Encounter with KoC's first major foe

I didn't have 2x drop and I found the Rocky Mask Doll in less than 10 kills. None of the dolls ever took more than a handful of kills for me. I didn't think they were rare.

Yeah, I got most of them within 20-30 kills, I dunno what the pineapple happened here. Maybe it had something to do with the fact that I was doubling up on doing Winston's kill Mask quests at the same time? I dunno, I was kind of pissed off after 300 kills and nothing.
