NocRandom Rune is a rare Runeword created by combining a Noc Rune of Ritual and a Random Rune Rune of Invocation.
How to Create NocRandom Rune
You can create NocRandom Rune by adding the rare Noc Rune of Ritual and the magic Random Rune Rune of Invocation to a two-socketed Helm,
Chest Armor,
Pants, or
Two-Handed Weapon.


Overflow
NocRandom Rune can not overflow because the Random Rune Rune does not have an overflow effect.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
