[3.18] help fine tuning vaal lighnint strike build

hey, im following this guide: https://www.youtube.com/watch?v=kY3u4u1fMLA


and i reached a point where upgrading my gear costs too much that i can't afford it, but also despite managing to finish t16 (but the boss) i still feel like im struggling too much with mobs and surviving (spamming flasks like hell lol)

the build aims for ele dmg, crit mods and attack speed mostly and this is what i currently use:


(if theres a more compact and easy to understand way of showing stats please tell me)

any suggestions on how can i push this build a bit farther?
