Jade

Jade is a precious stone varying in color from milky white, various shades of red, light green to dark green. In Rokugan the green variety is found almost exclusively with most mines being found in the western and southern Crab lands. The stone naturally posses innate resistances to the corruptive shadowlands taint, it can temporary shield a wearer from being infected, it can be crushed and placed into an open wound to help fight direct contact with taint, and it can be infused in weaponry to inflict more damage with a blows. Jade has been a staple item of the Crab Clan armies since its nature was discovered. Since the Battle of Oblivion's Gate the Empire has experienced a dangerous shortage of jade, its use is now heavily restricted, and it has become exceptionally difficult to acquire in Crab lands, and even more so everywhere else.
