I know, and I approved it. Apologies, but I think I'm going to strike that from the class abilities while taking a good hard look over the rest of the classes.

Edit: Due to the reasons that I provided Freeshooter, I've struck Dark Magic from the Dark Knight and Grandmaster Classes, leaving it exclusive to purely casters because of it's variety of uses. This leaves us with:

Grandmaster(Sword, Anima, Light)
Dark Knight(Anima, Sword)
