A great collection of extensions for OSE with modifications of the arcane and divine magic systems, as well as options for missing players, and dragon customizations. Awesome supplement!

The content is good, well-formatted and interesting - I think it will make for a fun series of adventures. I'd give it a higher rating if not for the quality of the print version.

The POD hardback was horrible - the gutter was too narrow so that the pages all ran into the binding making them hard to read, and the paper feels cheap and was very wrinkly. Get the PDFs and forget about the print verison.

This book provides a ton of great variants to the monsters in the Monster Manual and the differences are interesting and meaningful, not just minor tweaks. Well worth the price.

Great old-school style fantasy line art you can use in your own projects. A good selection of weapons and miscellaneous items that make good filler or sidebar art.
