The first of our Inferno products! The 20 page Codicil gives details about the illnesses, maladies, and conditions that Adventurers are subjected to as they cross the Malebolge wilderness. The Codicil provides rules for diagnosing maladies, acquiring medicinal plants, and for preparing curative poultices and tonics. This product presents information about the maladies specifically mentioned in Inferno: Journey to Malebolge, information not repeated in the module text. The information in the Codicil can also be used easily by Game Masters in other settings as an alternative to generic RPG diseases.
