CI Occu Winter Orb CwC Vortex

So, I am fairly new to theorycrafting and I have never played a ES build let alone CI. I thought I should give it a try but the problem is I never played a caster either. The closest thing to a caster would be a trapper so yeah.

I stacked all the es I could find in the witch area. Gone for some cold damage nodes to boost the deeps. According to PoB I sit at 10k ES and I wonder if it is enough to stay alive with not so cheap gear equipped.

Of course we don't know how Winter Orb will actually perform but by the looks of it it doesn't look to shabby.



Any help would be greatly appreciated and if it straight up trash then let me know it.
