frost crunch and blizzard works off PoisonResistanceRate=0
which is PR....
i forget which way it goes now... but if u set it to like 50... things like moths para 1/1, blizz/fc works all time... etc etc
when its at 0 it hardly/dont work, same with moths etc
think on OS i have it set to about 9 or 10 if that helps
freeze/psn only affect slow/PA
