Divinity Stone

A Divinity Stone is an extremely rare item and is considered to be one of the greatest historical treasures throughout the world.

Description
Divinity Stones are crystals that emit a pale blue light. They are formed when large clumps of mana pool together and crystallize over the span of 1000 years. Then, after several centuries, the saturated mana is liquefied and secreted as a potent healing elixir called "Ambrosia".

Although most Divinity Stones are formed naturally, they can also be artificially created by a person or persons that possess an extremely large quantity of Mana, and pool it over a extended period of time, though not nearly as long as the time it takes for them to form naturally.
