Edit: Narf! I found one! Just had the wrong keyords -.-
Goto http://www.ownedcore.com/forums/worl...e-faction.html (Shado-Pan dailys bomb players of opposite faction.)!
My Explot part is still working.
Well, I think I found a thread about something similiar to this a few days ago but I'm not able to find it again, so sorry when I missed it.
When you are on the Shado Pan Dailie Quest [The Enemy of My Enemy... Is Still My Enemy!] you should also have the Quest [Assault Fire Camp Gai-Cho].
For the first quest you need to pick up some explosives (a maximum of 10 at a time) and throw them from you own mount onto the mobs in the Gao-Cho Battlefield.
While on the Gai-Cho Battlefield you are able to throw the explosives onto mobs (and even Players of the opposite faction) in the "Fire Camp Gai-Cho". The explosives will deal around 500k damage on mobs and around 350k on players, depending on their resilience.
Now to the exploit part:
While throwing the explosives on mobs in the Fire Camp Gai-Cho (you need to be in the sub zone "Gao-Cho Battlefield" to throw them), you will get credit to the kill and be able to loot the mobs or get honor from killing the players respectivly. Most of the time blizzard does not intend to let mobs drop loot when not killed by player abilities.
You may optimise the farming by doing this with a friend. One of you should draw all mobs to a place where the other one can bomb them. They have a nice dropchance on Spirit of Harmony and cloth. In around 5 minutes of bombing I got nearly 2 spirits
Happy farming! (or Trolling)
