I have found a way to make some sweet gold with engineering ;p
First we will be working with selling Electrified Ethers. This can be server dependent depending if someone is already selling them.
1. Buy Volatile airs *30g a piece on my server*
2.Make electrified Ethers
3. Check the AH for the current price, if none then list them for 200-250g
4. Profit $$
