Hardcore HC is an optional gaming mode in the Diablo series, implemented to give an extra level of challenge to players. If you choose to create and play a hardcore character, you do so at your own risk. Blizzard is not responsible for the death and loss of your hardcore characters for any reason including Internet lag, bugs, Acts of God, your little sister, or any other reason whatsoever. Consult the End User License Agreement for more details. Blizzard will not, and does not have the capability to restore any deceased Hardcore characters. Don't even ask.

Well since the original Diablo. I used to play hc on D2. Only a little on D3. I finally have a decent pc and, want to try more hc. Not much left in sc.
Why risk perma-death? Because Blizzard wants you to, and is prepared to reward you…. Games in which players are rewarded for their time with incentives — be it in the form of skills, in-game currency, equipment or new areas to investigate — usually allow them to keep their loot and progression even in the event of their character meeting a sticky end. The chances of this happening, incidentally, are pretty good.
