I am long time fan of the Sabbat. I really like that it's a complement to the official V5 Sabbat book, not a replacement. The book focuses on the important stuff, a fully fleshed out character creation process, a bunch of Sabbat specific predator types, a good look at the main Paths of Enlightenment and some new discipline powers and a bunch of new loresheets, including 2 Revenant family ones. It also looks at different types of sabbat packs, ritae and some pointers on how to run Sabbat games.
