Once upon a time in 1.09 I had a barbarian named Me_Break_Skull, who used a Shael-ed Messerschmidts Reaver to whirl-tirl-you-hurl. We were doing Hell-Baalruns for the fun of it (it not being the XP cow it is now), and on the 7th or 8th run we ran into ESFELE Listor. So I hurl (l77, 3500 hp, max res)... and I get hit a few times, am down to 75% health. I move into a new position, get smacked by Listor, and die. I die? WTF? I die! Well, that happens from time to time, so I'm not impressed... and besides, characters in Hell... I had like two dozen Hell-chars at that time, all equipped with a good selection of gear. Oh, and since I was playing with friends they could loot me...
"So, uh, you didn't set loot then?"
"Yes I did!..."
"No you didn't."
three seconds pass
"Ah, well, damn, waste of a nice 15% res all 6% LL ring then. Shame... I liked that ring..."
...and I grab my Thrower/Zerk Hybrid I had been using since forever and keep on playing. Probably one of the best rings I ever had... down the drain in a second because I forgot to set loot with friends. Never forgot to set loot again.
