I can make infinity and I play Frozen orb sorc. I got sunder charm (Expansion one, not the ROWT latent one) and I got 2 Bers.

With cold mastery being -190% and Sunder breaiking - will infinity even do anything?

edit - i also got 3 5/5 cold facets, - but -200% is the max - thats what shown on the stats page.

-res from cold mastery works at a reduced rate vs broken immunes. infinity would increase dmg substantially vs those

But it's already at 200% though - so, technically, no further reduction is even possible.

Sunder breaks it.
Then Cold Mastery nukes the rest, no?

what do you think works at a reduced rate means

I dont understand the question.
Can it work past 200 already reduced?
Does it make sense to use Infinity?

I don't understand the whole "works at a reduced rate" - what does it mean? I've read that with resistances -200 (aka goign to -100 on a mob) it cant go past that. Frost mastery is unique in comparison to Light or Fire.

conv aura and cold mastery work multiplied by 1/5... (only for sundered cold immunes)

so ur -200 is actually -40 after sunder
infy will give another -17

so without any other facets -> 95 (after sunder) - 57 -> still 38 coldres


edit:

to go fruther: 17 / 45 = 0,377 -> close to 38% more dmg with infy vs cold immunes than without

I’d recommend maxing both blizz and orb (and all their synergies), putting only 1 pt in cold mastery (up to like 4-5 pts at lvl 99), and rely more on -res from gear.

-res from gear is fully effective against broken immunities, but conv and CM are only 1/5

Doom -60
Sunder -10
Protector in NW -10
Facet in viper -5
4x facets in monarch -20

That’s 105 flat pen from gear

With 1 hard point in CM, all non-immunes are already down to -100

Sundered mob is set to 95res
95-105= -10
Then CM gives you only -1% per lvl
And infinity -17%

And if you don’t play on p8, that extra 17% pen you get from infinity only vs immunes is not worth it over the QoL of insight (not only for mana but also for the triple heal aura)

Blizz + Orb is great cuz they don’t share the same delay like they used to.
You get a lot of dmg when you cast both in alternance.
Orb is also great at clearing low player count and/or high density of squishy mobs like flayers.

You still get to 105% fcr with the gear I listed above.
Viper 30%
Arach 20%
Trang 20%
2x fcr rings (could be opalvein cold)
15fcr amy

Or you can make it cheaper and replace those rings and amy by a 35% fcr spirit mon, using sojs/mara instead. Cheaper, better defensively, just a bit less dmg.
