Ain't gonna lie, after that post a few pages about how we're overloaded with magic as is and then going ahead to make another mage, this seems a bit, ah, [i]odd[/i], to say the least. Besides, there isn't a class in any game that can utilize both offensive magic and healing at a base level, let alone a class we'd be using here.

He can't utilize both healing and offensive magic. At the beginning of his life he could utilize dark magic. As he learned healing magic he lost the ability to use dark. This is effectively a realistic version of a Fire Emblem Class Change. If you're referring to the light magic tome he can't actually use it. He can make his hand glow slightly and that's going to be it till he gets upgraded to a sage. He wants to learn light magic but he can't actually use it offensively yet.

He's got a background heavily based in magic but he's not a mage anymore.
