Contentwise this book is exactly what people where waiting for. It contains extensive and detailed rules for the creation of artifacts that are not magitek (which are covered in Secrets of the Lost Age) for all those players who always wanted to create their own artifact 5 moonsilver daiclave as well as long lists of all kinds of artifacts from common magic gadgets to powerful unique weapons. In addition to that, it also contains rules for erecting manses (and all other aspects of manses and demesnes) and a comprehensive collection of hearthstones of all types (Elemental, Solar, Lunar, Sidereal and Abyssal) that greatly enhances the choices given in the mainrules. Last but not least, it contains the full rules for thaumaturgie, the unexalted type of magic that is used mainly by mortal sorcerers in all its aspects from alchemy to geomancy. It really is a necessity for all groups with at least one character who wants to dip into the vast possibilities of crafting and thaumaturgy and still a useful addition for those just looking for more artifacts and new types of hearthstones. My only true criticism is about the quality of the PDF file itself. Due to no apparent reason, some areas in the book are lacking contrast, usually exactly box-shaped areas, which makes the text hard to read and the greatly reduces the quality of the pictures. In addition to the very small font size used for many artifact descriptions that becomes really an issue. This is even more annyoing since the printed book doesnt show this effect at all, which to me means that someone was sloppy when this PDF was created from the original printfiles. If not for this, the product would get the highest rating. I just think it must be possible to create a PDF without these flaws.
