Copied from Vile's Golden Auctions: Farming Infinite Dust
It is a common knowledge that most of the professions in the game are made so that they can compliment each others, well to be honest Blizzard are kinda leaning away from that model as they are trying to make each profession as independent as possible but this is not the point here. Anyone that has leveled enchanting in the past, or is maybe leveling an enchanter now knows that it is a rather expensive profession to level and especially when you get to the Northrend level of materials and you get to be in very short supply of Infinite Dust.
There are a few ways to go about the acquisition of Infinite Dust, but by far the most profitable way is by mixing up the two top end professions, Jewelcrafting and Enchanting.
The way to actually farm Infinite Dust from Jewelcrafting is very simple, heck it's the predecessor of today's Obsidium/Elementium Ore Shuffle, but to be more precise you are going to be making rings and necklaces yet again. You will need 4 resources which happen to be very cheap, and the best part is you can buy them straight from the AH for almost next to nothing for most of the time.
The resources that i am talking about are the common gems that you get when you prospect the Northrend equivalent ore, and those are the Chalcedony, Bloodstone, Sun Crystal and Huge Citrine. If you check your auction house you will notice that most of the time they are moving for abysmally low prices of some times being as low as 2g per gem. After you have obtained the gems you need to get some Eternal Earth that you can shatter so you end up with the Crystallyzed Earth that you will need as well.
So now that you have purchased the said gems and Eternal Earth what do you do that will be worth calling it Infinite Dust Farming ? Well you take those and you make them into Bloodstone Bands, Crystal Chalcedony Amulet, Crystal Citrine Necklace and Sun Rock Ring. After making these you need to ship them off to your Enchanter to do his disenchanting and you end up with your cheap supply of Infinite Dust. And another thing is that when you are disenchanting these you might end up with Lesser Cosmic Essences that you can sell or use as well.
Just so you get the idea on how important your stock is going to be to anyone leveling enchanting, to level past the threshold you will need 600x Infinite Dust and 30x Greater Cosmic Essences that you will get by combining the Lesser Cosmic Essences, and this is for a single guy alone. So you can see that the demand for this is rather high and the supply is always low.
In a future post i will give you an idea of how to further improve on the profit margin by investing some more time into the enchanting part of the whole deal, but for now i will leave it at this.
So, like always, keep an eye out for good opportunities out there.
