Ahh the many, many, many,many memories of Diablo 2.
I could name so many of them, since I was a pretty good dueler on Hardcore Classic.
I thought the funniest and the most easiest duel was this one....
Well I was in the usual Diablo 2 classic channel, and this 83 Hybrid xpac zon comes into the channel and ask's anyone for a loot duel, no one responds within a couple minutes, so I'm thinking, what the hell, why not?! So I tell the amazon i'll duel him, grab my barb(lvl 85 with ith,valor,arreats,ss and other shit.) Anyhow I tell him the privite game, he brings his 89 zon friend to loot him(So i guess it wasn't a loot duel) and I didn't have anyone to loot me, so I was thinking, "eh, its just a game..." So he hostiles me and runs out(while in javazon mode) and he runs by this house and tries to hit "w" which is the weapon switch, but keep in mind, my barbs extremely fast (maxed run speed) and I simply run out, whirlwind twice, and it kills the 83 zon. Ear + Money.
After he died he goes "WTF, how did you kill me?" And his friend then tried to hostile me and shoot from the bridge, So i ran around his arrows and ww'd him, he chickened and exited, his friend lost his loot, and his friend almost died too, would of been a nice duel. an 83/89 zon ear

.
Hmm, let me think of another one.
Oh, this one time when I had my Sword/sheild dueler on hardcore classic I was in a barb V barb game and this kid comes in(Nis nickname was RHCP, for most of you people, that means RedHotChillipeppers) anyhow, he comes in with his lancer, and since I was an upcoming dueler in the Hardcore classic thing, he thought I would be easy. Anyhow, we start dueling, and I didn't get him to half life at all, but then he tried to lure me into a corner, where he thought he had the advantage, but I saw it and counter-ww'd him before he could do it, and ww'd back over him, killing him and then his chicken kicked in.
Ahhh, good times.
