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


Overflow
ZanRandom 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.
