A wonderful book. Not a wonderful base adventure - but a wonderful book. Full of great ideas regarding worldbuilding and relationships with people and factions. This is not a "heist" the way you'd imagine it. It's a very very slow roll. Don't expect much planning and storming through a vault - this is more of a urban investigation story.

If you're a dm that doesn't mind spending a LOT of time at early levels, meeting npc's, working on your own place etc. and doing a lot of prep between each session - then you'll get a lot out of this book

If you're a dm who wants to just have an adventure to read a day before the session and roll with whatever the book offers as necessities - you'll have a good time! You won't be making the most out of the book but this adventure is decent raw. (just rebalance the first encounter with a funny 4 legged being. You'll know what i mean when you read that thing's abilities. You wouldn't want an irreversible TPK., no?)

However, if you're looking for an adventure that doesn't invoke choice paralysis in your players, doesn't force you to homebrew things to make them great, and most importantly - goes above and beyond with it's setting, like Curse of Strahd then go get that book instead, really.

Not actually a heist und you have to homebrew a lot to make this work. Nothing for new Dms but it is a good base if you want to set an adventure in Waterdeep.
