Loving this book! Coming up with unique encounters is always a top priority so having a book that is more than just monster or maps is huge. I love that it works some kind of special complication or unique element into the lairs to challenge players. There are also a lot of DMs Thoughts boxes throughout with specific advice for running that kind of lair or a specific mechanic from James, Mike and Scott that really help with that lair but are also great general advice. I ran the Dragon Mummy's Rage lair last week to the enjoyment of all and looking forward to trying more.
