This book is great. It is an essential book for anyone who plays DCC Rpg.
Essential! Let's face it, one of your players ( or you) will want to play a Wizard, and a Wizard will want a Patron. The reality is the core book only has a few.
Another reality is that creating your own Patrons is a lot of work. A lot.
This book has 24 new fully developed Patrons. 24!
It even has a new idea : Demi-Patrons. Less powerful Patrons, but they may be less demanding. Their goals might be more in line with the character, and their power can grow along with the characters.
180+ pages of sheer awesome.
This is the best source book I've seen for DCC rpg in a long long time.
Go buy it. Now!
