I've been working on this one for awhile - the early game's a giant pain in the ass. Once the build gets rolling, though, it gets pretty easy - Intuition->Cateye makes it safe and simple to snipe(or blast) enemies before they can get in range, multiple levels of HR and Finesse reduce time passage significantly, and those Phase Boots and an ample supply of A modkits didn't hurt. The only real issue was Ammo - I started dropping medkits as I realized I wasn't really using them, and collecting large quantities of Energy Cells on the levels where I found them, so that issue went away. Managed to find invulnerability on Hell 7, so damageless Mastermind was trivial, since my damage output with HP Plasma Rifle and AoMC was more then enough to finish her before the duration lapsed.
Not sure how doable this badge would be without the AoMC pairing allowed by the Dual Angel challenge mode. Max Carnage synergizes well with the safety of the build, and the extra accuracy and damage is paramount to clearing levels in time. Quartermaster Angelic, requiring AAoRA and so disallowing Dual Angel mode, as well as more then halving the time limit(even with the lower kill percentage requirement), is probably not realistically possible - but then that seems to be true of many Angelic challenges.
