Shunsten

The rare mineral shunsten could be glass, but for its durability and natural, organic form. Its translucence makes it difficult to find in veins of ice and bone, and even more so in other lodes. But finding it is a hunter's delight — eating shunsten increases rage gain from each attack by thirty percent (30%) for up to a day.

Shunsten is named for its discoverer, Shunsui Azon.
