Here is everything you need to know about how to obtain Manaphy and Phione in the Cobalt Coastlands area.

 

The Legend of the Seas

To obtain Manaphy and Phione in Pokémon Legends: Arceus, you must have received side request 66, titled "The Legend of the Seas".

 

The Arch of the Cobalt Coastlands

You will be able to catch them in the Cobalt Coastlands area, but be careful: before that, you must have met these conditions: 

 

 

Once that is done, head to the Cobalt Coastlands, more precisely near the rocky arch at Sand’s Reach when the sun sets. Walk through the arch to hear Manaphy’s cry echo. If you heard it, rush into the cave at Seaside Hollow (next to Veilstone Cape) to meet Manaphy with 3 Phione at its side. Break their shields to fight them and catch them! 

 

 

 

Once you have caught them, go back to Professor Laventon to make your report and complete the request.
