Hello builders,

I've made (carbon copied) a zhp zdps tota cheese build and it's going fine but there's some road ahead of me to rank 2000 and I decided it would be nice to make it more comfy and I'd be glad to hear your ideas. Here's my POB: https://pobb.in/0qxEC-t_FPM8

Here are my ideas / questions / concerns:

1. in POB I have 95% evade chance, but in game character stats sheet says I have 90%, I should assume POB is correct, I hit cap and there's no reason to increase evasion?
2. I have 69% spell block chance so I guess there's still 6% to get, how could I go about it without losing other stuff?
3. Would "increased AOE range per quality" harvest enchant increase range of both Void Sphere and Storm Brand? I think it should and it's a no-brainer but I don't see it on most Poe.ninja builds.
4. POB i copied has Hinekora Makanga tats (increased curse effect) paired with Warrior's Tale, I haven't put the tats on yet but I probably will, is there a better alternative?
5. I suppose it'd be worth getting more chance/effect of chills, freezes, knockbacks, hinders etc., how to do it well and again, without losing other stuff? Tasalio Shaman tat (5% chance to hinder on spell hit) would probably be good? Tukohama Brawler tat (10% chance to knock back on hit) could probably work too, but I don't have any small strength nodes specced or nearby. What else?
6. I have a free jewel slot, what would be good there? One thing could be Impossible Escape to spec some strength nodes to put Tukohama Brawler or other strength tattoos.
7. I think (need to check) I could fit another flask if I use some "increased flask duration" tattoos (I rely on 100% flask uptime with The Traitor keystone (4 charges every 5 sec per empty flask slot), anything useful I could get there? I already have Onslaught and Phasing because Raider ^^
8. Anything else I'm missing?

Let's say I'm comfortable with spending up to 15-20 div, could be lower, could be higher if there would be some crazy good benefit.
