Conduction

Lightning springs from your hand to deliver a shock to a creature you try to touch. Make a melee spell attack against the target. You have advantage on the attack roll if the target is wet or wearing armor made of metal. On a hit, the target takes 1d6 lightning damage and an electric jolt disperse across creatures adjacent to the target and one another. You deal an additional 7d6 lightning damage divided as you choose among any number of creatures along the jolt’s path including the initial target. You can do a minimum of 1d6 but a maximum of 4d6 to each creature along the jolt’s path.
