I just got my comp copy of
Azagar's Book of Rituals. I've only skimmed it so far, but it is looking pretty cool so far.
So...yeah...if you haven't bought a copy, maybe you should think about it. It's got a whole three rituals written by me: Beast Cloak (page 21), Hallucinatory Regiment (page 45), and Circle of Ruin (page 71).
