Toribash
Qi can be bought from the Torishop or won manually through games. Belts are determined by Qi; 0 = white, 20 = yellow, and so on with green and blue, then 1000 = black, 2000 = 2nd dan, and so on. Some items have Qi restrictions and you will not be able to buy them or gain them in a trade until you have the required Qi level.

Also; be a little more careful about where you post threads. This isn't really a big deal, but a simple question like this should be in Rapid Threads or Beginner Sanctuary. Support is for actual problems involving Toribash, not just questions ;) Hope this whole post has cleared some things up. Enjoy your stay at Toribash!
