Assassin/Ninja Help Tfa? Cata Help

Hi, I am using a TFA build for my cata
https://wynnbuilder.github.io/index.html#4_0K90mM0aN0Ju09q09q0ON0og0QQ-Y2C+m1K0v1g000010036C
(It is negitive 6840 sadly)

I was wondering if there is anyway to improve my damage, with this build without Sacrificing too much ehp. This is for 1.20.3 , I can't afford mythic boots, but I am fine with LI, also I am fine with any elemental combo, as long as it has a decent EHP and great damage.
