As a part of the 60 Destiny quest, you are forced to go into a cave in thunder river. If you follow the path of the cave, you will come to a boss named Kurbankohl.
He can drop a blue bow, 84.6 dps +5 bow range tapheath/stam, and 1% fatality chance, or a 1hb/1hs with +1% fatality chance. 1.5 damage, .2taphealth, .3 tap stam.
If you do the instance reset trick, you can pretty much farm this over and over, or at the least every day, when it resets. The results seem to sell for a decent amount on the AH right now, 50sp for the bow, and as low as 5sp for the 1hb.
The instance is also meant to be a single person instance, so it is unaffected by the boss nerf in the latest patch.
Happy Hunting!
