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


Overflow
NeoRandom Legendary Rune can not overflow because the Random Legendary 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.
