Acid Geyser

A vertical column of pungent acid roars up from the ground in a location you specify. Each creature in a 10-foot-radius, 30-foot-high cylinder centered on a point within range must make a Constitution saving throw. A creature takes 4d6 acid damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the acid damage (your choice) increases by 1d6 for each slot level above 2nd.
