I played the high tier version of this scenario as the Kyra pregen. It was one of the first PFS games I ever played. I had a lot of fun, particularly with investigating grisly murders in the dark heart of gothic Ustalav. There was a time limit, significant player challenges both with combat and roleplay, and an interesting chase scene toward the end. Mauler leaves room for player creativity and there is more than one solution to the main problem. I highly recommend this scenario!

Besides the horrible attempt at a chase mechanic everything was good, Story was interesting enough to keep everyone going.

perspective: GMed Low Tier, characters in play Ranger/Druid 3, Paladin (Sheylin)4, Paladin (Iomede)5, Witch 3

I can't wait to GM this one more! Its an investigative romp trough Ustalavs ex-capital and more than that, a race to get the killer.
What I loved the most was that investigative/diplomatic PCs really shone troughout this one.
I love the drama and interactions it provides and its basically just up to the PCs to make the most of it.

The chase was very cinematic and even slapstick fun with two paladins barely managing to get trough (we had some really bad rolls on the table) .
So when the ranger caught up with the Mauler, he was alone and the Mauler critted *twice* so there was a touch and go moment for the party till the rest caught up.

Other encounters also could have been more challenging but I can see them easily making problem for different groups.

All in all, the players gave very positive feedback and with a roleplay oriented table, I had great fun as well.

I almost gave this scenario 1 star but I felt it wouldn't be fair to penalize the whole module for the "chase map". However, after experiencing one "chase map", I would have appreciated it someone told me upfront before I played a scenario if there was a "chase map" so that I could avoid it. As such, consider yourself warned about the "chase map" - if you dislike it strongly as I do, this is probably a module to avoid.

In any case, I did not read this scenario and only played it so can only comment based upon it accordingly. Needless to say, since there is a "chase map" in it, I don't intend to ever read or DM it. However, I felt the story was very well designed and the NPCs possessed detailed backgrounds and were sympathetic. I really enjoyed the werewolf story and character motivations. Also, some of the faction missions did have interesting twists.

I've run this scenario 22 times now and I am still not tired of it. It has a simple plot and moves very fast without seeming like a railroad. The combat elements are a let-down but the strength of the scenario's role-play elements make up for the short fights. I enjoy running this scenario because the objectives allow for the players to be creative with their problem-solving. The scenario allows the GM a lot of flexibility to improvise and have a lot of fun. The faction missions are good for the most part, a step up from what has become the status quo. The campaign setting flavor takes some work on the GM's part in order to bring to the surface. I highly recommend that any GM prepping to run this get a copy of Rule of Fear and especially make an effort to read the section on Ardis. Overall it's a very entertaining scenario and worth the effort to prep and run as much as possible.
