A scrying pool is a device capable of seeing elsewhere when filled with water. In the words of Heath Buckland, it's the "magic equivalent of Google". A scrying pool can be worked using a revelation spell.
Known scrying poolEdit
Alice Hartley's Scrying PoolEdit
Alice Hartley owns a metal plate that serves as her scrying pool.
The scrying pool was used when Alice was watching Andy Lau, while he cast a spell and got sucked up by a vortex.
When the gang went to Bremin High School to find a ley line intersection, Alice mentioned that the scrying pool informed her of the second talisman being at that location, and adding that "the scrying pool never lies".
