Purple Crystal

"A type of "crystallite, within which dwells a mysterious power. This specimen has a higher degree of purity than normal purple specimens. It has the power to further elevate the user's mental power, but sudden use of such a large crystal may damage the body, so it's necessary to acclimate the user with normal crystallite first. Purple crystallite is often carried by priests, but even the most high-ranking sage is unlikely to have many specimens as large as this."
