>>110915018They are the shovel equivalent; mole claws. Dig up really obvious patches of ground for treasure; think glowing spots in Wind Waker. Yes it's a terrible idea.
>>110914786There are three known shields in OoT, so I'd imagine there will be three lines of shields to accomodate each, such as:
Wooden->Reinforced->Plated, remember that the wooden shield has to be made whenever, it's never passed down.
Then there has to be the Hyrulian Shield line:
Iron->Reforged->Hyrulian
Then there has to be the Mirror Shield line:
Dull->Shiny->Mirror
However, there mightn't be a Mirror Shield, and there could be one shield you upgrade and upgrade until it's finally the Hyrulian shield. But either way, I'd imagine even 9 shields would be a conservative estimate.
