I don't always do that much math, but in the case of getting freeze chance sky-high and perma freezing, it makes sense to calculate cast speed, freeze duration, etc.
Everyone tries their hand at the coldsnap perma freeze build at one point or another. Sometimes it works. My attempt was nearly a year ago now, before Romira's, and it didn't. I haven't revisited the concept yet...actually IDEA. What ever did happen to coldsnap trapping? It'll probably work. I hope it will.
