ZanTzic is a rare Runeword created by combining a Zan Rune of Ritual and a Tzic Rune of Invocation.
How to Create ZanTzic
You can create ZanTzic by adding the magic Zan Rune of Ritual and the rare Tzic Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Zan - Cast an Ultimate Skill. (150)
Tzic - Invoke the Spiritborn's , dealing damage and Knocking Down enemies. (250)
Concussive Stomp
Overflow
ZanTzic 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.
