One of my characters has charisma 8 and zero in persuasion, and somehow I manage to have four followers plus the dog. She is so evil that even Virgil has right now -100 alignment.
In the order: Virgil Torial Kel Z'an Al'urin Tollo Underhill (BTW his reaction is 95) Of course I cannot leave them anywhere because they won't rejoin with me.
