Corrosive Spray

A spray of corrosive acid coats an area 30 feet long and 5 feet wide, emanating from you in a direction you choose. Each creature in the line must make a Dexterity saving throw. A creature takes 3d4 acid damage on a failed save. If they are wearing nonmagical armour their AC is reduced by 2 until they spend a long rest repairing it. On a successful save they take half as much damage and do not have their AC reduced.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d4 and the range increases by 5ft for each spell slot level above 2nd.
