KaaOno is a rare Runeword created by combining a Kaa Rune of Ritual and a Ono Rune of Invocation.
How to Create KaaOno
You can create KaaOno by adding the rare Kaa Rune of Ritual and the magic Ono Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Kaa - Lose 25% of your Maximum Life. (50)
Ono - Invoke the Druid's Dancing Bolts, seeking and dealing damage to enemies. (25)
Overflow
When KaaOno 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.
