Blue Ore

Blue Ore is an item from The Legend of Zelda: Oracle of Seasons. It is used along with Red Ore in order to make Hard Ore. The hard ore can then be taken to the Subrosian Smithy along with a Wooden Shield to upgrade the shield to the Iron Shield.

Blue Ore can be found in a chest just north of the Strange Brothers house. To reach it, Link must have the Roc's Feather and Magnetic Gloves.
