In the Dragon Quest 3 HD-2D Remake, obtaining the Ultimate Key is crucial. There are numerous locked doors scattered across the red, blue, and silver map. The Thief’s Key opens red doors, the Magic Key unlocks blue doors, and the Ultimate Key grants access to all doors. It’s wise to locate the Ultimate Key as early as possible since many valuable items and equipment are hidden beyond these locked doors.
To access the Ultimate Key, you first need to procure black pepper for the king of Portoga. This task is necessary to receive his ship, which allows you to navigate the seas in search of the Ultimate Key. After acquiring the ship, you will sail the world to collect orbs needed to awaken the Everbird and confront the boss, Baramos. However, unlike the other two keys, locating the Ultimate Key involves a multi-step process that requires another essential artifact: the Bottomless Pot.
Where to Find the Ultimate Key Part 1 (Bottomless Pot Puzzle)
Obtaining the Bottomless Pot
Your first task in finding the Ultimate Key is to secure the Bottomless Pot. This item can be found on the northwestern island of Edina, which is guarded by sentinels that prohibit entry to outsiders. Use the Fade spell or a Fading Jenny to make yourself and your party invisible, enabling you to sneak past the guards and reach the castle’s basement.
Once in the basement, you’ll face a puzzle requiring you to position three rocks onto pressure plates without pushing them into the water. Should you make a mistake, the puzzle can be easily reset, so there’s no need to stress over errors. Completing the puzzle opens a door at the back of the room, leading to a chest containing the Bottomless Pot along with a quirky note about its function.

Where to Find the Ultimate Key Part 2 (Shallow Shrine Location)
Beginning at Shrine of the Dwarf
Once you’ve acquired the Bottomless Pot, set your course for the center of the northern ocean, situated between the northeastern and northwestern continents. The Shrine of the Dwarf, located at the snowy edge of a vast forest area, is an ideal place to start your journey. After sailing eastward for a while, you’ll encounter a series of large rocks marking the entrance to the Shallow Shrine, where the Ultimate Key is concealed.
When you get to the rocks, a prompt will ask if you want to drop the Bottomless Pot into the water. Choose “Yes” to trigger a cutscene that unveils the Shallow Shrine hidden beneath the waves, allowing your party to enter its depths. Once inside, you can open the chest located in the center of the room to claim the Ultimate Key.
A Mini Medal is hidden on the ground just north of the chest containing the Ultimate Key.
