You utter a vile phrase of primal spite, and massive, shimmering vines fling acid and spiral about a point you can see within range. Each creature within a 30-foot-radius, 10-foot-high cylinder centered on that point must make a Dexterity saving throw. On a failed save, a creature takes 10d6 acid damage and a -2 penalty to AC until the end of their next turn. On a successful save, a creature takes half of the damage and suffers no penalty to their AC.

At Higher Levels. When you cast this spell using a spell slot of 8th level or higher, the acid damage increases by 2d6 for each slot level above 7th.
