Acid Spill

You splatter slick pools of corrosive acid at up to three spaces within range. Each pool occupies a 10-foot square, which becomes difficult terrain for the spell's duration. Any creature standing within one of the pools' areas when they appear, must make a Dexterity saving throw. On a failed save, a creature takes 5d4 acid damage and is knocked prone.

Any creature that enters one of the pools, or who ends its turn within one, must also make a Dexterity saving throw. On a failed save, a creature takes 5d4 acid damage and is knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can create one additional pool of acid for each slot level above 4th.
