Red Crystal

"A type of "crystallite," within which dwells a mysterious power. This specimen has a higher degree of purity than normal red specimens. It has the power to further elevate the user's attack capabilities, but sudden use of such a large crystal may damage the body, so it's necessary to acclimate the user with normal crystallite first. Because this is a very valuable item, it is difficult to obtain unless you happen to be a veteran adventurer or a high-ranking general."
