CirQua is a magic Runeword created by combining a Cir Rune of Ritual and a Qua Rune of Invocation.
How to Create CirQua
You can create CirQua by adding the magic Cir Rune of Ritual and the magic Qua Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cir - Cast 5 Skills then become exhausted for 3 seconds. (300)
Qua - Gain 10% Movement Speed for 5 seconds, up to 50%. (50)
Overflow
When CirQua overflows, you receive the Qua Rune's overflow effect (Increased Duration) 5 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
