KaaQue is a rare Runeword created by combining a Kaa Rune of Ritual and a Que Rune of Invocation.
How to Create KaaQue
You can create KaaQue by adding the rare Kaa Rune of Ritual and the rare Que Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.

Overflow
KaaQue can not overflow because the amount of Offering you receive from the Kaa Rune exactly fills the required Offering of the Que Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
