Poison/Chaos Cracklance

So ever since the anomalous quality for Crackling Lance was released I wanted to try to make a poison Cracklance build. Never really worked out so far because there was no way (I knew of) to get quality high enough, however now with the new Dialla's Malefaction it might just work out. It probably won't be really good, I just want a version that works decent enough.

This obviously won't be a cheap build, but rather something I'd want to work towards later in the league (it needs Ashes of the Stars after all). But I was wondering if someone could take a look and give some thoughts on what could be improved. For example according to PoB Empower would actually be better than Enhance, it just feels bad not fully converting all damage. Also not sure about Arctic Armour vs. Tempest Shield.

But yeah basically the idea is to use Profane Bloom for clear and Crack Lance with a bit of cast speed to get Intensify up fast and deal good DoTs. I've also tried to go right side many times, but I honestly don't know how I would get any survivability in the shadow/witch area.
