∆Ability levels:
-Beginner: Everyone who starts to learn something is at this point, you stay here as long as you are not skilled enough. Be careful when using your anything. There are people with a talent to blow things... it happens quite often while they learn magic.
Intermediate: You move here when you can use an ability smoothly. But you still have long way to go. Many get stuck here for a really long time. You are now able to match some people on your own.
Advanced: Congrats, you either worked hard enough to get here or just have a pretty good talent, but now that you are here you can say that your abilities alone match that of dozens of people.
Master: The dream of many but a hard to reach level. At this level you can match hundred of people by yourself. There are still people who reach her with talent alone.
Grandmaster: A lever higher. You thought you mastered everything you could? Too bad, there is always someone better than you. Honing your skill is a long path where you might not find an end, but those who still try to walk onto that path will arrive here sooner or later.
PENSAMENTOS DOS CRIADORES 
Nyarlathotep00
Nyarlathotep00 I mostly did this to have an idea about the levels inside the FF. Haven't really implemented it yet though...
The ability levels will not be seen in the story by the way... it is just to keep tract of how good the abilities of the MC are. I might change things in the future... so don't take them to seriously.
In the Canon there is not a proper level to gauge their abilities either so I am bound to make mistakes(more than I already make).
