Witch's Ring

The is an item featured in The Crystal Trap. Obtained from the Tree Witch, the ring is required to open the door that leads to the room guarding the Magnifying Glass, which is one of the items necessary to free Link from the Crystal.

Princess Zelda can only obtain the Witch's Ring if she chooses to stay and eat with the Tree Witch. For having had the courage to try the witch's stew, the old woman will reward her with the ring. Once the princess reaches the Cavern, she will come upon a door that will not open with the Large Brass Key, and the only way to open it is by inserting the Witch's Ring on the keyhole. This will cause for the locked door to swing open, allowing the young princess to retrieve the Magnifying Glass inside the chamber.
