Would appreciate a consultation

HELLO EVERYONE

So , to make it short , I copied Fubgun's KB wander build ..
this is my build : https://pobb.in/1KlqPiz25Ijg
And this is the build I copied : https://pobb.in/N-FtA_1xROLb

Would appreciate if some one can guide me on what part of the gear I can upgrade now ??
Maybe my rare ring get a mirrored perfect rolled one for 1 mirror ?
replace the helm with a rare mirrored one with abyss socket ??

This build is soo fun , this is the first time I do a build that costed me more than 2-3 mirrors ..
