What Is The Ultimate Key In Dragon Quest 11?

So what exactly is the Ultimate Key? Well to put it simply, it is an item that can open any door in the entire game. And when I say any door, I really do mean it. This also includes those doors that might otherwise require other special keys like the Magic Key to access. The Ultimate Key essentially makes every one of its peers redundant.

And yes, this key can also open the mysterious grey gates that you might have encountered during your incredibly long journey through the world of Erdrea. It’s actually safe to say that these doors are the main reason you would want to look for the Dragon Quest XI Ultimate Key in the first place because no other key can open them. Now let’s take a look at where to actually find this key.

How To Find The Dragon Quest 11 Ultimate Key?

As mentioned above, the Ultimate Key is a postgame item. In order to get it, you first have to beat the lengthy main game and allow the credits to roll. After this, you can continue your save game, at which point you should be greeted with the screen above. What follows directly after is spoiler territory, so we’ll skip past that.

Simply play through a bit more of the game, and after a point, you’ll be asked to visit the Havens Above area. This is the location you visit after you head to the Emerald Coast and meet with the Seer for the first time. She asks you to play the Calamus Flute item to summon a flying whale creature that takes you to Havens Above.

Once you’re finally here, a few brief cutscenes should play out. After the end, a single chest should be seen in the middle of the plaza next to some grass. The Dragon Quest 11 Ultimate Key can be found inside. Grab it.

Ultimate Key Door Locations

Now with the key in your possession, let’s take a look at all of the special doors in the game that can only be opened with this key. The areas you’ll have to visit are spread all around the game world, so expect to do a whole lot of exploring.

Sniflheim – Whale Way Station	Finally, you should look in the northwestern corner of the map while flying to locate the Sniflheim – Whale Way Station.
