I shared a tip on the site back on December 22nd about how a player with 500 alchemy and enchanting could create the lifebound alchemist stone and disenchant it into a Maelstrom Crystal. This was hotfixed in patch 4.0.3a which was released on live servers Tuesday January 18, 2011.
The beauty of this gold making method was that the cost of materials for the Lifebound Alchemist Stone was only around 800g whereas Maelstrom Crystals sold for around 2,500g (back on December 22nd), that is a profit of 1,700g for each maelstrom crystal you manage to sell.
Unfortunately I am late reporting this hotfix, the ideal situation would of been to buy out the AH of all the maelstrom crystal you could of, they were selling for 1900g on average before the fix and now they are going for 2800g!
Time to keep our eyes open for the next cheapest way to get our maelstrom crystals for those expensive enchants.
