From the publisher:
Hail stranger, dare you come and lay your eyes on your doom? Step inside if you can and bear witness to the foulest compendium the Forge has to offer! From across the seven domains, beasts and horrors have been gathered, dissected, and brought into the light of day. From the battle tactics of the colossal Sand Strider to the mating habits of the lowly Death Moss, all the knowledge you need to keep your thread of life intact is here for your taking. Come experience the bloodthirsty rage of the Karnos and the twisted machinations of the Palethian. No mortal danger required... except for maybe paper cuts.
The Oathbound Bestiary is the official monster compendium for the new Oathbound for Pathfinder. It is a companion to the core book (Oathbound Seven), and includes over 200 monsters: three distinct, re-envisioned, and revitalized versions of each of the classic Oathbound monsters, plus many entirely new creatures and tons of updated art, ideas, and stats.
