This adventure breaks the line of CotCT style in an excellent way.

The adventure is a huge creepy "dungeon" that if the DM finds a way to expose the backgrupnd to the PCs, he can keep the PCs a the tip of their toes on every turn. This adventure was plenty of hack and slash yet if the DM sets the mood right, the combat feeling gets entirely different. The dungeon has such a great background that if you develop it nicely you can forget that you have beed dwelling in the same site for the past several encounters. The partition of the castle in wings makes a great way to imprint different feelings on each area and braking the phase of the castle giving the players a break on the "same place" feeling.

If you don't play CotCT I greatly recommend this module since its totally isolated, you can place it almost anywhere in most homebrew campaigns. A bit of a backgruod twist can fit it nicely into any home campaign.

On of the greates adventurers in the CotCT path!

As far as dungeon crawls go it doesn't get much better than this. Scarwall ranks up with Ravenloft as a classic haunted castle adventure.
Lots of great encounters/scenes. The danse macabre is particularly memorable and the Hellraiser touches are quite delightful. The spirit anchors give some focus and purpose to the crawl rather then it be an aimless wandering down (well the monsters get tougher going down so we must be going the right way...)
The Zon-Kuthon article is a great addition and fleshes out the creepiness.

“Skeletons of Scarwall” is my favorite entry in the Curse of the Crimson Throne path so far (“Seven Days to the Grave” now officially being my second favorite). It’s a site-based adventure set entirely in the titular Castle Scarwall, an eerie, brooding place packed full of all sorts of goodies. Undead are the most plentiful bad guys here, but there’s a handful of other critters to keep things interesting.

Designed in the style of gothic horror, Skeletons of Scarwall takes its cues from classic films such as Dracula, and classic D&D adventures like Castle Ravenloft. Its winding halls, elegant yet creepy décor, undead guardians, and occasional “boss monsters” also reminded me very much of the classic Castlevania video game series. Speaking of bosses, there’s a nastily iconic surprise towards the end of the adventure that will be sure to strike fear into any veteran player. I won’t ruin it, but let’s just say that fans of the classic “Tomb of Horrors” will be pleasantly surprised.

My only problem with “Skeletons” was its map. A few of the rooms are incorrectly numbered (room 38 is labeled 28, room 26 is labeled as 24), while other rooms aren’t marked on the map at all (22 and 29). Furthermore, secret doors don’t show up on the map. That’s a little too secret for my taste. These are relatively small mistakes however, and considering the sheer size of the castle, not unexpected.

My favorite part of Pathfinder 11, however, is the article on Zon-Kuthon. The author pulls no punches here, giving us an unflinching look at the god of pain and his sick worshipers. As a big fan of Clive Barker, I can see his influences all over the Midnight Lord. Fans of Hellraiser will rejoice, especially when they see Zon-Kuthon’s illustration; the dude could practically *be* Pinhead. It’s a shame, then, that this article was smaller than that of the three prior gods. I would have loved to see a Kuthite prestige class...
