First time I was a bit over 100 hours in at the second to last boss. However, I wasted a lot of time exploring and grinding in my first game. I was like level 100 at the second to last boss.
On my second playthrough, I knew how to use combat system perfectly in all situations, and had a much easier time going through the game. Plus I knew where everything was. That time, I think I beat it at level 86 in around 40-50 hours. With lots of help from friends via co-op, of course.
