Since you can't get your skills above 100, you will have to start working on some other skill if you want to level up. What I did when I wanted to level up characters quickly was I went through my skill trees and found a skill that I hadn't used at all....and then used it. You'll get points faster because it's not a honed skill so you learn them quicker. Keep in mind I play on the 360. And keep in mind this was done on a character that wasn't a specific build, and I had already found the Ogahma Infinium with this character and read it loooong ago before I even knew about the glitch so I had to do it the legal way, lol.
