So i found this https://gracefuldusk.appspot.com/items/8185-Vortex-of-Souls while farming and i noticed it does native aether damage which is quite cool cause you have to skip the conversion thingy and can fully focus on aether+another element you might like.
My idea was something like that : http://grimcalc.com/build/lZGRnm
Cause aether does good with fire. Another option could be druid with lightning dmg and primal strike.
Gear wise iksandra set would be a great option and there are lot of epics/legendaries giving+ ather+ elemental. for devotions i would ofc take the kraken, was considering the widow to lower their res a lil bit and ofc all the usual life+ res stuff.
I would like some suggestions.
