PoE SensitiveTrap builds

POB: I followed maxroll.gg guide for it but I think i pretty much covered all the basis, the only thing that I was thinking I could improve was +2 neck and better jewels, can someone offer other upgrades I may be missing? First time with MB so not sure what flask setup I should use

I am wondering what can I get to improve my defenses, I just feel like I get 1 tap on every mob. Other improvements are welcomed!
