Ranking up was easy. Writing stories for missions to earn kumi is very hard for some reason. yet I can come up with any story in the battle arena.I'm chuunin, which Sage is trying to 'donate' me 1500 Kumi?
It can be official (no stealing). I need Kumi.A normal fight?
iirc its like this
1tails - Teno (Who I think has left so /might/ be open?)
2tails - Mirai
3tails - open
4tails - (kashin had it but not sure if still active? so might be open)
5tails - open
6tails - open
7tails - Shady Doctor
8tails - open
9tails - LGeezy
again its been a hot min since the list was updated
also battles currently give 500 kumi for a loss and 1000 kumi for a win, +/- 250 for rank differences.
So if a sage fights a sage, the rewards stay the same.
if a jounin fights a sage, if the jounin wins, they get 1250. if the sage wins they get 1000. if the jounin loses they get 750.
But these rewards are only for 'official' battles and do not give rewards for unofficial battles
I gotta start paying attention to the rules more.
