The Grand Ghost is a special Heartless introduced in Kingdom Hearts Final Mix. It shares similarities with the Search Ghost Heartless and drops the rare Frost Stone synthesis item.
The Grand Ghost Heartless is only found in the Stomach in Monstro. The Grand Ghost should be the only enemy that spawns in this area.
Rather than striking the Grand Ghost with the Keyblade or magic, the only way to deal damage is to use items like Potions, Hi-Potions, and Elixirs. You must select the "Ghost" option in the menu when using an item - this requires you to be close to the Grand Ghost. Locking on to it will help you ensure that the "Ghost" option becomes available as you approach.
The Grand Ghost has 300 HP, and the type of item determines how much damage is dealt to it. You can also obtain items to use against the Grand Ghost by performing certain actions:
Item/Magic Used | Damage / Effect |
---|---|
Potion | 50 Damage, drops HP orbs |
Hi-Potion | 70 Damage, drops HP orbs |
Mega-Potion | 100 Damage, drops HP orbs + Frost Stone (5%) |
Ether | 20 Damage, stuns for 2 seconds, drops MP orbs + Ether (30%) |
Mega-Ether | 50 Damage, stuns for 5 seconds, drops MP orbs + Ether (30%), Frost Stone (10%) |
Elixir | 200 Damage, 35 Munny, Frost Stone (35%) |
Megalixir | 300 Damage, 120 Munny, Frost Stone (20%), Frost Stone (100%) |
Deflect attack or attack while stunned | MP orbs, Potion (20%) |
Gravity | MP orbs, Hi-Potion (30%) |
Stop | MP orbs, Hi-Potion (20%) |
The Grand Ghost will always drop a Frost Stone as long as its HP is depleted. For a chance to obtain more Frost Stones from a single Grand Ghost, use higher quality items on the Grand Ghost (see the table above).
If you're trying to get the Grand Ghost to respawn, try leaving the world via gummi ship and immediately returning.
