CirTzic is a rare Runeword created by combining a Cir Rune of Ritual and a Tzic Rune of Invocation.
How to Create CirTzic
You can create CirTzic by adding the magic Cir Rune of Ritual and the rare Tzic Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cir - Cast the same non-Channeled Skill 3 times in a row. (50)
Tzic - Invoke the Spiritborn's , dealing damage and Knocking Down enemies. (250)
Concussive Stomp
Overflow
CirTzic can not overflow because the Tzic Rune does not have an overflow effect.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
