Magic Armor

The Magic Armor is a special barrier, in the form of magic or a tunic, that greatly reduces the amount of damage Link receives from enemies during battle. The Magic Armor has a catch though: in order for it to function properly, it must capitalize on the longevity of Link's magic meter, like in The Wind Waker or the amount of rupees Link has, like in Twilight Princess.

The Wind Waker

 * See also: Island Trading Sequence

In The Wind Waker, the Magic Armor appears as a kind of jewel or crystal (which somewhat resembles Din's Fire from Ocarina of Time). It is an optional item in the game that can be obtained after completing the Island Trading Sequence.

Upon use, a magical barrier will cover Link, protecting him from taking damage, similar to Nayru's Love. The Magic Armor slowly drains Link's magic power while active, and will simply stop working once Link's magic meter runs out. Link can even activate the shield while sailing for protection from attacks during sea battles.

Twilight Princess

 * ''See also: Magic Armor Sidequest

The Magic Armor is an item in Twilight Princess that Link can use to make himself invincible. With the lack of a magic bar in Twilight Princess, the Magic Armor drains Rupees very quickly (about two per second). When attacked, it will drain 12 Rupees. Once Link runs out of Rupees, the armor becomes very heavy, causing Link to move as if he has the Iron Boots equipped. If Link is out of Rupees when he equips this, Link can not get on Epona, and if Link equips it while riding Epona, Epona will stop, and Link will be sent flying off of Epona. He also sinks in water if he runs out of Rupees while swimming, forcing him to take the armor off or drown. The Magic Armor's design is similar to that of the crown and armor Princess Zelda wears, suggesting that the Royal Family had something to do with the making of the armor. Another possible connection to the Royal Family is the Triforce symbol near the bottom of the torso.

Once Link has donated to the Malo Mart Castle Town Branch, the Magic Armor will be available for purchase at 598 Rupees.

Because of its Rupee-draining qualities, many players seldom equip this armor. However, this is not quite as much of a problem after breaking the curse on Jovani.

Obtaining the Magic Armor
The quest for the Magic Armor can be started after completing the Lakebed Temple. During his visit to Kakariko Village, Link finds in Malo Mart a Goron who reunites funds to repair a bridge that gave access to Hyrule Castle Town from western Hyrule Field, which is important to resume the import of Hot Spring Water to said town. The name of this Goron is Gor Ebizo, who also (with the help of Malo himself) wants to put to an end the difficult economic situation in Castle Town by buying the most luxurious and expensive shop to replace it with one having cheaper products. He needs a total donation of 1000 Rupees, which Link can provide through various partial donations (unless he can donate that amount at once). After the donation, Link must talk to Gor Liggs, who is outside Malo Mart, who will request that the young hero go to western Hyrule Field to see the progression of the bridge's repair.

Although a Goron managed to repair the bridge, he got critically fatigued after that, and therefore can't bring Hot Spring Water to the town anyway. After Link speaks to him, he returns to Kakariko Village, where Gor Liggs gives him a barrel of Hot Spring Water to revitalize the tired Goron. Link crosses the western field with the barrel, but it's not a task without obstacles. Numerous enemies, including Leevers and Bokoblins, will be there to annoy Link, and if something happens to the barrel, the young hero will have to return to Kakariko Village for another. Once he reaches the bridge, he throws the barrel to the Goron, who quickly regains his strength and begins the Hot Spring import, leaving a Heart Piece in the process.

Afterward, Link must go back to Malo Mart in Kakariko Village to find that another money collection began, this time to buy Chudley’s Fine Goods and Fancy Trinkets Emporium. The money needed is a mere 200 rupees (this is because, thanks to the export of Hot Spring Water, both Malo and Gor Ebizo gained a lot of money and they're reserving it to the shop purchase. Had Link ignored helping Gor Link's son, the money he would have needed was 2000 rupees). After the donation, the final objective is complete. Link must now go to Castle Town to find a branch of Malo Mart where the Emporium used to be. Inside, he can find various goods at reasonable prices, including the Magic Armor for 598 rupees.

Trivia

 * In The Wind Waker, after Link has finished the game and is wearing the normal island clothes for the second quest, the magic armor will still show the outline of Link's trademark hat even though he is not wearing it. Some theorize that this is the silhouette of the invisible "Hero's New Clothes".
 * Interestingly, both Magic Armor sidequests (the trading sequence in The Wind Waker and the donations in Twilight Princess) include the obtention of a Heart Piece; this may be to compensate the high inversion of rupees in the quests.
