Engineering vendor

This is a guide to finding and utilizing the Engineering Suppliers scattered throughout Azeroth. In many cases these vendor NPCs can sell you those quest and material Engineering items that would otherwise take you a few hours to grind. It's not a bad idea to make the rounds and stock up on a few of these supplies just in case. Prolific materials, such as Rough and Coarse Blasting Powders, are omitted in favor of the more esoteric necessities.
