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


Overflow
AhuQax can not overflow because the amount of Offering you receive from the Ahu Rune exactly fills the required Offering of the Qax Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
