This is a great spot for Amber-shards, as well as cloth. I would also recommend a Potion of Luck for extra cloth drops + ore.
I was using the Klaxxi Buffs :
- Raining Blood - Have to have unlocked the Prime, Xaril the Poisoned Mind (Revered)
- Battle Hymn
Screenshot of Farm spot:
- 28 stacks of Windwool Cloth - (I am a Tailor)
- 5 Ghost Iron Lockbox
- 23 Dread Amber Shards
- 54 Motes of Harmony
- 14 green quality Items
Not bad for mote farming as well.
