i forgot what is the cataclysm ring. is it the mayhem ring which consist of lots of procs?
discordance build. der lots of ways to use this build one is to make a build that inc ur special skill mh dmg by adding multi attack affix as well as being able to spam it well
another is u can spam ur mh special skill infinitely (if u have mana) ex. blinkstrike special skill w/torrent or earthshatter or smokebomb proc then u rely on procs for dmg/dps. it depends on u what u prefer on how u set it up.
as for element i highly suggest u use. ice then add frozen affix really OP helps ur burst mob/carto in mere sec. can clear pack size mob easily. another choice is arcanist + ascendant affix this is pretty OP this 2.3 u can inc ur dmg significantly by arcanist arcane debuff (dont use ignore resist affix on this build. use weaken % affix pump it up 150-200%) for better dmg boost
