The recipe is a reward from the quest Sandra marches

The recipe is a reward from the quest Sandra marches in the Burning Crusade, which is the reason that a large portion of black kids don't have any idea about this recipe. It is possible to use this method to combine engineering with either mining or herbalism. You can also gather clouds while flying. Or you can find a location with several gas clouds that are next to each other and connect them with a gold farm or farming mob WoTLK Gold . My personal favorite gold farm in Wrath actually has exactly that.

It blends a mob farm with clowns, which can enhance the gold prepper's effectiveness massively. And all of these types and locations are described in my classic wrath gold guide, which is once three times linked down below way. Next is rogue pickingpocket farming. It's more an orange type of farm. It can give you 200 gold per hour, or provide you with 1500 gold per hour. It's all about your luck. However, this is an extremely fun way to mine gold. And it is incredibly profitable.

There are no requirements for professions at all. Because you're not actually killing anything, it won't require any equipment either However, it's locked to one class only aka Rogues. That makes this kind of style of creation a bit special. One form has been found to be actually incredible, which is found inside Sholazar Basin all the way up north up the mountain to pickpocket the zombies. That being said I am thinking this could be because the rift is way over farmed. However, there are many places in Northland in which you can  buy WoTLK Classic Gold earn many gold coins from pickpocketing.
