Demonic Translation is the power to read and understand demonic languages as well as translate it into English and other recognized languages.


In "Ambush", when Macy Vaughn and Harry Greenwood were looking for a spell that could take one's immortality — hoping to use it against Fiona Callahan, Harry is shocked when Macy came to him with a book as he realized that she was reading Illevaihcam (also known as "The Devil's Tongue").
