The jutsu allows the user to flow their chakra through any given item such as kunais, sword and the body it's self. When it is used through the body it can create a field of green electricity and attack the surround if used on a opponent's body the user can numb the users body and/or electrocute them. If used on a sword the sword's cutting ability will greatly increase, if used to cut a opponents the user can electrocute or numb them. Kaminari used this ability on his brain to prevent from a opponent to use genjutsu are read his mind, he again used it on a prison guard to electrocute their brain to instantly kill.
