Acid Burn

You hold a vial of acid above your head and magically shatter it, raining a spray of acidic formula in a 15-foot cone in front of you. All creatures in the cone must succeed on a dexterity saving throw or take 1d4 acid damage. This spell’s damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
