What is the best method? I'm not talking speed runs or exploits. Just a legitmate way to gather tomestones for my Darklight gear. I just got my chest piece today after spending the past 2 days farming it 16 times between those 2 days in Amdapor Keep and I'm just hoping there is a better way that i'm missing because if I have to run amdapor keep another 16 times for one more piece of gear i'm gonna cry. ):

I appreciate advice you guys can offer.

TL;DR What is the best farming method?
