Well in a shocking develeopment we actually killed something that we can use to make a decent screen shot!  Making a nice change from Hydross's bracers or Magtheridons "bit of armour" plates, we downed Void Reaver on the first night of tries.

 After getting most of the people attuned Blizz then removed the attunements requirements (prob just as well really as we had a few swap out) meaning we could go into Tempest Keep last night instead of the planned raid later that week.  So on the last try of the night with respawns already starting in the room we just went for it and downed him.

 Loot was: 

[Pauldrons of the Vanquished Hero] - Aphadon
[Pauldrons of the Vanquished Defender] - Batou
[Fel Reaver's Piston] - Skypheonix
