When you're exalted w/ Cenarion Expedition, you can buy the Flask of Distilled Wisdom Recipe from Fedryen Swiftspear in Zangarmarsh.

This costs only a few gold (4) and is NOT BOP!

However, it does require you to be CE Exalted to learn it - but most people don't understand that.

So you can buy a few of these for a few gold and resell them for up to 100g depending on your server.

Here's a nice circuit for farming vendor trash of the birds in Deadwind Pass. They drop 4-6 pieces of trash per kill, and some of those stacks of 5 sell for up to 60 silver. I made about 2.5g in 5-10 minutes of lolligagging around trying to find the circuit. You could easily makes tons off this.

Runecloth can be a !@#$%^&* to get when there are other people taking your mobs. one of the most farmed areas of WoW is Kel'Theril in Winterspring. the suffering highbornes are renowned for their runecloth drops & assorted rare drops.

Go to Azshara.

Its nothing too "secret," but if you don't know this, it may prove to be helpful to gain a quick daily 10-15 gold. The reccomended level would be 55-60. At 55-58, this is even a good grind spot, as the mobs are easy to kill.

Ok now to the information. Its simple! Just go to Winterspring, and kil these:http://wow.allakhazam.com/db/mob.html?wmob=7524
