A lot of people seem to have issues using pendulums to get specific answers, to identify a spirits species or to find out things about who they are or how they look so here are some basic questions that can be answered with yes no or maybe. Honestly this is all just like playing that game Guess Who.
What Are You
Are you a ___? : pretty basic just go down the list of all the things you can think of until you either run out or get a yes.
Are you a Death related spirit ?? (Dullahan, Grim, Reaper, Banshee, etc)
Are you an elemental spirit? (fire, earth, water, air, ice, snow, lightning)
^^this is usually a subcategory. For example if you get water and faerie you are looking for a species of fae connected to water
Are you connected to a specific religion or culture
If yes specify which and then go through the list? religion? Abrahamic? Culture? Irish??
This is where shit get touchy so be respectful of other cultures and their spirits okay?
Are you something I already work with?
For spirit workers with a large spirit family this could be helpful
If you get a maybe it likely means that they are but a different type. Say you get a maybe and when you go through the types of spirits you work with you get a maybe for vampire. They are likely a different type of vampire than the one you already work with
