Is there any way to improve my falling thunder/Whirlwind monk?

I'm using Blasphemy with Repulsion to generate power chargers, usually it's enough to do ' whirlwind with charged staff and then 1-2 falling thunders and reapeat

I use Elemental Conflux for lot of extra dmg, especially when it procs lighting it almost doubles my falling thunder damage. I don't use cast on critical anymore, I used it before but it's not worth the spirit investment

I one shot almost everything including pinnacle bosses but when I tried running 20 mods maps I died almost instantly. Not sure how would I improve my character more to be able to survive in those maps.

I have around 200 divines to spare maybe I could farm ritual for headhunter or mageblood but so far in two days of farming I didn't get anything
