Diablo 4 "Mortal" Frozen Orb Sorc is fine in Season 4.... (copium) *pre mid-season pit nerf*

After hearing news about the upcoming midseason balance patch, I decided to try frozen orb build without any flame shield uptime shenanigans thinking that the immortal tech might get deleted. But I was wrong.
Anyway, I had a blast playing with a Sorc build that doesn't rely on flame shield. It is just as good at speedrunning lower tier pit (tiers 70-90 depending on gear) and can push to tier 100, which I did manage to do once. But the issue with pushing higher is that TTK becomes higher and higher to a point where you can't kill elites within the CC duration and at that point you might as well switch to a better build/class.
The version in the video uses 5 uniques (shako, tibault's will, esu's heirloom, fractured winterglass, tal rasha's). I tried to run starless skies as well but dropped it when I realized that it was hurting ice armor uptime due to skill cost reduction + no attack speed affix. But otherwise, it is a good option too.
If you want to try a build that uses as many uniques as possible, this one is rock solid. You can also add a soulbrand/raimant just to achieve that goal :)
EDIT: Post mid-season pit nerfs, this build can easily farm tier 100s and push a lot further.

So much button pressing to get the same results as 1 barb bash atk lol. blizzard is a joke of a company.

Atleast they didn't "buff" sorc this time and break stuff like other things in the patch. Good job blizzard I guess...

"MORTAL" but PIT 80, this is a joke?

[@sprayroyale3918]

Well, any sorc without permanent uptime on flame shield is a joke rn. FO is atleast the best among the rest. FYI it can easily farm tier 100 post mid-season update. Certainly cannot push as far as immortal variants but that's not the goal here.
