This phantom is the hardest boss in the game. To hurt him you need to use an attack that corresponds with the light over his head- if the light is yellow use lightning, blue use blizzard, red use fire, and if the light is white use normal attacks. The thing that will usually kill you when fighting the phantom is that he uses this spell that counts down your death (i think its 15 seconds). He uses the spell on Goofy and Donald first and does it to you last once they're dead. If you look at the clocktower, the minute hand of the clock will move along with the seconds you have left all the way to zero(which in this case is the 12). To postpone the spell you must use Stop on the clocktower minute hand causing it to stop the countdown. What you have to remember is that it will continue the countdown once its unfrozen and you also need to fill your items bag with elixirs so that you can replenish your magic points (since you'll be using magic on the phantom and Stop on the clocktower). The phantom has a lot of life so i recommend you get at a high level so you have a lot of magic points and can kill the phantom fast before the countdown ends. You also should have Stopga for that will stop the clock hand the longest.

You get stopga when you beat phantom!!!
