lum rune

Diablo 2 Resurrected lum rune

A Lum rune is a low tier rune that can be socketed into armor and weapons in Diablo 2: Lord of Destruction and Diablo 2 Resurrected. A Lum rune provides +10 to Energy when inserted in any item.

Lum runes are most often used for upgrading exceptional elite weapons to elite unique weapons.

You can cube 3 Io runes and a flawed topaz together to get a Lum rune. You can also obtain a Lum rune from nightmare countess. You can get a Lum rune from the nightmare hellforge quest.

A Lum rune requires level 37 to use. When you socket an item with a Lum rune, you increase the level requirement to level 37, unless it was already higher.
