WoW Retail, How To Farm Some Of The Rarest And Most Expensive Materials In WoW Super-Fast (Patreon)

EDIT 14/06/2020 Class trials are no longer offered Legion world quests. This technique can still be performed with Demon Hunters and alts.

The following exploit is very strong, even more profitable than the anchor weed exploit I wrote about here: https://www.patreon.com/posts/33595884 . However this exploit requires a little more patience and knowledge of the workings of the auction house.

In the Legion expansion Blizzard introduced profession-based materials which are very valuable relative to other materials. These materials still sell for a good price in BFA. This is because Blizzard made it very difficult to access these materials  outside of specific world quests. 

This gating restriction keeps the price of these materials high since the supply to the AH is very limited. For example, yesterday I sold 5 Felhide for 2525 gold, which took less than two minutes to farm.

It is possible to get around this restriction by using class trials. The following can be done in less than half an hour with practice:

1. Create class trial mage.

2. Use hearthstone to get out of the introductory scenario.

3. Fly to skinning and herbalism profession trainers and learn the basic skills.

4. Go to your faction's portal room and use the portal to Azsuna. 

5. There skin and herb everything around. (Edit: See comment below from Bryce Collins: You can skip gathering the 10 stonehide leather by instead skinning a cliffwing hippogryph and getting the stormscale sample quest. Instant bring to dalaran and get legion skinning )

6. You should receive quest items from doing these things. 

7. Complete the stonehide leather quest (you need 10 stonehide quest items) and turn it in at Dalaran (you will have to fly there). You should also have a herbalism quest which you should also turn in.

8. You should now have Legion skinning and herbalism. Go back to the Broken Isles From Dalaran and farm and herb till you reach level 25.

10. Quests should now open up immediately on the map which allow you to acquire 5 Felwort and Felhide. These quests only take minutes to travel to and complete.

11. Repeat 10. every time these profession world quests are up.

Felwort and Felhide sell for an average price on the AH of around 150 gold, meaning on average doing the two quests yields about 1500 gold in net profit. 

However, that doesn't really represent the true profitability of this exploit. I have often sold these items for more than 3x the average price.

 Many realms have either temporary or permanently supply deficits of these items and then you have an effective monopoly providing you expend relatively little effort on timing your sales.

Because this is a class trial play, you can also selectively target smaller population realms with low average supply and make much more than average price from sales. You should be looking to make at least 50K per hour invested from doing this. 

Also worth mentioning that if a world quest opens up near to a profession quest with a decent gold reward, of the "Kill single monster" variety, then it is generally worth doing that on the way. 

Building up an army of class trials to do time-gated content like this and alchemy transmutes is the single most profitable basic exploit you can use in the game.
