I could use some help improving my Forbidden Rite Trickster

I decided to reroll my trickster to Forbidden Rite of Soul Sacrifice and kind of just threw together a couple different ideas from poe.ninja and Palsteron's guide.

Ideally I want to get MB, drop purity of elements, add another offensive aura, and maybe get some awakened gems but beyond that I really don't know what I'm doing to improve the build.

I'm currently sitting on 100~ div and hoping someone can offer some advice on what to focus on next.
