BacOno is a legendary Runeword created by combining a Bac Rune of Ritual and a Ono Rune of Invocation.
How to Create BacOno
You can create BacOno by adding the legendary Bac Rune of Ritual and the magic Ono Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Bac - Travel 5 meters. (50)
Ono - Invoke the Druid's Dancing Bolts, seeking and dealing damage to enemies. (25)
Overflow
When BacOno overflows, you receive the Ono Rune's overflow effect (Increased Bolts Spawned) 1 times.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
