IgniOhm is a legendary Runeword created by combining a Igni Rune of Ritual and a Ohm Rune of Invocation.
How to Create IgniOhm
You can create IgniOhm by adding the legendary Igni Rune of Ritual and the legendary Ohm Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Igni - Stores offering every 0.3 seconds. Cast a non-Basic Skill to gain the stored offering. (Up to 500 Offering). (25)
Ohm - Invoke the Barbarian's Skill, increasing your damage dealt by 15% for 6 seconds. (600)

Overflow
IgniOhm can not overflow because the amount of Offering you receive from the Igni 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.
