Obtaining the quest items is very slow and aggravating. I finally got the blackened vial from a Broken Skull initiate after about 10 hours of farming. (non-continuous). I set up camp in the far corner of the sand room and single-pulled initiates and the odd roaming Furious Blackhand. I am a 58 shaman and was able to solo. Most of the Mobs conned light blue with an occasional dark blue adherent. You should definitely get Virtue before attempting this. The mobs hit for a cummulative 185 - 250 per turn.
Fortunately, the trolls have a very low agro radius. My technique for killing them started with casting root, slow, cripple, poison dot, disease dot, cold direct damage then let pet whack until root breaks and join in and beat on the troll while hurling direct damage spells. I always had gate loaded for those times when I did aggro a second mob or when I couldn't break the gate cycle of the adherent and was running out of mana.
Adherents will gate at about 20% and return with 33% health. As a Barbarian Shaman, I was able to use slam to break up their gate spell. When they return from the gate, they do not bring friends.
Furious and Vehement Blackhands reside in the Courtyard. You can kill them and move around the room as you polish them off or set up camp in one of the alcoves. As of yet, I have not gotten the broken skull blood or the pure blood.
The plus side is the trolls drops rubicite ore, nilitim's pages, various words, and some nice trinkets.
As some of the other posts say, you can get to the zone via the lava road, climb the wall on the right just past the bridge. You will need invisibility on unless you want to fight the fire elementals and the troll miner at the top of the wall.
