Heart Container

Link's health is symbolized throughout the The Legend of Zelda series (excluding The Adventure of Link) as a set of Hearts. As Link progresses through the games, he will require more and more health in order to survive the greater challenges. This additional health is acquired in the form of Heart Containers. A Heart Container is awarded after every major boss in the games, and can often also be manually built by acquiring four (or five in Twilight Princess) Pieces of a Heart.
