My general take on magic is, for lack of a better word, Brent Weeks-ian. It's not as much about having access to a thesaurus of versatile multipurpose spells as it is being able to do one or two very specific, and clearly defined, things (that are not necessarily weak).

So if it's not necessarily raw power, but flexibility, that needs to be limited, that's perfect for me. As for what I specifically have in mind, that depends on how many people we get and what general direction they'd go in. Buuut I'm 90% leaning on something with mostly combat utility.
