UrTzic is a rare Runeword created by combining a Ur Rune of Ritual and a Tzic Rune of Invocation.
How to Create UrTzic
You can create UrTzic by adding the magic Ur Rune of Ritual and the rare Tzic Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Ur - Your Minion or Companion kills an enemy or dies. (10)
Tzic - Evoke the Spiritborn's , dealing damage and Knocking Down enemies. (250)
Concussive Stomp
Overflow
UrTzic 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.
