Hey hey hey, I'm interested as well!

I kind of want to play around the idea of buffing magic that revolves around chess pieces. Sort of like chess magic wherein when you are bestowed a piece, you gain buffs corresponding to that piece. So it's more a mainly support type of magic. And they can summon a board where they can track all the pieces and then build the environment of the entire board from there, as well as possible enemy spots. 

As for their offensive magic, I was thinking along the lines of gravity magic and probably a war hammer of sorts. 

I'm thinking they're around B or A rank, depending on which you would prefer to have. But I think they're gonna be an experienced mage.
