It's a very helpful book. well set of books. there are three books in the box. the first explains the basic elements of making a great adventure and explains the adventure forms that are found in book 2. that being said book two is composed of forms to help organize your adventure session so your not scrambling around for stuff. it has two blanks of each form and permission is given to photo copy the blanks. Book 2 also has one of each form filled out as an example for you. Finally book 3 is the adventure cookbook. It contains tons of stuff for on the fly adventures and tables so you can roll a random adventure. Great for those times or thing where you just can't stop drawing blanks. Overall I highly recommend this AD&D core accessory. ( )
