Acidic Barrage

You unleash a rapid barrage of acidic projectiles in a 30-foot cone. Each creature in the area must make a Dexterity saving throw. On a failed save, a creature takes 7d6 acid damage and has its AC reduced by 2 until the start of your next turn. On a successful save, the creature takes half as much damage and does not suffer the AC reduction.

At Higher Levels: When you cast this spell using a spell slot of 6th level or higher, the acid damage increases by 1d6 for each slot level above 5th.
