Does Acrobatics/Phase Acrobatics worth

Hello ,

I am trying to build witch incinerateor in Tempest league(still dont use incinerate ,just leveling the gem and waiting for good 4/5 link to equip).

Soo i just added one point at Acrobatics and i think to add in Phase Acrobatics too im 52 level ,but i am starting to doubt is that worth enough.

The thing i worry about is that ES and armor reduction( at this point i prioritize HP and resists and dont care about armor ) .

So my point is :

Is there a minimum ES/Armor you should have before adding that skill point , i really need help because i will go to merciless soon and i dont want to die again :D

My character name is PAIAK you can check my current gear too.

P.S (sorry for my not perfect english)

Thanks for the answer ,so i shoud wait untill level 60 and buy Light Coil before i add points in Acrobatics and Pahse Acrobatics ,or its better to have that aditional spell block and take more phys dmg (already runing Arctic armor)

I have somewhat progressed your tree with things you should do to make this work. I suggest you go evasion/energy shield combined type of defense and take more HP as I have done.
Whether this is playable is hard to say - to some extent certainly.
