These items can be collected and used to either upgrade your sword, make potions, or to help retrieve a grieving mother’s lost children. Some are found everywhere, while others can be downright aggravating to obtain, but all are worth the effort of collecting.
Monster Tail
Description: Collect 10 of these blue monster tails, and the Witch will make them into a blue potion.
Location: These are random drops from fallen enemies, skulls, pots, and tall grass and bushes in Hyrule, Lorule, and the dungeons.
Monster Gut
Description: Collect 10 of these purple monster guts, and the Witch will make them into a purple potion.
Location: These are randomly dropped from slain enemies, skulls, pots, and tall grass and bushes in Hyrule, Lorule, and the dungeons.
Monster Horn
Description: Collect 10 of these yellow monster horns, and the Witch will make them into a yellow potion.
Location: These are random drops from destroyed enemies, skulls, pots, and tall grass and bushes throughout Hyrule, Lorule, and the dungeons.
Lost Maiamais
Description: These aquatic shellfish are lost and must be recovered and brought back to Mother Maiamai. They let out a chirping sound when Link is close to one, so keep that volume up!
Location: One hundred lost Maiamais are spread all over Hyrule and Lorule, underwater and on land. Some are in plain sight, while others are hidden. Try lifting rocks, searching the walls behind houses, or ramming into trees with the Pegasus Boots to uncover them.
Piece of Heart
Description: A piece of heart is equivalent to one quarter of a full heart container. So for every four he finds, Link gains an extra heart in his life gauge.
Location: These are scattered throughout Hyrule and Lorule, and are often just out of reach until you’ve gained certain quest. Note any of these that Link cannot reach at first, so you can return to retrieve them when Link is more capable.
Master Ore
Description: This very rare ore is used to upgrade the Master Sword, making it even more masterful. Definitely make finding these a priority, because there are only four in existence. Take the first two to the Blacksmith in Hyrule to gain a Level 2 Master Sword. Bring the last two to the Blacksmith in Lorule to create the devastatingly powerful Level 3 Master Sword!
Location: Three pieces of Master Ore can be found in large chests in Skull Woods, Thieves’ Hideout, and the Dark Palace, all located in the dark world. Find the fourth in the secret entrance in the back of the Sanctuary in Hyrule.
