I haven't played in well over a year. I believe I was around level 130. I am considering getting back into it. Is there a somewhat recent guide for bishops? (Do bishops ever exist? haha) Does anyone even use bishops anymore?
Please check out my KH amv at http://www.youtube.com/watch?v=pVe8Ir5HCo4
As dumpling said, that's just what you do. For future reference, try http://ayumilove.net/ for guidance. There may be a couple builds that are out of date, but they're mostly unpopular classes, like Jett.
