Finally got the Mad Warrior leggings using the 'console quit trick'! A big thanks to all who chimed in with any info/advice.
Now, before you go, an important PSA regarding the 'console quit trick':
Firstly, it works like a charm, so don't worry about that. What you do need to know, however, is that any item that you pick up does NOT stay in your inventory if you do the CQT again immediately after (required) i.e. go to the dash without the game triggering another save, which is what the CQT is, basically. I stupidly thought - for whatever reason - that the items would remain and that I had been racking up dupes the whole time, so when I finally got my leggings, I figured I'd do a few more rounds for the heck of it. Big mistake; back to square one.
Luckily, all that was lost was an ascetic and another half an hour or so, but yeah, it was annoying.
All is well and good now, though. It's a great looking set. Not so sold on the mask, as it's a bit too on the nose with the Predator homage, but it goes nicely with a lot of other helms.
One last question: is there any reason why the CQT wouldn't work with the Aurous fellow? It seems a lot easier than the 'fog trick'.
