XolQax is a legendary Runeword created by combining a Xol Rune of Ritual and a Qax Rune of Invocation.
How to Create XolQax
You can create XolQax by adding the legendary Xol Rune of Ritual and the rare Qax Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Xol - Evoke power from another Class. (150)
Qax - Your next non-Basic Skill cast spends all of your Primary Resource to deal up to 100% increased damage. (400)
Overflow
When XolQax overflows, you receive the Qax Rune's overflow effect (Further Increased Damage) 0.13 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
