Does TotSC add more to BG AFTER the confrontation with Sarevok or BEFORE this?

Before, but if you've already beaten him, don't worry! You can reload the final-save and then do all the quests and stuff, then fight Sarevok again! Joy :rolleyes:

It near doubles your XP cap too

I'm at the Friendly Arm Inn, early in the game. I just wanted to know what to expect. I'm using the BG guide at present. Just snagged a copy of the TotSC guide online, so will be anxious to get THAT. Was concerned that I might go past a point where I should've done something that wasn't in the BG guide, screwed up my game, and been unable to rectify it. I like the way they did the BG guide, by the way, and I've read that the one for TotSC is s'posed to be good, too. I need all the guidance I can get. Thanks for answering my question.
