There was a bug on Varns that wouldn't allow SK's to loot the Flamberge. It is now lootable. Also he has been tweeked again so now he only hits for a max of 1300 at a whack. His DoT doesn't do as much dmg either. We killed him before when he was ubber twinked and hit for like 1900-3k at a whack. Needless to say wiped the first time but the second time we had a couple of bards and he was cake walk. He runs at low health also so I suggest completely clearing the room and having an off tank ready to keep the repops under control.
Just my 2cp
