Elf Bone

Galadhrim Elves and  Wood-elves, when killed, will sometimes drop an elf bone. They yield the same amount of bonemeal as a human bone, meaning that  evil players can use them to grow crops for food (although Sauron's hordes are more often found burning crops than sowing them). An elf bone, like other bones, can be sold to Orc Traders (and Uruk Traders) for one silver coin, meaning that if you kill enough elves, you can have a steady stream of ill-gotten wealth.
