Oh yeah, I did the unicorn quest already at that point, haha. I was really messing around a lot after clearing the Air and Stone Temples with no planning beforehand, basically just walking in and killing the bosses while their posse helplessly pecked at me. So I ran to smith random things, and spent long enough under level 30-40 to use up all the scrolls of chaos resistance I got from that mystic in Dwarftown. That's when I did the unicorn quest. I'd still have had a chance to remove a corruption or two, but when I got the "lighter" corruption (which made wearing the greater moloch's armor impossible), I was right in the middle of a greater vault. I didn't make it out half-naked. Next time, I'll be serious about it.
