is that the stuff from the slimes? dont forget you can pickpocket them. I think sometimes you can even pick one off them, then get one after you kill them.
It didnt take me that long, somebody else was farming them as well.
Then again i might be talking about something else.
My problem was they just weren't dropping. Probably 1 out of 10 pickpockets actually pulled a fragment. There were 2 other Rogues staying on the western side of the spawn area working on their's, which is where the hyppos are. So I was forced to head over to the eastern side with the 55-57 Rock Elementals and Giants, kinda made unstealthing a little less fun than usual >.<
Not by much, but it is. Besides, everybody should run ST at least once to learn how to deal with those large mixed groups. The sleep effect on the final boss can be pretty tricky too, and it requires some creative offtanking and agro dumping.
