As I've said below, Mavis was the hardest part to determine... she is so mysterious ^__^

But, I believe she would have to be quite powerful. DS or not, she is the first master of FT, and from experience with them they are very strong and have a wide variety of Magic abilities. They all seem capable of performing the big 3 fairy spells (Hades doing it with Grimoire Law) but they also have other things that are their core Magic. I don't think we have seen any of Mavis' true abilities yet, so I'd like to think that that little girl holds heaps of kick-ass Magic that'll blow us away ;D
