I've been farming brown treasure caskets in The Shrine of Ru'Avitau for days now to get a Terminus earring (skill up earring). I've gone through 8 stacks of Thf tools, received 60 geode and HQ geodes, over 2 stacks of Kindred seal/crests, 75 levels of prowess (including +4 treasure casket) and I'm about to lose all sanity.
Is this drop seriously that rare? I'm fighting Decorative Weapons in the area accessible from the "front door" to the shrine. Does mob matter?
