There's a lot of good stuff in here. A LOT. But ...

There are some real problems with a few of these adventures. Typically with maps. Tried to run Vault of the Once Great Thief and there are severe problems. It's literally not runnable as is. The map image and the book map don't even match, and I'm not sure either one is correct. Once the second tumbler is in place there's no way to move forward. Or, if the solution is more complex than just setting 1, 2, 3, and 4 in order that really needs to be spelled out. It's not just me, there's an entire thread on the Arcane Library Discord about this map and how no one can figure it out. And for good measure people have some complaints about several other maps as well. 

Anyway ... there's a reason I'm not giving this one star. There's lots of great adventures in here. But if I'm going to run any of them I'm going to assume I need to make my own map, I guess.

I really hope there's a Shots in the Dark 2, and that the maps are a lot better.
