There is no point system at the moment for battles, but if I or the other Admin see constant "I use a replae justu to escape, or I dodge". Then i will add the point system.
This is how the battles work:
At the start of your fight post your CURRENT charka points at the end of your post. As the battle wages on and you use justus or take damage deduct the points from your charka. The battle is over when somebody reaches 0 charka points.
I'm sure I don't have to explain how to fight, but If i do post in the FAQ section and I will it explain it there.
