Potion of Fire Breath

After drinking this potion, you can use a bonus
action to exhale fire at a target within 30ft 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.
