AhuVex is a legendary Runeword created by combining a Ahu Rune of Ritual and a Vex Rune of Invocation.
How to Create AhuVex
You can create AhuVex by adding the legendary Ahu Rune of Ritual and the legendary Vex Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Ahu - Lucky Hit: Up to a [100|%|] chance against Injured enemies. (25)
Vex - Gain +3 to all Skills for 8 seconds. (1000)
Overflow
AhuVex can not overflow because the amount of Offering you receive from the Ahu Rune exactly fills the required Offering of the Vex Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
