Here is an idea. I think it would be good if the job you choose to do could influence your powers in certain magics.
For example if you were an artist or a tamer, you would be good at summoning animals, because an artist has good imagination and a tamer, well he works with animals. (brown way, i think it was)
And a musician could have better powers in illusions (Azure way)
well, that\'s the idea. What do you think?
