The named slave npc that drops this document has not been spawning. I have cleared the entire zone of slaves several times with no avail.
This is my third time doing the epic offhand quest.
The first time the document dropped of random slaves, this was easy and not time consuming.
The second time the new named NPC had been added that drop these documents, all nammed were easily spawnable and did not take to long to complete the quest ( All of these NPC have like 0 HP btw and die in one hit)
On my current third time doing this quest i have been in this zone killing every slave of all types i can come across. If the npc that drops this is supposed to be random i think its spawn rate should be bumped up quite a bit. Or possibly only one can be up at a time and he spawned under the world or such.
