Technically the lore suggests that some people's Echo grants them the ability to learn more quickly, and to learn multiple disciplines. One of these people is the Warrior of Light, who is able to master most - if not all - disciplines of War, Magic, the Hand, and the Land.
However:
I feel like most people agree that that's a lore fudge to excuse the game mechanics of people mastering every class on one character. If you're interested in gaining people's approval in RP, I would advise caution.
Most of the time, in most RP, people will be put-out if you say your character is a master in every field. Like, their character has spent her whole life studying to be X, and your character is just as good as her or better... and better at Y than her friend, who has also spent his whole life studying Y... and better at Z than his friend, who has spent their whole life studying Z? It feels unfair. Especially when you're talking about, like, twelve different disciplines.
It's best to pick one or two, three tops, that your character best at, and say they're dabbling in the rest. It can be fun to roleplay learning from others! I would leave your character room to learn from other people's. Having her begin as a master at everything to begin with does not do this.
And even in stories (rather than interactive RP), people relate more to characters that try and fail than to characters who succeed at everything. Decide what you want your character to do with their life; what do you want people to think of them as? Then pick their skills to bring that idea across.
