Mob engineering, or Salvaging, can be done by engineers on some (mostly mechanical) corpses after they have been looted. The mechanism is similar to skinning, but gives engineering parts rather than leathers.
Eligible mobs
Only mechanical mobs can be salvaged. Most are found in Northrend, though Harvest Watchers in Westfall are an early exception.
Drops
There are three types of loot that can be obtained through salvage: Junk, Reagents, and Special drops.
