I bought this specifically to get my hands on the Blighted Fey and Mana Wastes Mutant templates, and I love them. I've been frustrated at the lack of "fey gone evil" options I had, and now I've got them!
I love that the monsters in this bestiary are versatile enough to use them with the Golarion flavour or as monsters in a homebrew setting. You can bet my players are going to be running into some monkey goblins or water wraiths soon ;)

Read my full review on my blog.

The Inner Sea Bestiary is really an excellent book, one that manages to add yet more monsters to the game but still fill a niche for the Golarion setting. The monsters are full of a flavour that can’t quite be achieved in a generic monster book. I know that I’m certainly more likely to use monsters from this book in my own games than many of the monsters from the hardcover bestiaries (such as the zoog, an obscure monster from Bestiary 3 that I just chose randomly). I highly recommend it to all GMs who use the Golarion setting, and even to those who don’t, but still want some new and interesting monsters!

While there isn't any hardcover bestiary this year, the people of Paizo at least gave us something. That something is the Innersea Beastiary and it is good. We get 5 playable races, 2 improved familiars, 5 powerful evil outsiders, 3 robots, 3 golems, 2 spawn of Rovagug, 2 dragons, 3 giant vermion, 1 giant, 2 Psychopomps, and 3 templates. Personely I think this book is worth it just for the 5 playable races, wich are the Lashunta, Andriod, Monkey Goblin, Ghoran, and Syrinx. I wish there was more info on these races, heck they don't even list were in the Inneasea region the Lashunta can be found. I do think the book suffers from the too many evil outsider syndrom and I do think there are creatures in there that weren't that world specific and could have been in a hardcover book. But despite some issues it is a good solid book for what 64 pages can really give you. I hope one day we will see more of these world specific books for things like distant worlds and the other continents. etc. but as long as it doesn't cost us a hardcover bestiary.

This year, there's no hardcover Pathfinder bestiary, so we get this to tide us monster fans over. While I really miss not having fourth big book of monsters, having this in the Campaign Setting line means we can have something that setting-agnostic Bestiaries don't: Golarion-specific monsters and ecology.

So, it's a much shorter but more focused monster book. What do we get here? Well, the book begins with an Android, a PC-playable race of cybernetic constructs. Yes, this the book where we gets robots, including the famous Annihilator Robot.

We also get a lot of things that have been hanging around in the background of Golarion since, like, forever. Lorthract. Mana Wastes Mutants. Water Weirds. Spawn of Rovagug. Petrified Maidens. Psychopomps. Lashunta. A plant PC race. Also, none of the monsters are reprints - it's all genuine 100% new stuff.

The artwork is, as usual, above awesome. This is an indispensable resource for running games in Golarion. Highly recommended!

So after getting this, doomsday door, and the mythic playtest all within 3 hours of each other I'm still reeling as I process it all, but of all of them this has been the true gem of them all by far. This book is absolutely packed with creatures of all cr, type, and need from giant magical beasts meant to wipe out continents to playable robots that have nanites that can activate and fuel their abilities just to start.

The art in this one is also amazing, I will admit that I was not a fan of the cover and was worried about whether this would be the artistic tone we would be getting through the rest of the book but I can say I was happily mistaken with beautiful art for each creature that really sells nearly every one of these creatures as compelling creatures that beg to be used against the next unsuspecting party of heroes from the new Kyton(thank you paizo) mother who lives in an iron maiden and transforms others into it's perfect art children to the sadistically cute monkey goblin that looks like a cross between a iguana, goblin, and chimp the art in this has been stellar and makes me wish they artists had their credit on the side of the page like those in the normal bestiary's.

Another amazing part of this is how much love many of the little used types and subtypes get. If you have ever wanted to do something with plants, sentient constructs, kytons, or psychopomps but felt like you don't have enough variety to make a whole campaign around them or even a decent sized dungeon look no farther. In this we get everything from kytons to a whole section on psychopomps ala the standard bestiary including an aside on psychopomp ushers (their equivalent of demon lords and infernal dukes). Even basic creature types like the vermin type get some love with a giant preying mantis big enough to eat wyverns and treated as sacred by the red mantis assassins with a stat block that makes it so much more compelling and dangerous then just a giant preying mantis.

For those of you who play exclusively in golarion the bios really help sell you on the connection each of these creatures has to the world from the aforementioned mantis and it revered position to the red mantis to the orocni, a new monstrosity from the fleshwarping vats of the drow. Each just feels like it fits perfectly in the little niche it was designed for and for that I thank Paizo.

Finally we get 4 new "playable" races listed in here that I wanted to give special note to. For those who had wondered about them they are all awesome each compelling in their own way from the nanite infused android to the race of plants that literally evolved from a batch of magically created plants meant to feed a nation. Each one has a wonderful amount of detail giving you plenty as a player to build off of and as a gm to integrate them into your own world be it golarion or home brew. The new racial abilities they have are wonderfully flavorful (literally one of them has delicious as a racial ability) and unique that I wish we could get an expansion for the race builder with more ability options like these. Speaking of the race builder each one has a point break down of each races point spread and the rp each ability is worth, perfect for the gm who may want to snag one of their abilities to use for that race that's been rattling around in your head and wanted to know how paizo balances it out.

So in short if you are a fan of bestiary's and your annual catalog of monsters to destroy your friends and PC's with you need this the work is just amazing and you won't be disappointed.
