Thanks, but OK what I was wondering is this. Let's say that I plan to give Barter or Charisma to one character and try to only use that one to talk to people (hypothetical situation). So, I thought, selecting that character's personality AI at the start to something like Rascal (because Egotisticlal will give +1 to Bartering) would help. However, does that mean that:
1) I can't make my own choices, even if I'm talking to NPCs? And if I can though, then :
2) Does it mean that if I make choices that are, for example, Altruistic type rather than Egotistical, that the bonus can't go away no matter what?
