Lightning Breath

For 24 hours after drinking this shimmering gold liquid, your voice gains a crackling quality to it and your breath sparks and sputters. For the duration, you can use a bonus action to exhale an arc of lightning at a creature you can see within 30 feet of you. The target must make a DC 12 Dexterity saving throw, taking 1d10 lightning damage on a failed save, or half as much damage on a successful one. Once you exhale this lightning, the effects of this potion end.
