re: the loot, I've only got the HE Aug and Super 90 from him. Then again, I only farmed for 45 mins. I think all the weapon parts he dropped were mags.
Got Yesterday HE AUG- 21,50% Crit Chance 10,2k dmg, Deadly, Responsive and Unforgiving talent. Pretty good! Still no better than my Vector but well- it will be nice to equip something else
Glad I got it before todays Patch which fixed boss farming from outside of mission area
RIP boss farm!
As of todays update this no longer works.
It's been fixed I think, boss only drop at first round.
