Acid Spit

You inhale and spit a stream of acid in a 15-ft-cone in any direction from yourself. All creatures within that 15-ft-cone must succeed on a Dexterity saving throw (save DC 10+STR modifier) or take 6d6 acid damage. The acid dripping and foaming in your mouth deals 1d6 damage to yourself.

This spell’s total damage (to yourself included) increases by 1d6 when you reach 9th level (2d6), 13th level (3d6), and 17th level (4d6).
