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)

This is also more in line with how the games represent Elder Magic anyway. It's always treated as an exceptionally exclusive art that takes years of dedication just to get 'decent' at it. You can't just pick it up as a hobby later in life like you can Anima Magic. Even in Awakening, which was very lenient in its abilities, Elder Magic was still restricted to Dark Mages and Sorcerers only (Just ignore Aversa, she's a super special snowflake villain). Despite their names, Dark Fliers and Dark Knights (as well as the versatile Grandmasters) could only use Anima Magic, not Elder Magic.
