Dark Hyrule Castle is the final dungeon, a twisted version of the familiar castle. It's filled with the toughest enemies and most complex puzzles in the game, often requiring the use of your Four Sword clones. You'll need to split Link into multiple copies to activate multiple switches simultaneously, push heavy blocks, and solve intricate floor puzzles.
The castle is divided into several sections, each leading to a mini-boss or a challenging puzzle. Be prepared for a series of intense battles as you ascend to Vaati's chambers. The dungeon culminates in a multi-phase boss battle against Vaati himself. Utilize all your items and the Four Sword's cloning ability to defeat him and restore peace to Hyrule. This final challenge will test every skill you've acquired throughout your adventure, demanding strategic thinking and precise execution.
