Pit-Forged Obsidian

Pit-Forged Obsidian was the closest thing to pure evil that the Empire had seen, the celestial counterbalance to Blessed Jade. It was found only in the Festering Pit of Fu Leng and radiated Shadowlands Taint.

Appearance
Pit-Forged Obsidian was a jagged black stone covered with sharp edges, which absorbed all light and heat. Any normal jade that came into contact with this material was immediately reduced to black sludge, and when blessed jade touched an equal amount of pit-forged obsidian, both materials were immediately destroyed.
