IgniZid is a legendary Runeword created by combining a Igni Rune of Ritual and a Zid Rune of Invocation.
How to Create IgniZid
You can create IgniZid by adding the legendary Igni Rune of Ritual and the magic Zid Rune of Invocation to a two-socketed
Helm,
Chest Armor,
Pants, or
Two-Handed Weapon.
Overflow
IgniZid can not overflow because the amount of Offering you receive from the Igni Rune exactly fills the required Offering of the Zid Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
