PocQax is a rare Runeword created by combining a Poc Rune of Ritual and a Qax Rune of Invocation.
How to Create PocQax
You can create PocQax by adding the rare Poc Rune of Ritual and the rare Qax Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Poc - Spend 5% of your Maximum Resource. (2)
Qax - Your next non-Basic Skill cast spends all of your Primary Resource to deal up to 100% increased damage. (400)
Overflow
PocQax can not overflow because the amount of Offering you receive from the Poc 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.
