Beyond dungeon items, several collectibles offer significant upgrades. Pieces of Heart, when collected in fours, increase your maximum health. Secret Seashells can be traded for the powerful Koholint Sword. Magic Rod is a powerful offensive item found later in the game. The Magnifying Lens is a key item from the trading sequence that reveals hidden text. Collecting these items is crucial for becoming stronger and uncovering all of Koholint's secrets.
