From publisher blurb:
For GMs in need of more beasts! The Run Amok Bestiary contains over 30 new monsters for your Pathfinder Roleplaying Game. Drawn from real-world folklore, legends, and Run Amok Games products, this collection covers a wide range of creature types, terrains, and challenges. From tiny pumice warriors to the crag-dwelling mountain wyrm, from city streets to the cold and windswept plane of Leng, from ancient vampire-like horrors to clockwork-driven automatons, the Run Amok Bestiary contains dozens of challenges for your PCs. In addition to monsters ranging from CR 1/2 to CR 19, four new templates allow you to customize creatures in all new ways.
More than mere monsters, the Run Amok Bestiary includes new PC-appropriate races, familiars, animal companions, and numerous adventure seeds to bring these creatures to life!
