An Ohm rune is a high tier rune that can be socketed into armor and weapons in Diablo 2: Lord of Destruction and Diablo 2 Resurrected. An Ohm rune provides +5% to Maximum Cold Resist when inserted in shields or off-hands, body armor and headgear, and +50% Enhanced Damage in weapons.
You can cube 2 Vex runes and an emerald together to get an Ohm rune.
An Ohm rune requires level 57 to use. When you socket an item with an Ohm rune, you increase the level requirement to level 57, unless it was already higher.
