KaaTeb is a rare Runeword created by combining a Kaa Rune of Ritual and a Teb Rune of Invocation.
How to Create KaaTeb
You can create KaaTeb by adding the rare Kaa Rune of Ritual and the magic Teb Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Kaa - Lose 1% of your Maximum Life. (2)
Teb - Evoke the Necromancer's , counterattacking damage from enemies and Healing you when they die. (100)

Overflow
KaaTeb can not overflow because the Teb 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.
