The second best module in the trilogy, and the climax of the series of modules. It can be somewhat difficult to run, as a whole heck of a lot is going on simultaneously in Bulobo, and players may have some trouble figuring out the puzzle. Mine haven't had trouble and got it right away, but as others have noticed at least one or two riddles are somewhat vague. I strongly suggest giving the party a chance to have a short rest once they're inside, as the entire module is basically two combats back to back and if they've had trouble in Bulobo going straight into the final battle is likely to not be fun to play.
