XolXan - Forbidden Extinction

XolXan is a legendary Runeword created by combining a Xol Rune of Ritual and a Xan Rune of Invocation.

How to Create XolXan

You can create XolXan by adding the legendary Xol Rune of Ritual and the legendary Xan Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.

Xol - Invoke a Skill from another Class. (150)

Xan - Your next attack will cause your hits to be a guaranteed Critical Strike and Overpower for 0.35 seconds. (300)

Overflow

XolXan can not overflow because the amount of Offering you receive from the Xol 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.
