Level 93 SRS Necromancer needs help

Hi I am kind of new to POE since I joined at the end of 3.13, and this league my character is the Zizaran SRS Necromancer.
At level 93 6k life I find my damage and clear speed to be very lacking.
My gear needs improvement but I'm not sure how to go about crafting and the recommended gear on trade either cost many exalts or is not to be found.
I have 100 chaos at the moment after a few days of playing.

Could you please look at my character and give some advice on what the best next upgrade would be?

Thanks !

Hey,

I'm playing the same build currently. The clear speed in general feels not that good, but it seems that is a disadvantage of the build. I'd recommend to use "infernal legion" when mapping and switch to another gem when dealing with tougher enemies (bosses). It makes quite a difference, as the SRS pop way faster, therefore increasing the clear speed.

Next, try to get a Tavukai Amulet with negative chaos resist, it also makes quite a difference, as the SRS pops even faster. Try to get -15 or whatever.

Now I gotta go, maybe I take another look later :)
