To obtain the Boss Key in the Wind Temple in "The Legend of Zelda: The Wind Waker," you need to navigate through the temple, solving puzzles and defeating enemies. First, activate the wind currents using the Deku Leaf to reach higher platforms. You'll need to collect the small keys to unlock doors and access the Boss Key chamber. Once you reach the Boss Key room, defeat the mini-boss to claim the key.
