A very helpful review for folks who need quick information on the factions and how to incorporate them into your game. I liked that it compiles info into a single resource (as others have mentioned). I also liked that the rules for gaining renown. I also really appreciated the brief summary of locations in Faerun associated with each faction.

Overall, I don't think you can go wrong with this. A useful resource at a good price.

There's almost nothing here that hasn't been printed somewhere else. AND THAT'S THE POINT! 5E spreads a lot of mechanics and lore through a lot of different books and sources, so having it all in one place is invaluable! If you have a player who is joining one of the factions, don't skip this book so you can see all the lore, benefits, perks, ranks, renown, quests, items, spells, and contacts in one place! Drawn from official sources like Wizards' hardcovers and Adventurer's League material, and also top notch "unofficial" sources like Minsc & Boo and Darkhold, this book is basically essential if you don't want to be flipping through half a dozen documents to figure out what your Zhentarim player should get when they hit 10 renown. The fact that this product updates regularly with new additions - you caught that I just mentioned Minsc & Boo right? - makes it all the more worth the purchase. A must have!

There was clearly effort put into this and I think if you are looking for a straightforward way to give player rewards for joining factions than this does a pretty good job.

Some of the rewards are a bit generic. But they aren't any different than what Adventurer's League gives. Overall I recommend the product.
