The Ultimate Key from Dragon Quest IX

The Ultimate key (sometimes called Final or Last Key) is a recurring item that is needed to unlock the barred jail doors. It is usually necessary to advance the later stages of the story.


Dragon Quest III[]

The Final Key is found at the Final Key Shrine, which requires a mini-quest to be completed in order to enter the shrine.


Acquiring the final key is one of the first major tasks the player must accomplish after receiving the ship in Portoga. It requires visiting at least 3 separate locations.


The village has an item shop which sells Invisibility herbs. These herbs turn the Hero's party invisible for a short amount of time. At least one herb is needed to proceed.


The castle is guarded so that outsiders may not enter by normal means. By using and invisibility herb, the hero's party can sneak by the sentries guarding the entrance. Inside, there is a boulder puzzle located on the second floor which must be solved. The player must push three boulders around water hazards into a straight line on the north wall. After successfully completing the puzzle, the hero is rewarded with the Vase of Drought.

North Central Sea and Final Key Shrine[]

In the north central sea (just north of where the 2 continent "arms" cross each other), there is a small grouping of shoals in a 'T' pattern. By guiding the ship adjacent to the south center shoal, the hero can use the Vase of Drought to raise the Final Key Shrine. Inside the shrine, the final key is located inside a chest.

Dragon Quest IV[]

The Ultimate Key is given by the Queen of Femiscyra after confronting the rosary thief. It is needed to obtain the Zenithian shield in the basement of Femiscyra Castle.

Dragon Quest V[]

The Ultimate Key is obtained after defeating Bjørn the Behemoose. It is necessary to open the door in the Estuary Sanctuary leading to the portal to Nadiria.

Dragon Quest IX[]
