Divination is a power that is used to gain insight and secret information and to contact spirits.
It is one of the basic powers of witchcraft that all witches possess.
Overview
This ability allows user to gain information when channeled through arcane and mystical tools such as an Ouija Board.
This ability is not however very reliable as the tools can be manipulated.
Harry Greenwood, for instance, claims Ouija Boards are very vulnerable to tricksters and the Charmed Ones themselves were decieved by an Imposter Demon.
Bibliomancy
Bibliomancy is a branch of divination which allows the user to gain insight by using books (often of a sacred or magical nature) to obtain advice.
The Vera family's Book of Shadows also possess this power, which allows it to answer any question made within its proximity as long the answer is within its pages.
