Green Crystal Cluster

"A type of "crystallite," within which dwells a mysterious power. This specimen exhibits an extremely high degree of purity, distinguishing it completely from normal crystallite. It can enhance the mental power of the user to the furthest extent conceivable, and equivalent specimens have only been confirmed a few times throughout history. Mental power enhanced via this ultimate form of crystallite rivals that of the gods themselves, and those who possess it could conquer any fear or brave any calamity without much effort."
