An ultra rare artifact class item that is in the possession of Ainz Ooal Gown.
In the Anime, it is depicted as a translucent green stone, embedded in a silver ring.
This ring allows the wearer to make one wand usable by anyone regardless of class. However, it has a one-hour cool-down before it can be used on a different wand. Also, it has drawbacks like draining the wearer's mana.
- This ring was an ultra-rare artifact dropped by a boss monster.
- Ainz was using the one Amanomahitotsu had given him when he left the game.
- Ainz wears this ring on his right thumb.
