The pdf closes with 2 new spells, Bestow Affliction(Clr 4) and Teleport Attack (??? 7), the latter of which unfortunately does not say whether it is arcane or divine, though I suspect arcane.

Conclusion:
I am dead tired of the commodity-magic-items and weapons that seem to have taken hold of so many games and this is a step in the right direction - these are qualities your PCs won't necessarily expect in a weapon and there, at least in my opinion, should be more books like this out there. The abilities never felt overpowered or useless to me. The artworks of the weapons (this is a full-color pdf, btw.!) are beautiful and while I usually don't like obviously computer-generated art, for this file, they work excellent. However, there are also some downsides to report, namely some editorial glitches, a typo in the "fortunate" weapon description as well as the missing class-descriptor in one of the spells. Additionally, while not required, I would have loved to see some IC-introduction or some more far-out abilities. While some qualities really rocked and I loved seeing an updated version of material from "When the Sky falls", I nevertheless felt that this book could have been even better. My final verdict, for what the book is and due to the fact that it comes with a 22 pages B/w printer-friendly version, will be a solid 4 stars, a good buy if you want to add some options to your magic weapons.
