The quest you must complete to get this is Master of Potions in the Cenarion Expedition area of Zangarmarsh. These don't sell as fast, but they do sell, and the barrier to entry for the wow gold market is higher than it is for the bread and butter flasks for wow gold. Potion mastery is the last option, and (you guessed it!) it allows you to proc additional potions. One important thing to note: if you change your mind and want to switch, you just need to pay 150g and won't have to do the quest again. Potions are another big seller on raid nights. Most people like to have a stack of something or other on them when they're doing their end-game raiding or PvP. Guess what?

Raiders are your biggest wow gold trade market for flasks and elixirs. Obviously, this means that your big nights will happen on the instance resets and weekends, when most people are in raids. I find that there's more competition on weekends, though, so focus my efforts on Tuesdays.You will see some sales if you list Flasks of Stoneblood for tanks and Flask of Pure Mojo for those classes that need mana regen; however, not in nearly the volume the first two will see. You should also consider doing your Northrend Alchemy Research every three days until you have all the elixirs. As with all products like this, make sure you remember to vary your stack size when you're selling them. These absorb damage of a particular school of magic but are rarely called for on the AH (at least when I checked last).

Your wow gold choice between these specs should be based on what you see yourself doing the most. If you make a lot of flasks but only transmute your daily epic gem, the extra yield on your flasks will be more profit than extra epic gem yield. The good ones are discovered by Northrend Alchemy Research again. Every three days! Don't forget!There's a much longer list of potions that may sell, but these are the primary ones. Also, there's a bunch of really specific resist potions that are rareish drops off of specific mobs in Icecrown.
