Well, I think wisdom might be a bit off due to like you said however spirit might be a bit off too. Other than the fact he essentially did a mental attack which in most novels calls them spiritual attacks. Why not call it Mind as a stat instead this way it can be spent differently on multiple different states of use that take the mind to do. Examples can be learning magic easier or other language's. Learning arrays and maybe being faster in learning other skills or figuring out stuff a bit faster or getting epiphanies more often when thinking about or making stuff for his ideas. The possibilities are endless.
Pwnzer:This makes a lot of sense. I tried looking at a thesaurus but yeah, there is no better alternative to wisdom there. Mind might be the way to go. I think I'll be changing it thank you.
