Engineering leveling guide
Engineering in MoP Classic runs from 525 to 600 on 
Ghost Iron Bar, turned into 
Ghost Iron Bolts and 
High-Explosive Gunpowder, which makes Mining the natural partner. The route needs about 180 bolts and 30 gunpowder in total. Counts are approximate: a recipe can turn green a few points earlier or later.

Trainers and tips
- Zen Master Engineering is taught by the engineering trainers in the capital cities from character level 80, so you do not have to travel to Pandaria for it.
- Make bolts and gunpowder as you go: making them all at 525 wastes nothing, because they stay useful to the end.
Lord Blastington’s Scope of Doom (Ghost Iron Bolts, 
Primordial Ruby and a Spirit of Harmony) works as well as Mist-Piercing Goggles for the last points.
