Query: A book containing useful and unique information.

This book is organized pretty well, and contains a lot of useful information; especially about weapons and armor that you can hardly see in any other book. Plus, with option of weapon mastery and added combat tactics, your boring fighter may become as exciting as a spellcaster... There is much more in this book, buy and see! Definitely worth the price.
