Condemn Akkhan was the KING of Season 1 back in august 2014 - march 2015. The very first season in Diablo 3. I've been trying to bring Condemn up-to-date and make it viable and came up with this build after a lot of experiments. One of the most elusive builds in my opinion!
Oldschool Akkhan version of Condemn is, unfortunately, not viable at the moment because of very low toughness. You simply won't survive in GR70+ at all.
