Hexblast Sabo with Rathpith and Dissolution of the Flesh?

Hello there !

I'm trying to create an Hexblast Sabo with Rathpith and Dissolution of the flesh.

Got some damage but it's seem i miss something.
Oh and it's hard to use zealotry with Divine Blessing.

I'm trying to guess what to do by looking at people on PoE Ninja but some build are Insanely expensive (mageblood etc...)



So if some expert can tell me what to do, if i need to pump a lot more of divine in it and if it's worth it it'll help me a lot !


There is my character :
