Dungeon - Zelda Dungeon Wiki, a The Legend of Zelda wiki

Dungeons appear in every single The Legend of Zelda game in one form or another. Usually going through a Dungeon follows a specific pattern: obtain a Map, Compass, and a Boss Key/Big Key in that order, obtaining Small Keys and a main Dungeon item(s) along the way, then defeat a Boss using said item, completing the said Dungeon. Completing Dungeons require puzzle solving and combat. The following is an outline of what Dungeons are like in different games.
