[quote=@Prince of Seraphs]
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.
