After all this time, the Osseus Mace is finally in our Weapons Compendium. You can head over to the Weapons Compendium to view the details of the much sought after item.
Update: A few other additions. I’m adding all the different flavors of Elysa’s Favor. <strike>Right now it appears that Holtburg gives you the Armor version, Yaraq gives you the Strength version and Shoushi gives you the Endurance version.</strike> That was incorrect information, the results may be random, so there may be no guarenteed way to get a specific version of Elya’s Favor. The links above though are correct, they just do not relate to any specific town.
