Blue Ring

The Blue Ring is a recurring item in the, first appearing in The Legend of Zelda.

The Legend of Zelda
In The Legend of Zelda, the Blue Ring is a defensive artifact that cuts all damage Link takes in half. It is not as powerful as the Red Ring, which reduces damage to a quarter of its original amount. From the starting point, Link must travel north one screen, west three screens, north three screens, and look beneath the Armos Statues. The Merchant in the secret shop there sells the Blue Ring for 250 Rupees. In the Second Quest, it is located in the furthest northeastern corner of the overworld map. Once worn, Link's tunic changes to a periwinkle color. Wearing the Blue Ring will also cause Princess Zelda's dress to appear the same color.

Oracle of Ages
The found in Oracle of Ages has the same effect as the one found in the original : reducing all damage that Link takes by half. However, it does not change the color of his tunic.

Four Swords Adventures
Although the Blue Ring does not appear in, the Blue Bracelet found in each stage serves the same purpose.

The Shadow Prince
In The Shadow Prince, the Blue Ring makes another appearance, although its use is completely different from the one seen in the games and actually leads to a Game Over if Link receives this item. The young hero can obtain the Blue Ring from Charles of Moria if he decides to stay at North Castle and chooses to fight Charles after he hears him talking to some monsters. Link drops down from the tree and demands that Charles stop his evil magic, challenging him to a fight. Confused, the Morian knight tells the young hero that he just wants to be his friend, and gives him a Blue Ring as part of a Morian custom of exchanging gifts.

Later on in the book, after Link finds out that Charles is actually Ganon in disguise, he follows the false Morian knight into the woods but is promptly surrounded by a gang of Moblins. Link confidently reaches into his pocket and pulls out the blue ring that Charles gave him, which causes for the knight and the Moblins to take a step back. The young hero then reminds Charles that it was the magic ring that he gave Link as a token of friendship, and Charles begins to look nervous. Link guesses that from the way Charles is reacting that the ring must be powerful, but Charles just mocks him when suddenly blue smoke rises from the ring. This causes the young hero to begin to feel weak and eventually collapses. The page ends with a Game Over as Charles laughs at Link and pokes the young hero's weakened body.
