I was hoping this book would be a good source of traps and tricks I could strip from their setting and use as I wished. Unfortunately, the book isn't great for that.

Unless you want to use the entire society they've built into this book and use the arenas exactly as they've been written, I would not recommend this partilar volume. It's just not particularly adaptable, and I never use anything "as is".

But if you're looking specifically for a secret society who loves deadly games to plug into your campaign, by all means... Buy this one.
