It can sometimes be difficult to find the time to level-out a character. In Diablo 3, Youtuber Dat Modz went from Level 1 to Level 70 in just over a minute. And you could probably accomplish this even under a minute if you set yourself up correctly.
He enters the Nephalem Rift with a group of Level 70 players, by 1:06 he reached max level. The look on his face is priceless!
Do you think this is the fastest leveling method?
