You dont really need to max cold mastery for pvm
The most ull need is to have -200 pierce
Icebolt.
/infinity will never truly break a cold immune in hell that matters, so a monster with 99 res will require 199 pierce to go to -100 and cm goes in increments of 5
Whether or not monster cold res can actually vary between 95 and 100 though i dont know. Most ud waste is 1 skill point
