As many of you know, the Ascended Calibur and the Leviathan Blade are both better in every way to the Cold Iron Carver and the Cold Iron Vanquisher except for having a damage bonus to the undead family of high. Even though it has that damage bonus, it is still highly unpopular because of having better swords for the job so it would be quite unlikely to be seeing one of those. Also, having the Leviathan blade line recipes free from doing missions, it makes this sword seem useless.
An idea that i have thought of is having both the Cold Iron Carver and Vanquisher having a slight chance of causing strong freeze so it can even it out with the Ascended Calibur and the Leviathan Blade also the Cold Iron line looks ice themed already so no major (if any) cosmetics is needed to make it look like it has the freeze status to it.
Please leave any comments, suggestions and constructive criticism.
Being an adamant believer of the Vanquisher and his teachings, I'd say that freeze wouldn't exactly be the best choice seeing as a simple blizzbrand can beat it damage-wise. (Having a CIV undead medium + radiant silvermail is weaker than a Blizzbrand + radiant silvermail by 20-30 points of DMG) But I agree, having it buffed would help.
