Ok, I did some major training at the Mithril Caves, as I just got there from the Midgar arc and all my characters including Yuffie are level 33+. You think it's possible at the rate I'm going to be level 50 by the time of Nibelheim. Someone on here once posted they attempted to get their characters at 50 by the time of Nibelheim because that's what level Sephiroth was in the flashback. I inherited this goal basically, and am striving to do it.
