Ring of Being Anchored in Time

Ring, rare (requires attunement)

The ring of being anchored in time renders its wearer immune to all forms of time manipulation. It also slows the effects of time on the wearer by 50 percent; the wearer ages a year for every two years that pass normally, needs to take a long rest half as often to remain rested and healthy, and needs only half as much food and drink as normal.

There is a cost; after finishing a long rest, the wearer must make a successful DC 10 Constitution saving throw or gain one level of exhaustion.

The ring consists of a plain platinum band with a setting that holds two triangular stones, one star sapphire and one obsidian, with their points touching so they resemble an hourglass.
