I farmed this guy with a level 30 for a day and received the following items:
100,000 Credits worth of Blues and Greens
6 Purple items that sold for defult price on the GTN
6 Crafting Schematics (Armormech and Synthweaving)
Battle Expulsor's Armguards x2
Omenbringer's Bracers x2
Omenbringer's Waistwrap
TD-17A Talon Bracers
RD-07A Spider Bracers
He is a veritable loot pinata; ready to be wacked open and then exploading with loot!
Randomly drops orange bracers for all Republic classes via the quest Enemies of the Republic.
If you wish to farm the bracers (high level toon recommended) you can reset this mission repeatedly. Just run outside the entrance and click "reset". Don't panic if it is greyed out ... you can only reset once every 2 minutes and a L50 will not have any problem getting in and killing this boss in under 2 minutes.
Some people will get lucky and see a bracer on their first, third or 6th drop ... and post happy comments here. I'll let you know it took me 29 kills to get any bracers (and I was farming Consular bracers, not the Trooper bracers I got ... money isn't the issue so much as none of the kind I need are available). Since you can kill it around 30 times an hour, this isn't sooooo bad. Then again, it is quite possible the one you need may NEVER drop for you.
