ZanOhm is a legendary Runeword created by combining a Zan Rune of Ritual and a Ohm Rune of Invocation.
How to Create ZanOhm
You can create ZanOhm by adding the magic Zan Rune of Ritual and the legendary Ohm Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Zan - Cast an Ultimate Skill. (150)
Ohm - Invoke the Barbarian's , increasing your damage dealt by 15% for 6 seconds. (600)

Overflow
ZanOhm can not overflow because the amount of Offering you receive from the Zan Rune exactly fills the required Offering of the Ohm Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
