Within this tome of terrors you'll find pitiless psychopomps and blood-drinking nosferatu, insectile formians and faceless nightgaunts, and even unique mythological horrors like Spring- Heeled Jack and Grendel himself.

The Horror Takes Center Stage....


This edition of the Bestiary series brings all the worst nightmares, not found in a traditional fantasy setting alive! Despite the horror feel, they work in any genre you might be playing. By far my favorite of the Bestiary series! The sheer creativity of the Paizo team explodes in this awesome collection of crazy!

An RPG Resource Review


Herein is a fine and fascinating array of monsters, most with supernatural aspects and worthy of songs and legends... indeed it is suggested that to make the most of them you should be also using the Mythic Adventures rules. Fitting adversaries for those who fancy themselves as such legendary heroes, perhaps...

The Introduction is mainly explanation of how each monster entry is presented, complete with handy icons used to enable you to tell at a glance the creature type and the terrain and climate that it favours. These are supplemented by appendices that list them by CR, terrain and so on thus enabling you to populate a chosen area with ease. Other appendices deal with special abilities and other details, including a fascinating section on monster creation, another on monster advancement and one on monsters as player-characters.

The main bulk of the book is composed of an alphabetical listing of the monsters. Each comes with a colour illustration and stat block, with plenty of detail and description to enable you to work out suitable uses for it and how it will behave when encountered by the party.

Beginning with the abaia, an eel with a strong regard for the environment which acts as guardian to a body of water... and turns quite nasty if you do not respect the lake it inhabits (it doesn't mind people who take only what they need, it is those who abuse nature that upsets them), there follows a fascinating array of creatures.

The almiraj, for example, looks like a cross between a rabbit and a unicorn, but it's no fluffy bunny! If nothing else, anything slain by its horn is turned to stone so if the poor almiraj wants to eat whatever it has attacked (it's apparently a carnivore), it has to eat its prey alive.

One of the weirdest is the colour out of space. This is an eerie radient incorporeal ooze that leaches life out of its surroundings until it reaches maturity, at which time it departs into the interstellar depths from which it came. If that's not enough for you, the Great Old Ones are here, so if you wish to combat Cthulhu or Hastur or the like, now you can... if you dare. Most have cults associated with them, details of which are also given.

If it's monsters out of legend that you want, there are beings such as Grendel, if you prefer more mundane ones there are gremlins or even giraffes! Undead too, and an alchemist's error called a hungry flesh, a giant ooze. To cap it all, how about an immortal ichor, which is an intelligent mass of blood from a dead evil deity...

This is indeed a collection of monsters rich and strange, ones whose very being deserve a song or story, never mind those that will be written when heroes defeat them in battle!

Lots of fun new monsters!

Read my full review on Of Dice and Pen.

Bestiary 4 contains over 300 new monsters. All the monster types are represented, although some more than others. There are many of the standards found in every Bestiary—new dinosaurs, devils, dragons—but also many unusual and bizarre creatures. It has provided me with lots of new options to throw at my players, and that’s always a good thing.


The Bestiary 4 for the Pathfinder Roleplaying Game has been one of the more favorites of the Bestiary series for me and I'd like to take a moment to tell you why.

To start, the Bestiary 4 has added everything from new types of fey to additional golems as well as the more prominent and popular Kaiju, Great Old Ones, and Empyreal Lords. Paizo's inclusion of these creatures that've gone on to become pop culture legends in their own right is a direct result of the designer's dedication to getting their monsters right. The Bestiary 4 is an awesome sourcebook and stands right up there with the Bestiary 3 in terms of 'fantasy verisimilitude,' hardening gamers resolve against such villainous foes as Cthulhu himself.

Not every book is a perfect image of idolatry however and the Bestiary 4 is no exception. While it's true that this book is littered with new baddies for your players to chase and new races for their characters to face, it is also bogged down with what seems to be an over-saturation of multiple page monsters. This isn't necessarily a bad thing, but it does seem as if several of these creatures could've used a proverbial trimming before being posted.

If you don't mind a bit of length though and you want more vile beasts for your players to square off against then the Bestiary 4 is yet another wonderful book to add to your collection and one that comes Five-Star recommended by your Severed Ronin.

You probably know if you need this


This is a good Bestiary. I'd personally put it up with Bestiary 3, with both having a good mix of classic, mythological, and completely new monsters.

There's a bit of a horror them and a bit of a mythic theme, but neither is overwhelming. If you're looking for a whole book of mythic monsters, this isn't it. If you're worried the whole book is mythic monsters, there aren't that many in practice.

For me, the evocative flavor on the high CR creatures pushes it over the top. The demon lords, empyreals, and great old ones really feel like epic creatures.

If you're sure you don't need any more monsters... don't buy this book. That said, I wasn't sure if I needed any more monsters and was definitely impressed by this.

Short Version: These are sweet monsters, but only you know whether you want more monsters.
