Cold Rupture is a unique grand charm in Diablo II: Resurrected.
Like all other sundered charms, Cold Rupture only drops from boss pack monsters in Terror Zones on Hell difficulty. Many monsters in Hell difficulty are immune to cold, with such high resistances that a high level Lower Resist or Conviction is still inadequate to break them, so the sundering provided here makes cold-based classes much more valuable. Sorceresses that have invested some points into Cold Mastery can find great use in this, as Cold Mastery does nothing to cold-immunes. The 1/5th reduction to effectiveness still applies, but it is a good deal better than no resistance reduction at all.
