Frostglaze Crystal Effects and Basic Information

Frostglaze Crystal	Rarity	4
	Type	Quest Items
	Effect	None

A glaze crystal produced in the depths of The Chasm, this special Glaze Sand Crystal ore was one of many scattered about during the battle against the giant ruin machine. Glaze Sand Crystal ore is a regional specialty of The Chasm, but this one is different from the rest.

Under the radiance of the blue crystal and the power of the Abyss, a strange spiral pattern has emerged within this stone, and it is cold, almost chilling to the touch.

This once smooth crystal has been transformed into this shape by the great might that descended from the heavens and the miasma that arose from the earth's depths — and perhaps the form it has taken is itself a warning unto mortals. If the interaction of these forces alone could twist stone and metal thus, if that ordinary heroine was truly able to witness the end of the pitch-dark path, how would she have faced the discovery she would make?
