If your world has that feature. 167 does not have it, runecrafting, 4th cities and others.
Use the orc ears in the Sage's Tower to get legendary gear, it will take a lot of orc ears but if you save up and should they have them as a monthly reward sign in each day until you can get the reward.
World 167 does have Orc Ears and orc ear exchanges. I has since before Oct 2014. From what I've seen, though, only an exchange for Radagast's Staff and Gandalf's staff are available, outside a newer exchange for Bard's Black Arrow I from Lake Town.
