This was an interesting adventure and I was able to drop it into the campaign I was currently running. However it did have some problems. When the players get to the core of the adventure and finally get to the chapel, the encounters are not balanced and the pigs are much harder to kill than the nightmare and the bad guy. He was easily dispatched with a couple of fireballs. The Fiendish Boars took nearly an hour to get through. It had the right idea, but our entire group has now been turned off pork for awhile due to the sheer number of pig puns that ensued from the encounter.
