Am I nearing the end? *spoilers*

I've never fussed with Blue Magic much in this game. I think it depends upon your playing style or if you feel the urge to "master" the game on whether or not you'll go through the effort of finding the blue magic.

In my very first playthrough I used Blue Mage, but then after that never bothered to use him again. I just didnt have the patience to learn spells. I prefer a Sorcerer actually
