A dedicated barbarian has recorded the first hardcore inferno completion of Diablo III, achieving the feat in little more than one month.

Kripparrian, from Toronto, Canada, managed to beat all four of Diablo III's difficulty settings using a hardcore Barbarian - aided by a Wizard called Krippi.

Not only is Inferno super difficult, but using a hardcore character meant that the barbarian would have been lost forever if killed.

The achievement has also been confirmed by Blizzard community manager Bashiok.

"My apologies Kripp and Krippi, looks like you were 1st HC Inferno clear," he tweeted. "(my spreadsheet deciphering isn't what it used to be) Congrats!"
