PoE Occultist, League Starter, Bow builds

I ran this build as my league starter in 3.17 when ashes was easy to get, I loved the clear speed I got from this as well as how tanky it felt vs bosses so I farmed a lot of uber elders with it, not really invincible but with divine flesh and few phys damage reduction sources not much could one shot it at that time. I kinda wanna do the same build for my second or third build for this league with new Vaal Caustic arrow but not sure how meta has changed and what is new, skipped most of Sentinel and Kaladnra leagues. I could not find all the gear pieces that i used but missing ones were nothing

Current latest updated pob: (Thanks to bodelotte for the suggestions/improvements!) Above is what I have so far. I love storm rain, but it's not ideal for me for mapping. With the new Voltaxic Rift 100% lightning -> chaos conversion, occultist becomes interesting. This means profane bloom could help solve some of the mapping issues for me. I have never made a build however, most of the times I just follow someone elses guide and change it a bit. I thought maybe
