This build ideal up to floor 500 . Ascendant and aftermath bonus robe with other things.
Then 400% Explosive hat.
Crushing blow and deadly strike. Add 30% weaken epic affix whenever you can as well as epic 5000 WD and 100% WD on Skyfall.
Haunting Amulet called Frightening Choker on it.
Also 4000% MH meteor ftw thanks to bonus and 40 hero point.
Magnify Talent, Focus (sorcery if fire or poison dot), Amplify (wizardry for easy elemental crit otherwise amplify with Ascendant ftw) and Empower (or Fester for dot like fire or poison).
Crushing flames if you can when you reach that floor or craft it using codex and full fire.
If you reached floor 400 or something, Aether Cover hat for 100% ED . Gauntlet with 200% WD from masochism axe from warrior jaspered to wizard .
Haunting good because it takes advantage of fear and you can get more Mh% damage with meteor. 4000%×2= 8000% if my interpretation of haunting is correct.
For other class, do whatever you think is best by Jaspered legends. No hero points though but to make up for that, Aftermath bonus and Haunting. Also possibly Elixir on weapon if you're that lucky and rich.
Sometimes you could try 2+ all sets on each weapon but it's great regardless.
