Honestly these Adaptable NPCs tomes (because let's be honest, they are), are something I wish I could get in a hardcover format. The stat blocks, the art, the adventures sigh it's all so good! As a DM who always thinks he has more time to prepare for a game then he actually does (i.e. prepping 20 minutes before the session) products like this are a lifesaver. The price may seem high, but the content and quality are well worth it.
