NocTzic is a rare Runeword created by combining a Noc Rune of Ritual and a Tzic Rune of Invocation.
How to Create NocTzic
You can create NocTzic by adding the rare Noc Rune of Ritual and the rare Tzic Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Noc - Inflict a Crowd Control that isn't Slow or Chill. (10)
Tzic - Invoke the Spiritborn's , dealing damage and Knocking Down enemies. (250)
Concussive Stomp
Overflow
NocTzic 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.
