CemZid is a magic Runeword created by combining a Cem Rune of Ritual and a Zid Rune of Invocation.
How to Create CemZid
You can create CemZid by adding the magic Cem Rune of Ritual and the magic Zid Rune of Invocation to a two-socketed
Helm,
Chest Armor,
Pants, or
Two-Handed Weapon.
Overflow
When CemZid overflows, you receive the Zid Rune's overflow effect (Increase Damage) 2 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
