Boss Battle: The Possessed Armor
The portal on the terrace is still open! Now or never! Defeat King Boo!
Examine the statue with the dark moon piece and how could it be otherwise, a fight begins. The tactics are the same as a few missions ago. This time, lock both armor on a carpet and pull on this one. After the attacks, avoid the master spirit and remove the first skin from it.
The second round will be a bit more difficult because you now have to lure three armor on a carpet to bring them down.
In the third round, a giant armor enters the field. Make sure both feet are on a carpet. Then, one by one, pull the legs away from the armor and the Master Spirit is waiting to be captured. After that, you own the last piece of the Dark Moon.
