Ran this as a one-shot yesterday, and it was a lot of fun. Our game plans changed so I basically pulled this out in the morning, read it, printed the maps, annotated the maps, and I was ready to go. Players had a good time, I had a good time. Best of all, I was pleasantly surprised at how different elements of the adventure turned out (and every DM likes to be surprised, right?).
(Some spoilers below):
-a simple but effective hook (investigate ghosts in graveyard for pay)
-a map that has a lot of possibilities. There are at least 4 or 5 ways from the graveyard into the dungeon. The dungeon in not totally linear.
-a nice mix of monsters, traps, and tricks, and definitely not all the encounters have to be fights.
-some fun magic items like a magic globe that animated all the corpses in a 300' range. Of course my players ended up using it (not knowing what it would do) and caused complete chaos, having to flee the adventure (only on the way out realizing that the "ghosts" were just dressed up robbers, and that their (the PCs) actions has actually made the original hook come true).
The less good:
-Map could be a lot more effective for quick play:
- indications on it where the various entrances to the dungeon are and what numbered room they lead to (I had to add that myself).
- indications what doors are locked
- indications of traps, tricks and monster (they could all fit on the map quite easily and make this adventure almost runnable just via map)
- the random encounters need a little bit more, just some indication to say what the monster is doing when you encounter it.
- some things that kind of made no logical sense
- a demon guarding the tomb of the saint, except no indication if said saint is actually buried down there and theres no treasure associated with him... so why the guardian?
- there's a necromancer buried basically in the same complex who has the only treasure... which doesn't jive with the demon and his mission. Probably would have made more sense if he were there to keep people from raising the necromancer or something.
Overall though, cheap, easy-to-run, and fun.
