Potion of Fire Breath

After drinking this potion, you can use a
bonus action to exhale fire at a target within
30 feet of you. The target must make a
DC 13 Dexterity saving throw, taking
4d6 fire damage on a failed save, or half as
much damage on a successful one. The
effect ends after you exhale the fire three
times or when 1 hour has passed.
