NocLum is a rare Runeword created by combining a Noc Rune of Ritual and a Lum Rune of Invocation.
How to Create NocLum
You can create NocLum by adding the rare Noc Rune of Ritual and the magic Lum Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Noc - Inflict a Crowd Control that isn't Slow or Chill. (10)
Lum - Restore 2.5 Primary Resource. (5)
Overflow
When NocLum overflows, you receive the Lum Rune's overflow effect (Increased Resource Restored) 1 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
