Then it's bought and downloaded.
I did however buy the wrong product first and got the main Echoes of Heaven book, and when I finally managed to buy the bestiary I first bought the d20 variant before finally getting the book I set out to buy.
After looking at it I must say that the stat blocks in the HARP variant were much easier to read than the d20 variant. I don't know if it's because I play prefer HARP or because of the amount of information needed for the d20 stats don't lend themselves to good layout like the HARP stats do.
Anyway I got the setting book as well due to just looking up a page in the history of my browser and clicking add to cart. I'll have a look at the setting later, but for now it's the monsters I wanted.
I've had a quick look at it and it seems to be a very good book. Good layout, lots of information and lots of fiendish creatures for me to pit against my poor unfortunate players. The elemental wraith looks like an instant favorite, can't wait to try a couple of them out in combat against my players.
