What are the three types of divination used by witch doctors to diagnose?

* Scrying: This involves gazing into a reflective surface, such as water, a crystal ball, or a mirror, in order to see visions or receive messages from the spirit world.

* Augury: This involves interpreting signs and omens from the natural world, such as the flight of birds, the movement of animals, or the weather, in order to divine the future or gain insight into a particular situation.

* Bone-throwing: This involves casting bones or other objects and interpreting the way they fall in order to gain insight into a particular situation or receive guidance from the spirit world.
