Iron Shield

The Iron Shield is an item seen in The Legend of Zelda: Oracle of Ages and The Legend of Zelda: Oracle of Seasons. It is the second-most powerful shield seen in those games, being capable of deflecting more damage than the Wooden Shield but not as many as the Mirror Shield.

Oracle of Ages
In Oracle of Ages, Link's inventory has been stolen by the Tokay and taken to Crescent Island. To reclaim his belongings, he must speak with each thief one-on-one. On the southern coast of the island is a cavern which he can only reach by swimming, where he will find one of the thieves hiding. Instead of returning Link's Wooden Shield, however, the Tokay instead presents him with the Iron Shield.

Oracle of Seasons
In Oracle of Seasons, Link can acquire the Iron Shield in Subrosia by first obtaining a piece of Hard Ore. If he brings the Hard Ore and his Wooden Shield to the Subrosian blacksmith, the two items can be smelted together to create the Iron Shield.
