In-game description
"This ghastly armor was taken from an orc camp destroyed by barbarians. Instead of standard metal rivets, like normal studded leather, this orc leather is instead laced with hundreds of fire hardened bones. Finger bones, ribs, and skulls cover the armor, acting much like the traditional metal rivets. Powerful orcish enchantments give the armor special resistance to missile attacks, but the repulsiveness of the armor reduces the wearers charisma."
