As with the vast majority, but not all, books that bite off huge taxonomic groups this one fails to provide detailed updated information on this group but does provide an overview and excellent illustrations. If you desire more than the basics purchase Johnsgard's books or some other title that limits its treatment. If its the basics that you desire its worth the money.

This book was poorly made, not worth your money. i don't know [who] wrote this but he really needs to go back to english classes. The book was not put in order. They just took the diablo II computer game and put it in a book without worrying about the rules of 3rd D&D.

Do yourself a favor...Don't buy this book!

As an avid Diablo 2 fan I have anxiously awaited this new release in the Diablo storyline modules. The description of the product as covering the entire Diablo 2 game from Act One to Act Four merely wetted my appetite for more. Imagine my dissappointment to find a product containing poor guidelines for encounter levels, recycled artwork, pages of filler (repeated monster descriptions from Diablo 2: Diablerie,) and typos so obvious you would think that this was rushed into production and not seen by a proofreader. Any adventure whose pricetag is 50% higher than the price of the core books should be stunning in content and form, presented without errors, and be clear in the descriptions of game mechanics. I have only the highest praise for all the changes made to the new edition of the rules. The sliding exp scale, rewritten character classes, and the smoother combat all add to the enjoyment I and my players experience in our weekly sessions. The first Diablo adventure had us playing 8 hour marathon sessions each night for almost 2 weeks. Perhaps my expectations were too high for this product, but it is disappointing in falling short of the standards I have seen in other books recently. I am sure that any inconsistancies in the rules contained in the product will be brought up in a forum either on the web site or in Dragon Magazine, however nothing can take away from the flow of a session as greatly as a player stating "... but I read online that ..."
