With the October 29th reset, players can turn in their Nerub-ar Finery for further increases to their Severed Strands raid buff.
Nerub-ar Finery is a Warband currency earned by defeating bosses within the Nerub-ar Palace raid. This currency can be turned in at the entrance of the raid to receive the Severed Strands raid buff, providing a total of 4.5% extra damage dealt & healing done while inside Nerub-ar Palace.
To turn in your Nerub-ar Finery, look for the Anub'azal projection located at the immediate entrance of the raid. Players should see a blue question mark symbol over its head. You will need at least 16 Nerub-ar Finery to complete the quest and receive the buff.
