You draw an arc of lightning between the material component and the tips of your fingers, then sweep it out towards a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d6 lightning damage. If you roll a 5 or higher on one or more of the damage dice, the lightning leaps to a second creature you can see within 20 feet of the original, and you can make a second ranged spell attack against the new target. If you roll a 6 on one or more of the damage dice for the second strike, the lightning leaps again towards a third creature you can see within 10 feet of the second, and you can make a third ranged spell attack against that target. The arc cannot target a creature more than once or target more than three creatures.
