Over 65000 strength? K perhbaps not stat hacking, but obviously cloning the bears, no-one can accumulate THAT many bears.
I have all characters max level'd, although my Barb would be the strongest. He one shots the final boss on good, with a 40 k crit. That's using Anccestral Call, Slam, then the Critical Hit circle. I have not stat hacked or cloned anything, it ruins the game IMO =)
