So this is quite a pricey product considering that if you disregard the colated stat blocks, which I don't really find necessary, it's only really 18 pages. To make matters worse, the thing that I really wanted it for, the colated list of sidequests, has a lot of incorrect info in it. It lists locations of NPCs incorrectly multiple times, often placing them in a 'B' area when they're usually nowhere near the B level, meaning I have to go searching myself. There are only two variants of 'wandering creature' presented, which really isn't much for all the levels of the Abomination Vaults, and it doesn't really play into the theme that much. To be honest, I was hoping to see different encounters for each level of the dungeon, but as it is they're all just variations of 'cultist', they're hardly worth using without putting in significant work of my own to flesh it out and add variety. Then there ar ethe new side quests presented here. The first one can hardly be called a side quest. It's two combat encounters strung together by some poorly concieved plot that sees an old man so hell bent on getting his bag back that he'll rush headlong into danget for it, then turn around and just give it to the party as a reward. It feels like just an excuse to give out a bag of holding. The second side quest is not so much a side quest as an alteration to a part of the adventure. It adds some enemies, but also weirdly removes one, at least temporarily. It makes it seem like the plots and schemes of these new foes could drastically alter the factions and politics of this level, but provides no meaningful way for that to happen, and indeed, seems to assume that it won't. It also presents a large amount of backstory to explain why these foes are here and what their plans are, but provides no emaningful way to impart that information to the players. All in all, not worth the money IMO.
