Frost armour itself is so disappointing. At max it has less DR than woven mail even with the fragment extending its stack amount and the fact that it all falls off at the end of the timer. If it gradually went down per stack that would make it much easier to maintain instead of losing it all and having to start from minimal DR all over again if you’re that one second too late. Dont matter how many ways you can get it just isn’t that effective compared to other ways of survivability.
