Location : Netherstorm. Go south-West to Manaforge B'naar
Objective: There are plenty of bloodelves from level 68-70 to kill.
Recommended level: 70, but anywhere from 67-70 is alright. (70 is best as you can kill them the fastest. Yes, common sense)
How it works: Well killing the blood elves clearly but, they die very easily. They drop roughly 10 silver per kill. Plenty of netherweave cloth and scryer reputation items (Sunfury signets and Arcane Tomes). Also greens and greys drop for to vendor, but its still a great money maker! I've been doing this on my warrior recently and it's great. After about 1 hours farming, i got 5 arcane tomes, 100 sunfury signets, many stacks of netherweave cloth, and about 25G worth from the silver. Also the greys and greens add up so i got about 70G all in all from the vendor and silver. And selling The arcane tomes and sunfury signets and netherweave, all-together i got about 250g.
