a pool of acid. Each creature in a 20-foot-radius sphere centered on that 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 acid spreads around corners. It deals damage equal to 2d6 if a creature is in the pool at the start of their turn every round. Half as much on a save.

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.
