The most comprehensive guide to the Cthulhu mythos ever written for 5e fantasy.

Fans of Cthulhu will love this massive tome from the author of the groundbreaking Call of Cthulhu role-playing game. Sandy Petersen’s Cthulhu Mythos is the most comprehensive guide to including Lovecraftian elements in your Roleplaying game.

The book contains over 100 monster stat blocks, many of which are Cthulhu Mythos monsters that have never previously been described for Dungeons and Dragons 5e. New rules are included for interacting with 25 different Great Old Ones and Outer Gods.

More than a mere bestiary, inside you'll find:

new rules for Insanity and Dreams

  • 40 new spells
  • 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.
