A Ko rune is a low-mid rune which can be socketed into equipment in Diablo II: Lord of Destruction. Ko runes are useful as part of the Heart of the Oak rune word, and in open and ladder games, upgrading unique armor to elite versions.

Effects[edit | edit source]

Socketing an item with a Ko rune increases the item's level requirement to 39, unless it was already higher.
