For the campaign - they’re good. I haven’t tested them in SR or Crucible. Not sure, if I would attempt to kill any Celestials with them, but here you go:
1] Acid Witch Hunter - DW ranged - Witch Hunter, Level 100 (GD 1.2.1.2) - Grim Dawn Build Calculator
2] Acid Witch Hunter - 2H ranged - Witch Hunter, Level 100 (GD 1.2.1.2) - Grim Dawn Build Calculator
And to be honest - many ranged builds are missing in the Compendiums, because they don’t match up the standards of “killing everything you look at”.
