This will probably be my last solo COTA video before RoS. After a few suggestions from you guys, I crafted up a rare helm and switched to an Archon build for higher xp/hour. I clocked in at 1.65 billion. With a bit more damage and more focused play, I still think 2b is possible solo, but I'm not going to bore you with min/maxing. If I do another COTA video, it'll be aiming to break the 3 billion mark in group play.
