I been playing a Human Int Rouge in PFS and I trying to get all the Knowledges as class skills. Then I noticed that Humans have the Racial Trait called 'Comprehensive Education' to get all knowledges as class skills. Sadly I played too past the level 1 edit to do it that way. I been looking around thought the books and forums to see if I can pay to retrain 'Skilled' into it but I getting no defined answer. My question is is PFS Legal? And if no, ways to get the knowlegdes as class skills.
