Andorhal Silk Cloth Farming in Western Plaguelands
Andorhal is split into two different sections, one where there are Horde NPC's battling the scourge and another where Alliance NPC's are battling the scourge. Depending on your faction will obviously be where you farm in Andorhal. Since the NPC's of the opposite faction do not drop loot when you kill them it is best to just stay away from them rather than waste your time killing them for literally nothing in return. With the only being able to kill in certain areas of Andorhal aside, since all of the NPC's are already engaged in combat it makes this place an excellent area for farming.
Whenever NPC's are in combat with one another you can jump right in and kill either of the opposing NPC's even if they are at half health and still get all the loot. You won't get full XP, but we aren't here for XP after all. Keep in mind, like I said earlier the opposing faction's NPCs will not drop loot. So don't get all mad and say "that isn't always true because the alliance NPC I killed in combat didn't drop anything!"
Since this is a quest area for both Alliance and Horde you may run into some PvP here, unless of course you play on a PvE server. Some people may be bothered by the ganking but others will be like "Oh boy a chance to gank the other faction! I'm all over it!". Now, as for what part of Andorhal is friendly based on your faction, the Alliance actually own more of Andorhal than the Horde. You would assume that it would be an even split but it isn't. Below are two pictures to help show you how Andorhal is split in half.
Silk Cloth Farming Locations
Besides Silk Cloth there really isn't anything else in Andorhal. On the far outskirts of it you will find some Iron (to the far east or west by the rocks surrounding the river to the south) but inside of Andorhal you won't find anything at all. No herbs, no mines and I didn't see a chest when I was farming here to write this guide or make the video. However, if they still held true to the original Andorhal then I wouldn't doubt there being a chest somewhere in here, the original Andorhal had a ton of chests.
