Blade Vortex Build Upgrade HELP

Hi,
I've built up a blade vortex based Trickster, using Blade Vortex, added Chaos, Void Manipulation, Poison & Increased AoE/Faster Casting (Switching last two for clear vs boss fight) in my 5 link. I can get 19 blades going for 10k avg damage (about half chaos/physical)



These are the key items I'm working with atm, but am wondering if there's anything higher tier than these I should switch to, or any recommendations for what to get for the rest of my set (atm I am running the rest with defensive rares, mostly ES based). Also, I haven't gone crit-based so far.

I'm pretty new to the game, so any help is great. I also just started getting some decent currency, so am not too worried if something is on the expensive side (wouldn't mine spending a few ex if there was a top tier weapon/armour upgrade)

Thanks!
