There is also a nicer way to deal with Odren - you can seal Demogorgon in as he suggests, then when you go to speak to Odren, tell him the demon wanted you to trick him but you're not going to do that. Odren and the Helmites walk off to think about what they've done and you get +1 rep. (But you don' get to fight Demogorgon).
I don't know that makes any difference to Jon though!
Haven't done that yet, but that's next on the list I guess. I've got his RC up to 47 right now... apparently, the mod relies upon the presence of certain NPCs... I've done everything the same as before, but because I have Imoen in my party, I got a new dialog that increased his counter by 3 points due to a conversation about dreams and Candlekeep and such. I wonder if I should sub in Jaheira at some point...
