um rune

An Um rune is a mid tier rune that can be socketed into armor and weapons in Diablo 2: Lord of Destruction and Diablo 2 Resurrected. An Um rune provides All Resistances +20 when inserted in shields or off-hands, All Resistances +15 in body armor and headgear, and 25% Chance of Open Wounds in weapons.

You can cube 2 Pul runes and a flawed diamond together to get an Um rune. You can also obtain an Um rune from hell countess. You can get an Um rune from the nightmare hellforge quest.

An Um rune requires level 47 to use. When you socket an item with an Um rune, you increase the level requirement to level 47, unless it was already higher.
