You can find a lot better guides on the Internet. They are very accurate and better than the Official Strategy Guide. The Official Strategy Guide also has many errors when listing what the suffixes/prefixes/uniques do. It's Shrine List also has many errors, and does not even include some of the shrines. It does not have any real good quantitative data, which are all available on downloadable guides.However, this guide has pictures and screen shots, and is also written in a story-telling like format which makes it interesting to read. But if you want the real numbers that the game uses, get a guide from the Internet. In my opinion, the guides on the net are a lot more informative and useful. Then again, they are not as fun to read as the Official Strategy Guide.
