AhuXan is a legendary Runeword created by combining a Ahu Rune of Ritual and a Xan Rune of Invocation.
How to Create AhuXan
You can create AhuXan by adding the legendary Ahu Rune of Ritual and the legendary Xan 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)
Xan - Your next Skill cast will be a guaranteed Critical Strike and Overpower. (700)
Overflow
AhuXan can not overflow because the amount of Offering you receive from the Ahu Rune exactly fills the required Offering of the Xan Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
