Raiton is one of the basic 5 elemental nature transformations.It allows user to generate lighting by increasing the high frequency vibrations of their chakra, allowing for piercing damage and fast movement. Electricity can paralyse target so it is good to use before last hitting. Also Lighting can be infused in weapons through chakra flow.
Lightning Release is common to the ninja of Kumogakure.
Advantages:
It can numb opponent so we can easily last hit U_U
It can be infused in weapons.
It has ability to paralyse opponent.
Disadvantages:
When used on bigger range,and is released from body it is not as fast as real lighting which means that opponent has time to react.
Lighting is strong against earth because it can travel trough it and also reak it. But lighting is bad against wind because wind is natural insulator of lighting.Also lighting is strong against crystal,ice,scorch,shadows,bugs,blast,sand(seen in Gara vs Sasuke fight),Shikotsumyaku,Lava,wood.
And weak to storm,dark release,papers.
Also water can incrase the power of lighting.
It is also much more powerful when natural lighting is used(Sasuke vs Itachi fight) when Sasuke first used fire tecnique to make thunderclouds so he can use natural lighting.
Kekkei genkai is Storm release which is mix of Lighting and water.
