lol what are you looking at the ground for? I know this is your first time training, ever, and for a reply, that wasn't half bad. ^.^
Yes, lightning is good for short-mid range attacks and to be combined with metal (like sasuke did with nagashi on his sword), is weak against wind, and strong against earth.
So now, please follow me. *we climb up to a mountain dojo where it is storming with lots of lightning striking around it* now then meditate here *points to the open room in the dojo* for a whole day, focus on lightning, ur lightning chakra, and the power of lightning.
here's how the meditation thing works:
u post something like *sits down and begins meditating*, *continues meditating* (u can put more detail if u want), etc., and u wait for me to post if any time has passed. the time here passes a lot faster than in rl lol. now get to it.
and oh yeah, don't double post/spam
