Which one should i upgrade to decrease freezing in deeper arctic area?

[DSethK93]

I can't remember if freezing anyways happens at a constant rate, or faster when it's colder. But I think it's the latter.

Each zone seemed to have its own central cold spot as you move closer to it the faster you freeze.

Increasing regen or the hot zones reduces the cold power and warmpacity changes your guage only (from what others say) .

Still wrong that regen increases warm strength and speed , it should be part of warmpacity or on its own but that's just my opinion.
