Piece of Heart

A classic Zelda item. Four Pieces of Heart are required to form one Heart Container in most Zelda games. Pieces of Heart are scattered all across Hyrule and the subsidaries of the mainland. Link can usually acquire a Piece of Heart by completing a task, reaching an out-of-the-way area through use of a special item, or from within dungeouns and temples. Pieces of Heart are usually part of a sidequest related to the gamebut are not at all necessary to the game's completion.

The Legend of Zelda: Twilight Princess breaks the tradition set in The Legend of Zelda: A Link to the Past and requires that five Pieces of Heart be collected to complete a Heart Container.
