The Tome of Monsters is an interesting book of monsters for Pathfinder mixing creatures from legendary sources with entire new creations. Like any book of monsters, it depends on the campaign world how useful it will be. It has a variety of interesting beings especially among the fey and legendary creatures included and as a resource for new familiars.
The Tome of Monsters is a 118-page PDF (114-pages if you remove the cover, OGL page and a blank page) for the Pathfinder RPG written by Sean O’Connor & Katheryn Bauer with Connie J. Thomson & Robert W. Thomson and published by 4 Winds Fantasy Gaming.
The layout is primary traditional two columns, if you have looked at any book of monster for Pathfinder you will recognize the format and is fully book-marked for easy navigation. The cover is full color while the interior art is black and white with each monster getting it own illustration. The art quality is a bit variable however, some are quite well done, while others are a bit primitive.
The monsters presented range widely: in CR from 1/8 to 20 and in type. Some have shown up before in other versions, redcaps and scarecrows for example, but many are new and several draw upon legends from across the world. Those that are created from legends get a note about the source and some comments on the legendary creature. Some, but too few, get adventure seeds as well. A few of the creatures (clockwork familiars and ekatonkier) appeared in previous 4 Winds products but have been expanded on for this book.
It introduces a new type of elemental (aether) which are intriguing but not very well elaborated upon. Many new familiar creatures and possible animal companions are included along with four that are suitable for use as player characters (goatman, machlyes, neanderthal, and otso)
