XolThul - Forbidden Absolute Zero

XolThul is a legendary Runeword created by combining a Xol Rune of Ritual and a Thul Rune of Invocation.

How to Create XolThul

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

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

Thul - Invoke the Sorcerer's

Mystical Frost Nova

, inflicting Freeze and Vulnerable onto enemies. (300)

Overflow

XolThul can not overflow because the amount of Offering you receive from the Xol Rune exactly fills the required Offering of the Thul Rune.

Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
