Tier 3 cursed had a Mr peeks spawn on round 4 and got damn near every perk eternal, both WWs, war machine, kazimir, pack 3 crystal and gold wrench.
Plus I had samathas drawing equipped and multi-pack augment on so every round had a chance to immediately pap one of my 4 weapons to tier III and only had to purchase tier IV once bc it did the same thing (bug or intended?) either way, amazing run. Got the spider fang relic this game too
