Mythos Monsters — Lovecraftian Horror Bestiary for Pathfinder RPG

Cosmic horror has always lurked at the edges of the best Pathfinder campaigns. Mythos Monsters brings the full weight of H.P. Lovecraft's Cthulhu Mythos to your Pathfinder RPG table — a comprehensive collection of eldritch creatures built for classic Pathfinder, complete with sanity rules to make every encounter feel genuinely harrowing.

From the depths of R'lyeh to the far reaches of space, these creatures aren't just high-CR threats. They're tools for building campaigns where the horror escalates, where players start to question what they know, and where the final confrontation with a Great Old One feels earned and terrifying.
