Potion of Acid breath

After drinking this potion, you can use a bonus
action to exhale poisonous gas at a target within
15 feet of you. The target must make a DC 13
Dexterity saving throw, taking 5d6 poison
damage on a failed save, or half as much damage
on a successful one. The effect ends after you
exhale the poison three times or when 1 hour
has passed.
