Free WoW Guide: Farm 40 - 60 Gold an hour

All you need is a level 52-60 character, any class.

Go to fellwood and go to the north eastern most lake. Around the lake you will find Toxic Horrors. These have a 7% Chance drop of Essence Of Water and they can be sold at the Auction House for 10G EACH!

There toxic horrors are very easy to kill howver they do carry a pretty powerful poison.

You can find 4-6 of these an hour pretty easily, and they are very easy to sell since they are a reagent.
