  1. Joe

    I love this book! It has that old 1st edition feel with 5th edition rules. The art is fantastic and the content is better. There is something for everyone in here for sure. My personal favorites are the rules for survival (hunting/foraging), the rules for momentum which is a fun way to get fast past exciting encounters, and the rules on darkness and light which is something I find I want in all my games but seems especially useful in an underworld setting. Though this book is focused on exploring the underworld, I can see using many parts of it in all of my games. Also TABLES! SO MANY TABLES! I do love a good table.
