From my first win on UV through Ossuary route, I noticed that two ranks of Eagle Eye boost shotguns well, so an idea was born how to tackle Diamond badge for Angel of Shotgunnery challenge, which demands you to win N! without taking a mastery.
Key decisions:
1) armor replaced twice: ablative -> combat -> infiltration. (Didn't care about loss of dodge)
2) Second Chamber rerolled into Critical 40 at Tyre Outpost. Actually was supposed to rerolling on another gun (auto-shotgun), accidentally rerolled on main shotgun. But Critical 40 proved to achieve kills in one hit, meaning I didn't miss Second Chamber in practice.
3) snatching that poison immunity in Rift (and thus also be able to upgrade it in Mephitic Mines) - I think I got Filtered helm to go at this, otherwise too low chance to succeed at claiming that one to bother attempt it.
4) heading for exit elevators in Dante, only killing encountered/aggroed enemies, but avoiding drawing more opposition, and sometimes using stealth ability to reach the exit (but make sure that elevators aren't blocked, including by some exalt spawning with a specific elevator-blocking trait - just one of these could ruin this entire run)
I am a stranger to Nightmare difficulty, so luck factor was great in my victory, and I also burned three military stims and a couple of phase kits at the final boss. So somewhere the build power wasn't apparently enough (then again, where is my relic? didn't get any good one).
