Instructions
Smash the vases inside the houses of Mido and the Three Kokiri Brothers in Kokiri Forest to gather rupees quickly, then head to the Kokiri Shop to purchase the Deku Shield. If you need additional rupees, cut tall grass and smash small stones.
Destroy vases inside the Hyrule gatehouse to earn rupees, then exit and re-enter the gatehouse to repeat the process. This is the fastest way to earn enough money to buy the Hylian Shield from the Hyrule Town Market while you are still a child.
Defeat the second Iron Knuckle you meet in the Spirit Temple to obtain the Mirror Shield. Using the Master Sword and Hylian Shield will only slow you down, so equip the Biggorons Sword -- this will allow you to defeat him in only four jump slashes.
