It was when I was thinking about Him, that He appeared to me while in a food cafe telling me that He can teach me how to talk to animals; the prospect of doing so seems “cool” and invaluable, but personally impractical for me. So no dice. This is more for recordkeeping purposes; Caïm is Lunar (17° in Cancer- stands for restriction) & working with Him will not be easy, as success will not happen in a smooth manner. His seal is next to the description in the Goetia. Besides, He isn’t the only one that can do this, as Barbatos (another Lunar, why doesn’t that surprise me since most Lunar spirits in the Goetia deal with languages) is also described as being able to teach one this.
