As a PDF: The clean and simple layout works well for PDF format, and the influence of Malhavoc Press is clear. Full-page colour pictures are all very well in a glossy hardback book, but a complete pain when chugging past in your Acrobat Reader - Blue Devil Games are wise in avoiding such unnecessary fluff.

As a Supplement: This book follows the usual 'spaltbook' format of providing new spells, new feats, new prestige classes and new monsters. For me, it is one of the better examples of such work as it passes the acid test - do I feel inspired to use the material? The answer is yes. Most ideas are simple yet elegant (such as the venomous template), and many spawn adventure ideas (a personal favourite are the Bleak Gnomes). The addition of Arcana Unearthed conversion notes are particularly useful to this AU player.

And all at a very cheap price, too.
