GW Wiki says:
Farm the Vehjin Mines
From Jennur's Horde, cross through the mine work area, then head northwest to find 4-5 groups of Cobalt. When you hit the Behemoths turn Southwest for another 3-4 mobsI say: This is pretty accurate
Also, when you hit minotaurs and giants (south west), turn another way.
There is also a boss Cobalt here for your amusement.
You can get the 10 Talons you need for Nick in about two full runs tops (average about 5 Talons per run), each run taking about 15 minutes.
I used a SoS Solo Rit to farm the Talons:>
Ebon Vanguard Assassin Support (to occupy the Cobolt Scabara assholes)
>
Vampirism>
Bloodsong>
Shadowsong (can't hit what you can't see, hehe)
>
Pain >
Signet of Spirits >
Armor of Unfeeling (necessary as with any SoS solo farm vs anything above level 10)
>
Summon Spirits (using your highest Luxon or Kurzick rank if u have the skill from both faction
As you may have noticed, I didn't use a heal skill in my build.
You really don't need one, there is a rez shrine nearby...if you die....you die, no big deal.
Also, didn't bring Painful Bond-since they just remove it anyway.
All spirits=All damage
That's all,
