Heart Containers are recurring items in The Legend of Zelda series. They increase Link's maximum number of hearts by one, also refilling his hearts to full if he has lost any. They are most commonly found after defeating a dungeon's boss, but can also be found scattered around the landscape, usually in hidden locations. Occasionally, they can be obtained by completing difficult side quests.
