As a GM you can NEVER have too many puzzles! This supplement comes with all 100% top tier puzzles and is worth every single penny! Your players will love getting to a puzzle with a handout (I know mine do!) and these have a wide variety of puzzle types.
I ran the iron golem puzzle (the last one in the pack) for my podcast and it was so much fun watching my players scratch their heads to solve it!
