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

Horrid Decrepify
Overflow
KaaWat can not overflow because the Wat Rune does not have an overflow effect.
Overflow occurs when your Ritual generates more Offering than required for the Invocation. The overflow effect is proportional to the amount Offering overflows.
