Rings of regeneration should drain your Pw instead of your nutrition. When you’re at 0Pw, you stop regenerating.

Minor artifact ring of regeneration whose main ability is not making you hunger any faster than normal while wearing it.

Merge the rings of slow digestion and regeneration. Keep the name “regeneration”; make it chargeable. A positive rate boots your regeneration and your hunger rate, up until they are doubled at +10; a negative rate decreases both until they are halved at -10, with the intermediate values scaling as appropriate.

Possibly, since the extremes of &177;10 are hard to attain, make the doubling/halving threshold at &177;7 instead.

Hungerful regeneration from the ring only costs excess nutrition if your HP is actually below full. Possibly, to compensate for not having to micromanage your ring finger, accelerate the hunger rate while regenerating HP: instead of double, perhaps triple or quadruple its usual rate.

When you equip a ring of hunger or conflict (or regeneration), you get a message about feeling hungrier.

Rings of regeneration are chargeable. While positively enchanted ones drain nutrition to increase your life, negatively enchanted ones sap your life to increase your nutrition.
