I made this Silk Cloth Farming guide to help out players who want to farm the cloths instead of buying them from the Auction House. I decided to search for places with a high density of mobs that I could kill and drop Silk Cloth. I traveled around Azeroth, and after a while, I made a list of places.
There were no major changes to Silk Cloth drop rates, so this guide can be used for Cataclysm Classic and Retail WoW.
Silk Cloth
Feralas (Alliance or high-level Horde)
These mobs have much higher respawn rate in Retail WoW, go to Thousand Needles instead.
Grimtotem Marauders near New Thalanar drop a lot of Silk Clith, and the respawn rate is really fast, you will never run out of them.
Note for Horde players: There are a lot of mobs here that are hostile to horde players and drop no loot, so lower-level Horde players should not go there, but for higher-level Horde players, it doesn't matter as long as you have some kind of AoE ability, you will one-shot mobs anyway
Thousand Needles - (Horde)
Westreach Summit at Thousand Needles is almost identical to New Thalanar, but the mobs are more spread apart. Grimtotem Pillagers are battling with Summit Defenders and they instantly respawn after the number of mobs in the are getting low, which means you will never run out of them.
Note for Alliance players:This place is close to a horde town, so lower-level Alliance players should not go there.
Badlands
The Dwarfs and Troggs inside the cave that leads to Uldaman drop a lot of Silk, so this is a great alternative if you can't farm at the previous places mentioned in the guide. Don't forget to clear the mobs outside the cave too! There are a lot of mobs up on the cliff to the right of the cave entrance.
The respawn rate is not that fast, so if you have a class with high mobility, you might clear the mobs too fast and have to wait for respawns. (if this is the case, you should clear Uldman once while you wait for respawns)
Dustwallow Marsh
Blackhoof Village in Dustwallow Marsh is also a decent place. The mobs drop 1-3 Silk Cloth and respawn quickly. You can keep running from one end of the camp to the other and farm Silk Cloth.
When you have enough Silk Cloth, go to my Mageweave Cloth farming page.
