PART 1: Go to the Malo Mart in Kakariko Village during the day. Inside,
talk to the old Goron holding the sign up and listen to his
pleas. Donate 1000 Rupees (does not have to be all at once).
PART 2: Second is the trickier part. Although the bridge will have been
repaired, you will have to donate again to the old Goron for
Malo to actually buy out Chudley's shop. Unfortunately, the
price this time comes to a whopping 2000 Rupees. Instead, there
is a way you can reduce this to 200 Rupees.
First, you must talk to the tattooed Goron whom is standing
right outside of the Malo Mart. He will remark on the west
bridge from the Castle Town being fixed. Warp to the Castle
Town, and go to the WEST END (not the south end - that bridge
is irrelevant) of the city. Exit out the gate here. Outside,
talk to the Goron to learn of his need for hot springwater.
Warp back to Kakariko Village, and talk to the tattooed Goron.
He shall then give you a barrel of hot springwater, launching
you into a mini-game where you must take the barrel to the
Goron on the west bridge. I recommend that you run around the
edge of the landmass going counterclockwise, making sure to
dodge all the hokoblin and kakarots that are patrolling the
border (you can do this by running past the archers while they
are facing the opposite way). If you ever run into any real
trouble, just drop the barrel down and quickly knock the enemies
down (killing them wastes tiem), then pick the barrel back up
and continue.
The only other thing of note is that there will be a false lead
in the form of a wooden bridge in the southwest corner - this
is NOT the bridge you want to go onto. Instead, continue north
until the map shows you as being right next to the correct
bridge, and head east. Z-Target the Goron after he finishes
talking, and throw the barrel after him. This is important;
you actually need to THROW IT AT HIM. Afterwards, claim a
Heart Piece that falls down, and head back to Kakariko Village.
Donate the 200 Rupees.
PART 3: Head to Castle Town. Go to the center square, and head to the
southwest section of this area, and enter the shop here. Inside,
you can now purchase the items at much lower prices than their
original costs. To get the Magic Armor, you must fork over 598
Rupees. If you can only carry up to 300 Rupees, you must go and
find at least one Golden Bug, and give it to Agatha in the
Hyrule Castle Town for a larger wallet (her house is in the
southeast alleyway).
