KaaQax is a rare Runeword created by combining a Kaa Rune of Ritual and a Qax Rune of Invocation.
How to Create KaaQax
You can create KaaQax by adding the rare Kaa Rune of Ritual and the rare Qax Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Kaa - Lose 25% of your Maximum Life. (50)
Qax - Your next non-Basic Skill cast spends all of your Primary Resource to deal up to 100% increased damage. (400)
Overflow
KaaQax can not overflow because the amount of Offering you receive from the Kaa Rune exactly fills the required Offering of the Qax Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
