The fucked up thing is that I didn't originally start this run going for naneinf, but since I stumbled into it I'm like, "fuck it, we ball". I was trying to finish out my joker collection, just needed Eris unlocked for the Astronomer joker, which I saw in the shop literally just before I hit "next round". So not only did I fail the naneinf, I failed at completing my joker collection too.
For real lol, run absolutely murdered
