Hela's House of Dark Delights for Tunnels & Trolls

To your amazement, the Elfchild spits on the table. But instead of saliva, you see a plain copper ring. "Wear this," she tells you, "and you will be immune to infectious diseases. Furthermore, while wearing it, you will regenerate damage done in combat. (You will recover 1 point of damage every two minutes while wearing the ring, back to your normal CON rating.) But, if you ever lose the ring, or speak of its powers, they will vanish." You put on the ring. You now have your health. She takes you out of the House of Dark Delights.
