Going into this book I was wondering if it had what I, as a 30 vet of D&D, would want in a monster creation type tome.
Well, I was happliy suprised by how indepth it really goes. Mind you if your not into learning game mechanics your going to find it a very long and pretty dull read but they also warn you as the reader of this fact and they are right.
The mechanics discused in this book are very indepth and comprehensive. It deals with ground up creation of monsters in all settings and lists LOTS of verried options for any level of diffeculty and experience.
They also put a random monster generator appendix in the back of the book consisting of many charts.
I think the only thing I may say is a draw back of this system is the math you have to do to calculate DC for the creatures you create. It's something Enistine might enjoy looking at.
Over all a great book and one of the most worthwhile RPG suppliments I have bought in a long time!
Great work Expeditious Retreat Press!
