As i got blown back with my hair standing, i took out a black sun glasses and wear it like some big hollywood star and silently said '' cool & no ''. As sempai me question i begin to speak while walking toward you slowly.
We can see lightning when there's rain/storm or some disaster, lightning is very fast, lightning is destruction it all about power and speed.
ninja can use chakra to shape lighting into some weapon such as spear/sword or even infuse into kunai or other object to increase it piercing power through vibrations & with the added effect of inducing numbness. or as allow the user to generate lightning by increasing the high frequency vibrations of their chakra, allowing for piercing damage and fast movement. The electricity paralyses the target so that they are unable to move and leave them vulnerable.
I would say, lightning is best use when dealing with solid object for example, if my target were to use mud wall i can send a strong blast of lightning to blast a huge hole on it and might kill him off if he didn't know the lightning coming. Or when the target is wet or standing on a river/lake or some water source spot you can send lightning to shock him to death or even paralyzes him.
Lightning weakness = wind
Lightning strength = earth
Lighting best combination = water
