Barbatos: Is a very interesting spirit with a far different feel then most. He is not one to make small talk, or hang around for extranious reasons. When you call Barbatos I have found it is best to state your desire up front and give full details. Barbatos also does not like to be called for no reason. Even when one sets a light for him, tell him what you are after.
