Also called the "Ring of the Vampire King Nurmaha", nicknamed "Absolute Ring."
Clementine was the only one who was able to obtain this artifact due to being the only one to achieve the impossible achievement of killing the Carnivorous Beast during the first week in the Tutorial. In the first timeline, people flipped the Otherworld upside down to try to find this ring after seeing Clementine cause a massacre. Kang Hansoo was able to discover its location when he went back in time and became the 2nd person to kill the Carnivorous Beast.
Nurmaha's Ring is a Growing Artifact that has eight abilities, each unlocked after feeding it runes to the next color.
The currently known abilities are:
- Power Destruction: Allows the user to destroy skills and temporarily cancel traits for an appropriate amount of mana. Unlocked when the artifact runes are Colorless.
- Hemorrhage: Wounds will stay open and bleed, preventing regeneration to a certain extent. Unlocked when the artifact runes are Red.
- Sense Destruction: Strongly reduces the senses of the target and disorients them. Unlocked when the artifact runes are Orange.
- Vampiric Effects: Lifesteal. Absorbs the life of another to heal the user. Unlocked when the artifact runes are Yellow.
- Physical Resistance Nullification: Nullifies the physical resistance which God had given to all creatures. Uses a massive amount of mana. Unlocked when the artifact runes are Green.
- Blue power - ???: Unlocked when the artifact runes are Blue.
- Indigo power - ???: Unlocked when the artifact runes are Indigo.
- Violet power - ???: Unlocked when the artifact runes are Violet.
Multiple powers can be used simultaneously, but the amount of mana needed is prohibitive. The powers comes into effect when someone is scratched by an attack imbued with the power. One of the fault is it does not work against insect. Vampiric Effects does not work on the Avatars/Players of Exodus in the Green Zone.
