As an action, you can spray acid from glands in your mouth, targeting one creature or object you can see within 30 feet of you. The target takes 2d10 acid damage unless it succeeds on a Dexterity saving throw against a DC equal to 8 + your Constitution modifier + your proficiency bonus. This damage increases by 1d10 when you reach 11th level (3d10) and 17th level (4d10). You can use this trait a number of times equal to your Constitution modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.
