Piece of Heart

Pieces of Heart, sometimes capitalized Pieces Of Heart, are items in The Legend of Zelda series that represent a fraction of a complete Heart Container. When a certain number of Pieces of Hearts are collected, usually four, another heart is added to Link's health meter. Pieces of Heart first appear in The Legend of Zelda: A Link to the Past, where they replace the overworld Heart Containers from the first The Legend of Zelda game. Pieces of Heart resemble heart-shaped glass containers with a heart inside, similar to Heart Containers, except Pieces of Heart can be distinguished for encasing a smaller heart. Pieces of Heart are usually found throughout the overworld, within a Treasure Chest, or obtained for completing a sidequest.

In The Legend of Zelda: The Wind Waker, some Pieces of Heart are found within treasure chests that are sunk within the Great Sea. Link can use Treasure Charts to help find these treasure chests (although the charts do not explicitly list the locations of the Pieces of Hearts). When Link reaches a treasure chest location, he can use the Grappling Hook to pull it out. Several of these treasure chests contain a Piece of Heart. Additionally, the Island Hearts Chart shows islands with Pieces of Heart as well as amounts, though the shop trading sequence is listed as Windfall Island (where it starts) instead of Greatfish Island (where it ends).

Aside from usually being found on the overworld, some Pieces of Heart are located in dungeons, making it the second game where Pieces of Heart are found within dungeons. Every dungeon has a Piece of Heart except the Temple of Droplets and Dark Hyrule Castle. A Piece of Heart is often the reward for a Kinstone Fusion.

Hyrule Warriors series
In the Hyrule Warriors series, like most games of The Legend of Zelda series, four Pieces of Heart make up a Heart Container, which is then automatically added to the character's health bar. Pieces of Hearts are usually obtained from a treasure chest, which themselves usually appear after capturing certain keeps. Depending on the character used, the treasure chest might have a different reward than a Piece of Heart.
