TamOhm is a legendary Runeword created by combining a Tam Rune of Ritual and a Ohm Rune of Invocation.
How to Create TamOhm
You can create TamOhm by adding the legendary Tam Rune of Ritual and the legendary Ohm Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Tam - Cast a non-Channeled Core Skill. (25)
Ohm - Invoke the Barbarian's , increasing your damage dealt by 15% for 6 seconds. (600)

Overflow
TamOhm can not overflow because the amount of Offering you receive from the Tam 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.
