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.
