Unleash a world of monsters! Bestiary 3 presents hundreds of new creatures for use in the Pathfinder Roleplaying Game. Within this collection of creatures you'll find grave knights and savage cyclopes, kappa and colossal kaiju, clockwork killers, mysterious sphinxes, imperial dragons, and so much more! Yet not all these monsters need to be foes, as fleet-footed sleipnirs, cunning vanaras, whimsical faerie dragons and more companions from myth and modern fantasy join heroes on the path to legend. In addition, new rules for customizing and advancing monsters and an expanded glossary of creature abilities ensure that you'll be prepared to challenge your players wherever adventure takes them!
