Diablo 4 Lum

Lum Rune is a Magic Rune of Invocation in Diablo IV: Vessel of Hatred. It restores a small amount of Primary Resource instantly and scales with Offering overflow. When paired with a Rune of Ritual, it forms a Runeword that can be socketed into dual-socket gear. Lum is ideal for resource-starved builds, channeling loops, and sustain-focused rotations.

“Even a spark is enough to reignite the flame."
