From what I understand, they have absolutely no clue how things work in this game and also aren't trying to learn. So I'm fairly sure they'll deny/refuse it even if he told them. I would've stomped them with words in /party if I were you.
I can't seem to get a 16cha/15wis roll no matter what. Are you sure about the rolls? Thanks for the guide, much appreciated. It helped me a great deal.
