Tonight the Pathfinder session ran roughly five hours. Which was good, it never dragged or became boring. The party had a couple of near death experiences. I really didn't want to fudge the rolls or "let" them live, but really, a chance encounter with 3 trolls would have ended them. They met the green buggers in a field, based on movement alone, the trolls would have overtaken them. Even if they had split up, they were a party of three. All three would have been digested and pooped out.
