Like the other Call of Cthulhu Keeper Decks, this decks provide new layers to plots, enhance the story, and provide quick access to an array of fiendish foes.

A Plethora Of Mythos Fiends

Over 60 monsters detailed in the Malleus Monstrorum are presented here on their own individual cards, with all relevant game information on one side, and evocative artwork on the other. Use the cards for quick-reference during your games, and as a handy image to show your players exactly what their investigators are facing!
