Stockpile Mats Now

When Cataclysm hits there will be a huge influx of new toons on most realms, many of them with BoA gear equipped. An Enchanter that prepares for this in advance will stand to make significant gold in the first few months of the new expansion. Due to the limited number of useful enchants that can applied to the BoA gear, it's a simple thing to do. Below are the enchanting scrolls most likely to be in high demand.


Enchants:
Scroll of Enchant Weapon - Crusader
Scroll of Enchant Weapon - Fiery Weapon
Scroll of Enchant Weapon - Agility
Scroll of Enchant Chest - Greater Stats


Mats Required:
Large Brilliant Shard
Righteous Orb
Small Radiant Shard
Essence of Air
Essence of Fire
Illusion Dust

There are other enchants that work for BoA gear as well, but these will be the biggest sellers. More sophisticated enchanters can look up the rest and try to get the mats for those as well. If you decide to do nothing else, just add these items to your Snatch list in Auctioneer and grab them anytime they're selling at a reasonable price. Either turn them into the scrolls above or just hold them until Cata and sell them at a huge profit as demand will skyrocket.
