Khadgar’s Whisker is an early 40s herb that you will find in abundance in the plaguelands (similar to Liferoot and Sungrass). It’s a great herb to farm because you will find a huge variety of herbs while you farm it. Unfortunately, Khadgar’s Whisker itself is usually only worth 10-30 gold per stack. It also sells best in stacks of 5 and 20. Always check your realm’s prices before going out of your way to farm an herb.
You only need to have your Herbalism skill at 160 to collect Khadgar’s Whisker but you should be at least level 40 before you go out to farm it (depending where you go).
Update: You can make a lot of gold with Khadgar's Whisker, but if you want to step it up and make thousands of gold you should read my personal favorite guide.
Where to Farm Khadgar's Whisker
Farming Khadgar’s Whisker in Eastern Plaguelands
Absolutely the best place to farm Khadgar’s Whisker is in the Eastern Plaguelands. It is found in great abundance here along side two other valuable herbs: Liferoot and Sungrass. Stay between the cliffs and away from the shoreline to find the most Khadgar’s Whisker. Follow this farming route for the best results:
Farming Khadgar’s Whisker in Western Plaguelands
The second best place to farm Khadgar’s Whisker is just to the west in the Western Plaguelands. Similar to Eastern Plaguelands you will find KW all over the inlands along with other herbs, around the farms but away from the shores. If you want to make some extra gold while in WPL, circle the lake around Scholamance to Farm Liferoot before you leave. Follow this farming route for the best results:
Tip: Have you ever wondered how players have so many level 85s or how they can level an 85 so quickly? I use and strongy recommend Zygor's in-game leveling addon which will enable you to level in 5 days of played time. You can find a free version of it here.
