LithTeb is a legendary Runeword created by combining a Lith Rune of Ritual and a Teb Rune of Invocation.
How to Create LithTeb
You can create LithTeb by adding the legendary Lith Rune of Ritual and the magic Teb Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Lith - Stand still while fighting for 0.31 seconds. (25)

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