Destruction & OrderEdit
Kill Deathwing (a level 40 Champion Giant Bat) in the Caverns of Terror at 44600,3000 in the Chaos Wastes. He can be found in the room furthest back. He has a chance to drop Deathwing's Fangs. If you get these, click on them for the unlock.
Note: There are two other champions there, Armaros Lifebane (lvl 40 Champ) and Raum Ravencloak. If solo it might be a good idea to try to kill these before Deathwing, so they dont add onto the fight. ~Lucrin
