Below is a detailed walk-through on how to level Engineering 1-525 quickly and easily. This guide is as complete as I can make it but players may have to purchase extra Engineering materials due to sometimes not getting a point from a yellowed item. Some players may also find that making different items are cheaper on their server depending on their economy. In total, expect to spend 7,200-7,700g leveling Engineering. (Note: You should be able to recover around 3,200g or more by selling items on the Auction House or disenchanting them depending on your server's economy). Please enjoy this Engineering 1-525 Guide and if you have any questions or feedback feel free to post them on our forums.
