Electric Crystal Ball
An Electric Crystal Ball is a device that combines science and sorcery, which allowed Macbeth to control and utilize the will-o-the-wisp he summoned. [1]
History
After a quick retreat to his aircraft, Macbeth plugged the crystal ball into the aircraft's instrument panel. Once the will-o-the-wisp was summoned, Macbeth was able to not only track the spirit, but also listen and see whatever the Will-O-The-Wisp saw on his aircraft's monitors. ("Pendragon")
