An Io rune is a low-mid rune which can be socketed into equipment in Diablo II: Lord of Destruction. Io runes are somewhat rare, but their value tends closer to low runes, due to a lack of popular uses.
Effects
| Equipment type | Effects |
|---|---|
| Weapon | +10 To Vitality |
| Body armor or helm | +10 To Vitality |
| Shield | +10 To Vitality |
Socketing an item with an Io rune increases the item's level requirement to 35, unless it was already higher.
