I have to say I was expecting just a little dabble of haunts and maybe a few ghosts. I am very happily surprised by what I found in here.
The four haunts in here are very colorful but also very specific. That might decrease the value for some. However! What I did in enjoy was the use of the haunts as a way to further enhance an Occult style adventure.
This is especially true of the new Spiritualist Archetype list here: The Primal Spirit.
Here is a truly great take for those looking to accentuate their inner spirit channeler with some very nice natural features. Drawing from the Hunter Hybrid class, I think, is a very a smart move. My only real wish was that the alteration of the phantom was included, but otherwise I think this is an excellent archetype.
The other stuff includes a very interesting NPC type of Anti-paladin. I'm not sure about how useful it would be to a normal PC, but as a way to make a truly memorable villian , this succeeds greatly.
I love the artwork too. Some of it is very evocative and haunting. Great use of color saturation in the text background really drives home the creepy factor.
Overall I highly recommend this PDF for those looking for more Occult or even just some dark fantasy/horror stuff. HUGE thumbs up Flaming Crab guys.
