Improve my build - Where should i start? whats next? Spiritwalker Twister

hey peeps

i'm struggling with my twister spiritwalker, following these two guides:

guythatdies: https://mobalytics.gg/poe-2/builds/spirit-walker-twisters-guythatdies

siahz: https://mobalytics.gg/poe-2/profile/siahz/builds/siahz-s-spirit-walker-twister

my current build looks like this: https://maxroll.gg/poe2/pob/mo9n3m0y

ofcourse my two main issues are damage and survivability.

the siahz build (i'm currently mostly following equipment wise) is more affordable but makes me (i think at least so) very squishy. the guythatdies crit build is super high end and i cannot for the live of me generate that currency.

where would you start? what would you do? i have ~3 div to start the change.

appreciate the help and thank you
