An Ohm rune is a high rune which can be socketed into equipment in Diablo II: Lord of Destruction. Ohm is valued for its rarity, and for its use in a few popular rune words such as Call to Arms.


Equipment type Effects
Weapon +50% Enhanced Damage
Body armor or helm 5% To Maximum Cold Resist
Shield 5% To Maximum Cold Resist

Socketing an item with an Ohm rune increases the item's level requirement to 57, unless it was already higher.


The Act 2 (H) Good treasure class has a chance to drop an Ohm rune, as do higher Good treasure classes.

In single-player, open or ladder games only, the Horadric Cube can transmute two Vex runes and one normal emerald into one Ohm rune.
