Pokémon Legends: Arceus – The Sea’s Legend Guide

Manaphy in Pokemon Legends Arceus.

Key Takeaway

To progress through Request #66: The Sea's Legend, you'll need a hint from Pokémon Brilliant Diamond or Pokémon Shining Pearl. After following this hint, explore the Cobalt Coastlands with specific Pokémon in your party during the evening. This unlocks the area where Manaphy and Phione spawn.

It’s pretty tricky to catch Manaphy in Pokémon Legends: Arceus unless you’ve read a hint in another game. And, even after you do, you’ll have to meet some specific criteria before you can find this legendary Pokémon.

    How to Progress Through Request #66: The Sea’s Legend

    A player reading about The Sea's Legend in Pokémon Brilliant Diamond and Shining Pearl.

    The details you get about this request in Pokémon Legends: Arceus are very sparse. This is because the steps for completing it are actually in another game. You’ll need to play Pokémon Brilliant Diamond or Pokémon Shining Pearl to find these steps.

    You’ll need to go to Canalave Library and head up to the second floor. In the bottom right of the second floor, there is a row of four light-yellow bookcases. On the second one from the left, you’ll find a book titled “The Sea’s Legend.” The text of this book tells you exactly how to progress through the request of the same name in Pokémon Legends: Arceus.

    The Sea’s Legend’s Text

    There are only a few lines of text in this book, however, all of it is important. Here’s what the book says, word for word:

    One upon a time in the East Sea, there was a Pokémon known as the prince.

    A brave human asked Pokémon living in the sea to let them see the prince.

    Mantyke, Buizel, and a Qwilfish with huge spikes acknowledged the human’s bravery and joined them.

    Together, they set off in a boat over the sunset-streaked sea, sailing through the ocean gate stretched over the waves.

    News of this reached the ears of the prince, who went to meet the brave little party at the Seaside Hollow.

    What the Text in The Sea’s Legend Means

    The first line of the text mentions the East Sea, which is a reference to the Cobalt Coastlands. Next, the mentioned three Pokémon living in the sea are required to progress the request. You’ll need a Mantyke, a Buizel, and an Overqwil (a Qwilfish with huge spikes) in your party.

    When you have those three Pokémon, you’ll need to sail through the “ocean gate” at “sunset.” The ocean gate is the formation of two pointy sea stacks that lies to the north of the ‘middle finger’ of the Sand’s Reach area in the Cobalt Coastlands. You’ll need to head here during the evening, as that’s when sunset happens.

    Afterward, you’ll get a message when you go between the two sea stacks at the ocean gate. This message says that you heard a cry in the distance and that a boulder has shifted. This indicates that the Seaside Hollow has been opened.

    However, if you’ve already done the request to catch Giratina in the Seaside Hollow, this text will seem a bit odd due to the Seaside Hollow already being open. Regardless, now’s the time to head there in search of Manaphy and Phione.

    Be sure to head there with Pokémon that can help you battle and catch Water-type targets, as there will be a group of four you’ll need to confront.

    How to Catch All the Required Pokémon

    Locations where you can catch Buizel, Mantyke, and Qwilfish.

    All three of the Pokémon you need to trigger the event at the ocean gate can be found in the Cobalt Coastlands. Firstly, Buizel can be found in the Aipom’s Hill and Bather’s Lagoon areas. Next, Mantyke can be found in the Ginkgo’s Landing and Tranquility Cove areas.

    Lastly, you can find Qwilfish in the Tranquility Cove, Lunker’s Lair, and Islespy Shore areas. However, don’t forget that you need to evolve Qwilfish into Overqwil to meet the criteria for triggering the ocean gate event. To do so, you’ll need to get your Qwilfish to use Barb Barrage 20 times in Strong Style.

    The Location of the Seaside Hollow Where You Can Catch Manaphy

    The location of the Seaside Hollow in the Cobalt Coastlands.

    The Seaside Hollow can only be accessed from the northern waters of the Cobalt Coastlands. Ride Basculegion almost all the way to Islespy Shore while looking south. Soon, you’ll find the subtle entrance that leads into the Seaside Hollow.

    When you enter the cave, you’ll have to watch a short cutscene that shows you there are three Phione and one Manaphy in the cave. Get ready for a rumble, as they will all begin to attack you the moment the cutscene ends.

    You can’t use stealth here, however, you can run around and dodge the incoming attacks. By doing so, you can separate the four Water-type Pokémon and take them down individually or in pairs.

    How to Catch Manaphy

    The player's Torterra using Sleep Powder on an enemy Pokémon.

    The Phione and Manaphy in the Seaside Hollow will mostly use Water-type attacks. However, they also have access to Fairy and Psychic-type damage-dealing moves—so be wary. They can also use Acid Armor, which will let them take a fair deal more damage.

    As mentioned before, a great tactic is separate the quartet by dodging and running around. When you’ve forced your foes apart enough that some aren’t focused on you anymore, engage the closest targets in battle.

    The Phione are all at level 35 and the Manaphy is at level 50, so show up with party members higher than these levels for an easier battle. Typical tactics to improve catch rate success are effective here, so use your preferred method.

    If you’re not sure how to approach these legendary Pokémon, use a bulky Grass-type that knows a sleep-inducing move. For example, a Torterra with Sleep Powder is a decent choice.

    Whittle down the HP of your targets until it’s in the yellow or red zone before inflicting them with a status condition. This condition doesn’t have to be sleep, as paralysis works just as well. Poison, burn, and freeze are equally effective (in terms of catch rate modifiers), although there’s a risk that the damage they inflict over time can knock out your target.

    How to Complete the Request After You Catch Manaphy

    After you catch Manaphy (and hopefully Phione, as well), head to Professor Laventon to complete Request #66. When you do, Laventon will have some dialogue about Manaphy and will give you three Comet Shards—which you can sell for $15,000 each.
