KaaLac is a rare Runeword created by combining a Kaa Rune of Ritual and a Lac Rune of Invocation.
How to Create KaaLac
You can create KaaLac by adding the rare Kaa Rune of Ritual and the rare Lac Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.

Challenging Shout
Overflow
KaaLac can not overflow because the amount of Offering you receive from the Kaa Rune exactly fills the required Offering of the Lac Rune.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
