I know this might not be the appropriate place to comment on this, but "training" charisma doesn't seem to make much sense in my opinion. If there was a "Persuade" skill instead of charisma to be trained, then it would make more sense. I don't think charisma is something that really can be taught, it is more of a capability that develops fully with practice in regular social interactions, and neither I think there are plastic surgeries in Yliakum to make people improve their appearance. Charisma, like Intelligence, should be untrainable, and if improvable by other means rather than paying a training to make magic with the OOC progression points to make your character prettier and speak like a great leader all of a sudden; the amount you could improve them realistically should be very limited.
