PoE BoyThatCries builds

I posted about transitioning from LA to TS not too long ago. I managed to farm enough currency for the Volls/Kaoms/Hyrri's Ire version. My bow has 1k ele dps on a spine base. My crit chance does not go above 50%. I'm not sure if i need higher crit chance on my rings? Or am I just looking for multiplier? I've seen a few builds on poeninja with 100% crit chance but I cannot seem to find where it's coming from. &x200B; Also haven't updated my passive tree in a little while so hoping someone can find any holes i've left there.
