Subrosian Wilds

The Subrosian Wilds is an area to the far west of Subrosia, and Link is able to complete his quest without visiting this area once. However, if he does visit this area after obtaining the Magnetic Glove, he will be able to find a Magic Ring and the Blue Ore. The former is buried in the south-west corner of the area, and the latter is inside a treasure chest, and will be required if Link is to obtain the Iron Shield.
