Item: Adamant Orb Event: Dialga Capture Opportunity |
In the Fallshore Mission HQ, after completing 20 Missions and receiving Type: Null, a researcher will ask you to travel to the Cave of Being. The goal is to capture the Lake Trio of Uxie, Mesprit, and Azelf. She’ll give you the Adamant Orb for this. In addition, you’ll be able to capture Dialga.
Starting the Mission
The Mission HQ is on the west side of Fallshore City just north of the Marketplace.

In order to receive this mission, you need to have become Pokémon Champion and already completed 20 other missions.
You’ll also need to have picked up the reward for that from the Pokémon Ranger near the inside doorway of Mission HQ, which is a Type: Null.

Go upstairs and into the apartment – there’s a researcher near the bookshelf you need to speak to. She’ll tell you to go to the Cave of Being on Route 10.

How to Complete
The easiest way to get to the Cave of Being is to go east from Tehl Town into Route 10.
From there, go north.


Keep going north, past the painter and the bridge, until you’re in a patch of long grass. Walk through it to the other side.

After you’re through the grass, continue north until you see a waterfall to the east.
Surf into the water and then ride the waterfall down to the lower section.

Once you’re there, surf south, between the cliff edge and the island in the waterway. You’ll come to a bridge – surf under it.

You’ll see a Rock Climb wall on the south side of the island – this is the path up to the Cave of Being.

After you’ve made it up the wall, head inside.
Once you’re in the cave, head north and you’ll see the researcher in the middle of a giant odd-shaped puddle.

Speak to the researcher, and she’ll direct you to go north and step into the middle of the odd puddle.
When you do, the cave will react, and three figures will appear.

Uxie, Mesprit, and Azelf – the Lake Trio – appear on the dry spots in the puddle. However, as soon as they assemble, they leave, flying off to different parts of Borrius.
The researcher then gives you some clues regarding their whereabouts.
- Uxie is knowledge, so will go somewhere there is a lot of knowledge or research going on
- Mesprit is emotion, so will go to a place where there was an emotional moment
- Azelf is willpower, so will go to a location with a lot of potential and determination to achieve something
Uxie
Based on the researcher’s clue, the prime place for research in Borrius is the Dream Research Lab, which is in Tarmigan Town.
Fly to Tarmigan Town and you’ll arrive in front of the Pokémon Center. From there, go to the town’s northwest corner.

As soon as you approach the Dream Research Lab, you’ll feel a presence. Say yes to check the surrounding area.

Uxie will appear, and you’ll get a chance to capture it.
Uxie, like the other members of the Lake Trio, is extremely difficult to catch and even Quick Balls don’t work very well. You may want to use a Timer Ball after a long battle for a near-guaranteed catch.

Mesprit
Fly to Frozen Heights and go northwest to the base entrance.

Head inside, and take the elevator down to B3F.


Zeph and his son will be here, but you don’t need to talk to them – just head inside a little and you’ll get a prompt to check the area.

When you do, you’ll see Mesprit in the middle of the hallway, ready for you to try and catch it.

Azelf
Fly to Victory Road and you’ll be on the upper part of Route 18.
From there, head north to the hill.


When you approach the hill, you’ll get asked to check the area.

Azelf will appear and you’ll have the opportunity to catch the final member of the Lake Trio.

Return to the Cave
Return to the Pokémon Center and use the PC to put all three of the Lake Trio in your party. Once that’s done, go back to the Cave of Being.
As soon as you enter the cave with the Trio in hand, they’ll return to their places in the puddle.
Then, in the middle of them, Dialga will appear.

Surprised that Dialga showed up, the researcher is pleased with your progress.

She’ll give you the Adamant Orb, and you’ll be able to try your luck at catching Dialga.
