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.
