CemTeb is a magic Runeword created by combining a Cem Rune of Ritual and a Teb Rune of Invocation.
How to Create CemTeb
You can create CemTeb by adding the magic Cem Rune of Ritual and the magic Teb Rune of Invocation to a two-socketed Helm, Chest Armor, Pants, or Two-Handed Weapon.
Cem - Cast Evade. (75)
Teb - Invoke the Necromancer's , counterattacking damage from enemies and Healing you when they die. (100)
Abhorrent Iron Maiden
Overflow
CemTeb 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.
