Not a fan of how this book tries to override lots of already existing material that worked perfectly as they were. Not a fan at all that Akhu, Wanga and Sadhana suddenly went Setite-exclusive, because that's not how those traditions were written in Blood Sacrifice. It feels like this book tries to generalise a lot of the old stuff. Greatest example is that suddenly all blood magic is willpower rolls only, just like Thaumaturgy for no apparent reason. This takes away from the uniqueness of the other traditions, and adds only uniformity and shallowness in mechanics.
Now this book isn't all bad. Lots of useful, inspiring and interesting stuff in there, especially about the sects and regarding infernalism. But to me this has without doubt been the weakest V20 supplement so far. Blood Magic and Blood Sacrifice are still more important and interesting supplements on blood magic for any Vampire-game. If you ask me.
