Okay, so I, uh...please do not think I'm trying to be an ass, but I frequent a writerchat with many English majors and a few professional authors and may have run this character past them...here are my criticisms and suggestions, as supplemented by them. 

Your character is sort of overpowered, in the sense that she has little limitation, few character flaws, none of which really balance her abilities, and that her abilities are obscenely multipurpose and effective. Having them only last for a few seconds is not a suitable limitation when they link seamlessly. She's crazily skilled at about everything and bores easily; that about sums up her character. Saying she's jack of all trades, master of none does not excuse this. If humblebrags are your character's only flaws, you should probably rethink the character. 

I'm not saying I hate her, but she seems rather one-dimensional, as does her fairy. You have a good writing style, but I'm just not really seeing much that's going to be fun to roleplay with? A combination of overly adaptive and effective powers and a bland personality is just...not fun. Also, her powers seem to be very reminiscent of Darwin from X-Men First Class, though that's not really an issue.
