From the back of the book: The Dragon Armour Adventure Book introduces a different way of playing D100 Dungeon, and will give you choices much like a "choose your own adventure" game book. It uses all of the D100 Dungeon rules from the main rulebook with a few modifications. Also included in the Adventure Book are some additional rules for D100 Dungeon that can be implemented into any of your D100 Dungeon games, whether you are playing a Quest, Campaign or an Adventure. Can you beat the Adventure?
