So I don't usually purchase pdf-only products but after reading the reviews on this one I took my chances and bought it. And you know what, my choice was not made in vain, for this is one awesome product. It is taking me a bit of time and multiple re-readings to fully get the gist of everything, but now that I have, well its pretty awesome. The spell system is one of the more marvelous ones I have seen in D&D and its definitely a great product. I recommend it to all, I say buy it, read it, and use it.
My only regret is that it and its sequel are not in physical format because I for one would jump instantly at the chance of having this product in front of me in book format.
