Into the Armory: The Complete Guide to Weapons, Armor, and Equipment
This Sourcebook for the 3.5 OGL and the Pathfinder® Roleplaying Game contains cartloads of new weapons, armor, and other equipment for DMs and PCs. In addition to these tools and treasures any adventurer would kill to have, this book also contains rules for Quasi-Magical items, a new class of semi-magical utility designed to both provide useful tricks for clever players, and to provide fun and exciting adventures. Finally, the book provides a set of optional variant rules for using siege weapons, and a number of exciting new siege weapon enhancements designed to enhance your game whether you use the variant rules or the original ones.
