Odin, one of the most recognized symbols of the Treasures of Aht Urhgan expansion, a favorite avatar amongst summoners, and, perhaps most famously, the final challenge for those who faced the perils of the Hazhalm Testing Grounds for the Einherjar battle system. Sadly, as with many other enemies, the one difficult trials of Odin's Chamber are no more. However, to offer a new way for adventurers to test their mettle against a powerful, but familiar opponent, a level 99 version of the Odin's Chamber battle will soon be added.

 New key items, the Valkyrie's Tear, Wing, and Soul, which are required to enter this new battlefield, will be available through purchase via therion ichor, or through trading of feathers from the older chambers.

Let us know what you think on this new addition to Einherjar over on the ZAM forums!

• A new version of the Odin's Chamber battle for level 99 adventurers has been added to the Hazhalm Testing Grounds.
  • Entry Procedure: Trade a Smouldering Lamp to the Entry Gate after having aquired the designation "Elite Einherjar" and the valkyrie feather key items from each of the three Wings.
  *The Odin's Chamber and Odin's Chamber (Lv.99) battle occupy the same area. If one battlefield is already reserved by a party, a different party may not reserve either.

• The procedure for entering Odin's Chamber has been revised.
  • Trade a Smouldering Lamp to the Entry Gate while in possession of the valkyrie feather key items from each of the three Wings.

Players may trade a Valkyrie's Tear, Valkyrie's Wing, or Valkyrie's Soul to the "???" target in Hazhalm Testing Grounds to obtain one of three possible key items:
