Blessed Jade

Blessed Jade was a substance closely resembling jade but far more powerful.

Appearance
It was created somehow in Yomi, roughly the same color as jade, the same hardness, the same workability, but it glowed with a strong light the color of newly-risen grass. This substance was incredibly rare, only a handful of pieces existed in Ningen-do.

Abilities
It could never be corrupted by Shadowlands Taint, so anyone who carried a finger of blessed jade was protected from the Taint indefinitely. Its rays caused great pain to Tainted creatures.
