Hearth

Hearth is a defensive helm runeword in Diablo 2 Resurrected introduced in Patch 2.6 that specializes in cold resistance and freeze immunity. Created with Shael + Io + Thul in any 3-socket helm, it's the most versatile of the elemental resistance helms thanks to its Cannot Be Frozen modifier.

Cold Defense and Freeze Immunity

Hearth provides Cold Resist +40-60%, the rare Cold Absorb +10-15% modifier that converts incoming cold damage into healing, and crucially, Cannot Be Frozen. This makes it excellent against cold-heavy bosses like Duriel, Diablo, Baal, and Izual. The Cannot Be Frozen effect is particularly valuable—the only other helm runeword with this is Wisdom at level 45, making Hearth accessible 10 levels earlier.

Best Uses and Bases

Use Hearth as a budget alternative to Vampire Gaze or as a swap helm for cold-heavy areas. The helm also provides +20% Faster Hit Recovery, +75-100% Enhanced Defense, +10 to Vitality, and Increase Maximum Life 5%. Barbarians and Druids should use class-specific helms with +skills. All three runes drop from Nightmare Countess.
