The ground and any liquid within a 20-foot-radius sphere centered on a point you choose within range becomes an acidic swamp. Spaces on the ground or within liquid in the area count as difficult terrain for creatures other than you. Whenever a creature enters the area for the first time on a turn or starts its turn there, it must make a Constitution saving throw. The creature takes 2d6 acid damage on a failed save, or half as much on a successful one.

At higher levels: When you cast the spell using a spell slot of 4th level or higher, the radius of the sphere increases by 10 feet for each slot level above 3rd. Additionally, the damage of the spell increases by 1d6 for every two slot levels above 3rd.
