so while we were doing an alt run, somehow gamon and all the trash we skipped got pulled into the room and doomlord and nazgrim fought for like 5 minutes - not doing any damage to eachother though. i started the stream after we had been dead for about a minute already just sitting there. after berserking nazgrim and doomlord still werent doing anything to eachother lol. apparently 30s into a berserk though bosses just despawn.
