Phantom Zant

Phantom Zant is the mini-boss of the Palace of Twilight in.

Strategy
Phantom Zant is encountered twice in the Palace of Twilight. It throws balls of dark matter that spawn various Twilight monsters, such as Shadow Keese, Shadow Deku Babas, and Shadow Beasts. After Link defeats all the spawned monsters, or the monsters have remained for long enough, Phantom Zant will continue to warp around the room. Eventually, it will temporarily stop to spawn more monsters. It is at this time that Link is able to attack it. After defeating Phantom Zant, Link will be able to obtain a Sol, which he must return to the entrance of the palace.
