Enhanced Defense is a magical skill featured in The Legend of Zelda series. The various ways to acquire enhanced defense utilize differing methods in each game.
The Legend of Zelda
In The Legend of Zelda, Link can acquire two rings that enhance his defensive abilities:
The Blue Ring reduces damage Link takes in half and turns Link's tunic blue. Link can find it beneath an Armos in the overworld or buy it from the Merchant for 250 Rupees.
The Red Ring reduces damage to a quarter of its original amount and turns Link's tunic red. It is found in Level-9.
The Adventure of Link
In The Adventure of Link, Link can use the Shield Spell to enhance his defense, reducing the damage he takes by half. Link's tunic turns red, and the effect of the spell will wear off as soon as Link leaves to another area. It can be found in Rauru Town. In addition, every time Link's life level goes up via experience points, it will decrease the damage he takes permanently.
A Link to the Past
In A Link to the Past, Link's defense is enhanced by his tunics.
Link's Awakening DX
In Link's Awakening DX, after completing the Color Dungeon, Link can choose either the Blue Clothes, or the Red Clothes as a reward. The Red Tunic doubles attack power, while the Blue Tunic halves the damage Link takes.
Ocarina of Time
In Ocarina of Time, enhanced defense is awarded to Link by the Great Fairy of Courage who lives in a hidden cave by Ganon's Castle in Link's Adult time. The entrance is blocked by a black rock which can only be removed by the use of the Golden Gauntlets.
In Skyward Sword, Link can purchase Guardian Potions from the Potion Shop at the Bazaar. This Potion, when drunk, halves the damage dealt to Link by half for three minutes. By upgrading it to the Guardian Potion +, the Potion will make Link completely invincible for three minutes.
