The variety of monster designs was fun to read through. The artwork also fit very well and was fun to look at. Even if you don't plan on running this system, I still think this book is worth it for the various monsters within.
I found this book very useful in trying to create my own campaigns and scenarios. The added aura and possible blessing listed in part two of the book were extremely helpful. I had no issue with this being a pdf the bookmarks are very well laid out and I had no trouble quickly navigating to something when I needed it.
