Phantom Ganon's Sword
The Phantom Sword is a weapon from The Legend of Zelda: The Wind Waker. It can only be used when Link is in Ganon's Tower. It is carried by Phantom Ganon and is dropped by him when Link kills him.
Note: In the Phantom Ganon maze in Ganon's Tower, the hilt of the sword points to the next door Link needs to go through.
This weapon was also wielded by Phantom Ganon in the fiend's next appearance, Four Swords Adventures.
