For the love of all that is holy

.....I don't think that's how it'd go
He'd probably have better understanding of maybe his martial arts or something
But he wouldn't get smarter, even in games warriors don't bother much with their int stat but wizards/mages do

I guess I'm frustrated that there are two whole stats (charm and int) that are being completely ignored and so we don't know what increasing them specifically will do. What if increasing int opens more system options? We don't know. What if increasing charm increases fame gain? We don't know. Maybe it's talked about in the light novel but right now, idk
