Now Available!

Sandy Petersen’s Cthulhu Mythos is the most comprehensive guide to including Lovecraftian elements in your Pathfinder Roleplaying game, written by the author of the groundbreaking Call of Cthulhu role-playing game, and developed primarily by James Jacobs (creative director of Paizo) and David N. Ross.

This massive 512 page tome contains over 100 monster stat blocks, dozens of which are Cthulhu Mythos monsters that have never been described for Pathfinder – including new rules for interacting with 25 different Great Old Ones and Outer Gods (they are much more than a simple encounter!).

This tome is much more than a mere bestiary, however. Inside you will find new rules for Insanity and Dreams; 40 new spells and 30 Rituals – a new magic ruleset; dozens of mythos items and artifacts; dozens of Mythos cults detailed; and four new player races from Lovecraft’s universe – Dreamlands Cats, Mythos Ghouls, Gnorri, and Zoogs – as well as new character options, professions, feats, and race options for them.

If you like Cthulhu, Pathfinder, Monsters, and Madness, you need this book!

NOTE: You will receive a download of this book FREE with purchase of the physical book – any edition!

    I ordered a physical copy of the Cthulhu Mythos book on 12 September, which comes with a free copy of the pdf. When I made the order, the link to the pdf didn’t work, and I had to contact customer support and have them email me the file. They did so promptly, which was good, and the product is fantastic, exactly what I was hoping for.

    However, the physical copy arrived this week, and I was shocked to learn that I had to pay a $44.23 C.O.D. charge to UPS for importing it to Canada. There was no indication of this through the ordering process before, during, or after. I have ordered books from the US frequently and never had to deal with this before, and if there was going to be a C.O.D charge, I was given some sort of notice beforehand. I would give this a 5 star review, were it not for the fact that I ended up paying almost double what I thought I was going to.

      Hi Eric,
      Sorry to hear that – it was certainly a mistake on the part of our shippers, as we always send DDP to Canada. Please contact our support again and we’ll get that taken care of for you!

    My friends and I have been playing Pathfinder together for nearly a decade. I recently started DM’ing a Lovecraft-influence Horror/Occult Pathfinder Campaign and this book is EXACTLY what I was looking for to help me in building the world and encounters! Each page is filled with lore, the artist depictions are visually stunning, and Petersen’s penmanship is the perfect addition to any Pathfinder campaign with mythos-inspired creatures, locations, and encounters. This book is a must-have for your game!
