CemOhm is a legendary Runeword created by combining a Cem Rune of Ritual and a Ohm Rune of Invocation.
How to Create CemOhm
You can create CemOhm by adding the magic Cem Rune of Ritual and the legendary Ohm Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cem - Cast Evade. (75)
Ohm - Invoke the Barbarian's , increasing your damage dealt by 15% for 6 seconds. (600)

Overflow
CemOhm can not overflow because the amount of Offering you receive from the Cem 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.
