Reading the reviews, I’ve been dreading running this one. I finally ran it Monday and it mostly lived down to the reviews.
The first problem is clearly the mansion map, which others have covered in their comments. I needed to block off doors and areas to keep players from potentially going right to the boss fight, which I don’t believe is intended as an option.
Second problem is that we have another adventure that is just not going to fit into a 4-5 hour time slot for most people. There’s potential here for 4 mid- to high-level combats plus puzzles and plot. We ran 5.5 hours before we had to call it.
Third, it just didn’t seem scaled right. The boss fight (low-tier, 17 CP) was lethal. If this was a video game and the players had multiple takes at it, they might have had great satisfaction in winning, but with one pass, it was ugly.
Fourth, this is the continuation of a plot that’s been running for over a year through multiple scenarios. A high-level recap would have been beneficial.
On the good side, I’m finding the plot interesting and appreciate the development of an ongoing significant villain. There were some interesting ideas and moments of flavor in here too.
Clearly, from reviews, this is a deeply flawed scenario but still a key one for an ongoing plot. I wish Paizo officially recognized and addressed the problems through errata or forum comments rather than letting this thing fester out there.
