Electrified Blade

You must make a melee attack with a weapon against one creature within the spell's range as part of the action used to cast this spell, otherwise the spell fails. On a hit, the target takes the effects of a normal attack and lightning arcs from the target to the nearest creature within 15 feet of it. The second creature takes lightning damage equal to your spellcasting ability modifier. The damage of this spell increases as the character levels up.
