Hero's Charm

    The Hero's Charm is a magical mask that, when equipped, shows the enemy's health while they're L-targeted.  To get this item you must have at least 41 Joy Pendants, which you can gather from various dungeons, and collect from defeated bokoblins (or alternatively, you can pull the Pendants from them with your Grappling Hook).  When you have collected 41 Joy Pendants, return to Windfall Island (D2) and head to Miss Mary, the school teacher.  Talk to her and she'll tell you how everything seems so joyful on Windfall... exept for a troublesome gang of children, the Killer Bees.  she askes you to talk to their leader, Ivan (the one with the picasso hat), and straighten them out.  Leave and find the roaming gang at the plaza.  Talk to Ivan and he challenges you to a hide-seek-and-run game.  If you accept, all the Killer Bees dash off in different directions.  It's up to you to find them!

    Once you find and capture all of them, you find your self back at the plaza in front of Miss Mary's school.  Then Ivan promise you that the Killer Bees won't cause any more trouble for anybody.  He also pleads for link to apologize to Miss Mary for them.  To do so, head into the school, talk to Miss Mary, and head back out to the Killer Bees.  They're so happy and thankful that they give you a Piece of Heart and a Piece of advice.  They tell you that they heard that Miss Mary likes Joy Pendants. Now, head back into the school and show Miss Mary your Joy Pendants three times.  On the third time she should be so pleased with all the Joy you have brought her that she will give you the Hero's Charm.

Magic Armor

    After you get the sail from Zunari,head indoors and come back out and talk to him to see that he now has new merchandise and a dream of becoming the worlds most successful merchant, but he needs an errand boy.  That's right, you!  If you accept his offer, he gives you a complementary town flower and a speech about how he wants to build on his Merchant's Oath.  As soon as your finished talking to him, three wandering merchants appear on the island across the Great Sea, one at Bomb Island, one at Greatfish Isle, and the last at Mother and Child Isles.  Leave Windfall and set sail for Mother and Child Isles (NOTE: The Ballad of Gales helps immensely in this spread out trading quest.). Do not warp to Mother and Child Isles or you will get stuck inside Mother isle and have to warp out again, but you can warp to Tingle Island and sail northwest to Child Isle, where the first merchant awaits you.  Talk to him and he tells you about his life as a wandering merchant.  Now show him the Town Flower and he asks if you want to trade the Town Flower For his Sea Flower.  If you accept, he asks for a minimal fee of around 20 rupees.  He then tells you that in accordance with the Merchant's Oath, he will send a supply of the Sea Flowers to Zunari's stall.  Your next destination is Greatfish Isle (B4), which you can warp directly to with the Ballad of Gales.  Sail to the left side of the island where you will find a raft with the second wandering merchant.  Climb aboard the raft and talk to the wandering merchant to go through the same bit of diologue as before.  Next show him the Sea Flower and he offers to trade you an Exotic Flower for around 25 rupees.  Again, you get the part about the Merchant's Oath, and a promise of a package to be sent to Zunari's stall. Now, if you keep trading among the various merchants, you will eventually get a Piece of Heart.
