The book is broadly divided into several sections, covering weapons, armor, hearthstones & miscellaneous items, and warstriders.
I found the book to be an exciting and engaging read. It took me a few pages to warm up to the weapons, but by the time I got to the armor section I was sold. The Warstrider section blew me away.
What I liked most was that the book didn't just provide weapons for killing and armor to prevent being killed - it showed how artifacts could be turned to other purposes beyond their obvious functions, and it did so in interesting and mechanically satisfying ways. The Warstriders chapter sets the gold standard for the book.
An absolute must buy.
