This book (supposedly) provides info on the new features of the expansion set. The only really useful parts of it are the tables in the last part, and this does not work to those who haven't downloaded the 1.08 or 1.09 patch. There are many things in the guide that have changed after the last patch, including new items, rune words and crafted items.
If you have web access, search there for the info you need. This guide is a complete waste of time and money.
