POBS: https://pobb.in/2zH3qoobmToG - early-midgame build with some progression
https://pobb.in/njoBE7ditB6M - lategame about 90div build.
I tried to keep those pob relatively conservative, even turning all my flasks down, hope i havent padded anything.

There was a pretty similar build to this one yesterday, but on a scion base, while they are both quite similar, i'm not sure one of them is better or worse.

In this build we utilize rathpit + dissolution of the flesh interaction to gain "free" 300+ inc. crit and spell damage and pairing it with huge flad dmg on hexblast, we are also using double curse setup to automate curses so we can benefit from 100% more hit damage on hexblast skill gem.
Running around with 1 hp but still packing a pretty decent amount of life feels weird at first, but you will get used to it pretty fast.
All in all this build is super fun, really powerful and relatively easy and cheap to put together.
If you have any questions about it lmk in the comments here and i'll try to explain stuff.
