As expected by everyone, the prices of Maelstrom Crystals have plummeted with the release of the quasi-farmable ZA/ZG heroic duo. Prices on Auchindoun have a floor of ~400g but it can creep up to 850g depending on availability. As is often the case however, just because material prices have gone down, that does not mean the prices of finished products need follow. At least not yet.
If you have a max-level enchanter, I suggest looking at the high-end scroll market.
I am talking about big-ticket items like Landslide, Windwalker, and Power Torrent. I am also talking about things like the wrist enchants. The weapon enchant patterns take around 2000g to purchase with Maelstroms at 400g, which is a reasonably expensive barrier to entry, keeping competition low. But just because Maelstroms are 400g does not mean you have to price them accordingly. Landslide might not be going for 26,000g anymore, but a "reasonable" 6,000g is still a particularly ridiculous margin now that Maelstroms are low. This is a sweet-spot time in terms of high-end enchants, insofar that everyone knows Maelstroms are less valuable than before (although still nothing to scoff at) but before the greater server groupthink expects weapon enchants to be cheap.
And as I mentioned in New Crafting Paradigm and/or Using the AH as your Bank, do not forget to put your leftover supplies on AH while waiting for the scrolls themselves to sell. I had four Maelstrom Crystals left over after making a Windwalker scroll and I simply undercut someone in the mid-level of crystal prices. Next day?
Flipping 400g Maelstrom Crystals for 650g might not be particularly glamorous, but that 250g is damn far more than I have ever made trying to sell things like the buff potions that I am tempted to just vendor out of spite at this point. Mythical and Mysterious? Sell well. Other potions? Not so much.
One final thing that I will drill into your head at every available opportunity: I highly recommend never crafting something that you could not eventually use. This applies more to the high-end scroll market or other markets that require steep up-front costs than, say, cut gems or potions. My first Maelstrom Gambit was actually a scroll of Windwalker that I can up and enchant my tank's weapon with right now if I felt like it. Merely knowing that fact gives me the psychological freedom to price it more aggressively (e.g. at the upper end of the price curve) without worrying about what happens if my gambit "fails." Worst case scenario: I (likely) have the cheapest Windwalker scroll available anywhere. Conversely, if you make a Power Torrent scroll and have no spellcasting toons, you might end up getting into undercutting wars with someone in a race to the bottom, or maybe discover there appears to be no market for the scroll above the cost of mats. Stranger things have happened, but this sort of uncertainty period is precisely what we will be capitalizing on.
