LESSSSSSGGGGGGOOOOOO!!!!!!
Me and my friend had like 5-10 minutes before we had to call it for the night when we entered the spawn area, and he joked we should go to Vegas if I actually got it. I was mainly doing the fights too, I hadn't gotten the instakill tactic fully down yet, and got it at the end of one. I'm stoked I don't have to spend potentially an hour and a half getting that thing.
You can look up "gutsy bat is free" by Aurilliux for a relatively doable RNG manip.
It depends on character name length though.
