A great, detailed enounter list for Curse of Strahd or other Ravenloft compaigns. There is also plenty of bonus short suppliments in the back- I won't use all of them, but they are neat little single-page ideas you can hand-pick and use to personalize your campaign.
The encounters themselves seem to be a good mix of the dangerous, comical, creepy, and thematic. The only thing I would have requested additonal is some sort of CR range or other rough "danger guide" for the combat encounters, just to make it easier to skip or drop in warning signs early for exceptionally dangerous encounters when rolling on the fly. Still, a great, professional supplement, and in my opinion good value for the money.
