I just watched a very impressive Diablo Summer Games Done Quick 2016 run by Funkmastermp where he blows through the game in 20 minutes. This is pretty impressive considering the very slow character run speed in the original Diablo and that Funmastermp never gets his character over level 3. Funkmastermp uses a frame timed item dupe to get a ton of gold to buy enough mana potions and items. At one point he needs to get a teleport scroll tome and has to talk to reload the game and talk to Adria over 50 times.

This is a really good run and if you are a fan of Diablo something you should watch.
