Where Infernal Blow burns hot, Glacial Hammer freezes to the bone. The spell infuses a Mace or Staff with the essence of pure ice, making a weapon so cold it can barely be handled. A successful hit from Glacial Hammer deals grievous damage, and if the target is already frozen and near death, it will shatter into thousands of shards. The more skilled one becomes at inscribing the runes for Glacial Hammer, the greater the frostbite becomes, eventually leaving most foes frozen solid.Description on the official Path of Exile website
