How do you raise INT and CHArisma?
Viewing post in The Lipomancer's Realm comments
For INT, the current method is by reading books. As for CHA, currently only situations that give CHA-based bonuses (ie the tip event at the Widdling Woodsman) give a small amount of CHA exp. Just as there aren't many places where CHA comes into use, there aren't many ways to raise CHA exp at the moment.
