I honestly don’t know and I doubt somebody does. As a I said, Shards 75-76 are very random, it can be a breeze or it can be an impenetrable wall on some boss chunks with some mutators, so it’s hard to quantify. I guess one of the very top builds for it would my Dark One Conjurer. It will never have any problems at Shards 75-76 or Crucible 150-170.
