For some perspective, at 6.0 bonus multiplier, to get enough wisdom to be a wizard it would mean playing this game for about 10^20 years. As a reference, the universe is only about 10^10 years old, so the rough scale difference between the amount of time it took you to read this comment and the age of the universe is about the difference between the age of the universe and the amount of time it would take to become a wizard. No wonder there aren't any wizards.
