He'll flip ya...Flip ya for real...
Paizo invented a new encounter called Haunts. They were like something between super natural traps and ghostly enemies. You could use magic and some particular items to suspend the haunt for a short period of time. Then, you had to use a ouiji board to decipher what happened in the space and how to finally lay the haunt to rest.I ran this when it came out. I liked the adventure path and the supporting sourcebook. Ustalav was pretty much Pathfinders Barovia/Ravenloft. We only ran the first adventure as the players got stuck at some point, iirc there was some type of mystery element involved in the adventure. Its been 10 years so my recollection is vague. I do remember there were 'specters" or "apparitions" and the mechanics for beating them were pretty odd. That's where the players got frustrated. Overall I remember the adventure path being pretty well written otherwise.
Most players hated them because it was a simple HP bag they could just beat to death. They were tricky, and annoying, but also incredibly interesting narratively. A shame they didnt get much love after Carrion Crown. I had a fantasy that someday Paizo would release an AP about the PCs being Ghost busters going around putting haunts to rest. Never gonna happen
