I always think of grind when I think of Diablo... I recall spending endless hours leveling an Amazon and her amazon merc to 99 in Diablo II where it took days of the cows just to gain a level whilst being at constant risk of losing days of work from one death.
Bleh. I was really into stacking up tons of MF at the time and there was this thing called the "Ward Bow" I believe that was ridiculously good. I also recall some barbs using ist runes in two six-slotted swords, but I believe the Ward Bow still added up to more.
Fun times. Wasted a lot of my youth there.
