 * The Art of Fel Reaver Maintenance
 * The Doctor's Key

Description
The best way to destroy the rest of the Legion's supplies is to use their own weapons against them. I've been working on a rig that will let you take control of one of those Fel Reaver Sentinels below.

There are a couple things I need to work out, yet. For that, I'll need the manual that Doctor Maleficus keeps locked in a chest near the bottom of the ramp. He probably won't give up the key without a fight, so you'll need to capture it. Bring the fel reaver manual back to me and I'll do the rest.

Progression
Did you get that manual?

Completion
This has the information I'm looking for. Just a couple more tweaks, and we'll have you taking control of a fel reaver in no time.

Gains
Upon completion of this quest you will gain:
 * 12300 experience (or at level 70)
