To begin I concentrate my Raiton chakra and I then channel it into my right hand. There I start to gather my chakra, quickly building up a mass of chakra that should be more than enough for this technique. I then focus the chakra around my hand and jump into the air, crossing into short range of your clone while in the air. I then land on the ground and slam my hand, releasing the chakra and using nature manipulation to transform it into lightning. *By doing so I create powerful bolts of electricity that surge through the ground towards your clone, shocking him.*
Adv-no hand seals
Disadv-the electricity is short range only
The electricity present around your arm before you use the technique could give away your intentions
As for your counter I would rate it as good. This is mostly due to the much faster speed of use than my own technique, as you could easily observe the elctricity around my hand and as I jump into the air you release the bullet and knock me backwards. Thus easily countering my technique.
As for speed of use I rate this technique as slow. This is mainly due to two factors. The presence of the electricity around the arm before you use the technique. This gives the enemy some insight into your intentions.The second being that if you are mid range from the opponent you must jump through the air towards him otherwise the electricity won't reach him since it only affects short range.
Also I have a question

about the two main types of lightning(unfocused and piercing)and how they react to water:
If an opponent used an unfocused electricity attack towards you and you counter with a higher rank water bullet, does the water overpower the lightning and become electrified?
Also if your opponent used an attack like flase darkness sphere an you used a water bullet of the same rank, would the two techniques continue through each other with the water becoming electrified?
Sorry for all the questions >_<
