Specter Tears

"A teardrop-shaped crystal within which dwells great power. It carries the essences of both good and evil and its power exceeds human understanding. Its existence was once doubted, but it was confirmed as more than just a legend several decades ago. A "specter" is a type of legendary creature halfway between beast and spirit, and the first discoverer of this crystal claims that it was made by such a creature, giving the crystal its name. This claim, as well as the existence of such "specters," has since been debunked."
