Boneshatter - a bit of help needed

Hello everyone!
I played PoE something like 7 years ago and since then forgot almost everything.
After returning decided to try boneshatter build and now a bit struggling what to do next. What could I do for making it stronger? What jewels to add or what passives to replace? https://pobb.in/xY6qbO267yLb
Thanks everybody for any advice!
