A Crystal Ball is a magical tool used by Witches for surveillance purposes.[2]
Description[]
Through the use of a Witch's Magic medium (such as Medusa's Snake), the user of a crystal ball can conjure an image from a long distance and observe an event as well as also being capable of broadcasting and receiving audio.[3]
In the non canonical Monotone Princess videogame, it is revealed that the Crystal Ball are created from Broken Crystal Pieces and are items that can be collected as part of a quest.[1]
