Mechanical Repair Kit is used to restore 700 health to a friendly mechanical target. Use this in emergencies or after you've had a huge fight.
Mechanical Repair Kit is created by an engineer with a skill of 200. The schematic is learned from a trainer.
Mechanical Repair Kit as a quest objective
A Mechanical Repair Kit has only one charge. You can use it once, and then it's gone. If you intend to repair a lot, bring multiple kits. They stack in lots of five.
While there exist some mechanical targets you might wish to repair, there are not many. Note that of the ones below, the Battle Chicken lasts the longest (90 seconds).
- Compact Harvest Reaper (pet)
- Mechanical Dragonling
- Gnomish Battle Chicken
- Target Dummy
- Advanced Target Dummy
- Masterwork Target Dummy
If holding a PvP objective is important, like the main keep in Wintergrasp, Mechanical Repair Kits will also heal vehicles and turrets for approximately 2k health. A small team of engineers could theoretically top off turrets in the main keep after unsuccessful assaults. These do not, however, appear to heal walls.
