One of the main quest lines in Pokémon Sword and Shield: The Crown Tundra tasks you with examining ruins for traces of the Legendary Titans. This line is easily the best in The Crown Tundra, as it really encourages you to explore the new area while also forcing you to do a tiny bit of puzzle-solving. Not all of these creatures are required for the story as, much like with the Swords of Justice, there’s a secret encounter at the end of this quest line that’s easily missable for a number of reasons. Whether you need help getting through the quest tasks, or are just looking for the secret encounter, this guide will show you how to catch the Legendary Titans in The Crown Tundra, nabbing Registeel, Regirock, Regice, Regieleki or Regidrago, and Regigigas.
One quick note regarding the Legendary Titans in The Crown Tundra: Unlike most Legendary Pokémon, you can fight these until you capture them, since they’re required to beat the story. If you lose in battle, run away, or accidentally kill these creatures, all you’ll need to do is reset the light pattern on their respective floor to initiate the fight again. This is also handy advice for shiny hunters, as each encounter provides a new chance for the Titan to be shiny.
The first temple you’re likely to come across houses the Steel Titan, Registeel. This temple can be found right outside of Freezington in Giant’s Bed. Despite the ease with which you can find the temple, it’s also easily the most confusing to open.
Upon interacting with the door, you’ll be greeted with the message, “Let ring the piercing note that will wake the giant of steel.” You may be tempted to do something with the Bronzong hanging out in front of the temple, but this is a red herring. The actual solution is simply to whistle, by clicking the left stick. Yes, you read that right. Whistling. One of those features you likely haven’t used in so long that you forgot it exists.
In any case, once you whistle, the door to the temple opens. Once you enter, you’ll notice a fairly empty room with some dots on the floor and a statue along the back wall. To wake this Legendary Titan, simply walk across all the dots so that they light up, then interact with the statue to trigger the fight.
Deeper into Giant’s Bed, near the entrance to Giant’s Foot, you’ll find another temple, this time housing the Rock Titan, Regirock. The clue to get into the temple this time is, “Let the first Pokémon hold a never-changing stone.” If you’re familiar with evolutionary items, this description should ring a bell. Just like the clue says, you’ll need to have your lead Pokémon hold an Everstone, then interact with the door.
Like last time, light up all the lights on the floor, then interact with the statue to trigger the fight with Regirock.
The ruins housing the Ice Titan Regice are a bit harder to find. Head up Snowslide Slope as if you were going to the Crown Shrine. Along your path, you’ll come across a few buildings. Head behind the one on the left and follow the path under an archway to find yet another temple.
The temple door’s inscription reads, “Walk together with a living crystal of snow.” To meet this requirement, you’ll need to place a Cryogonal in the lead spot in your party, such that it follows you on the overworld. If you don’t have a Cryogonal already, there are a few wandering about in the area near the temple, so don’t worry too much about grabbing one.
Upon opening the door, enter the temple. Light up the floor once again, then interact with the statue to fight Regice.
Regieleki / Regidrago
Whereas the prior ruins have all housed a single Legendary Titan, the last temple houses two. However, as tends to be the case with Pokémon, you’re only allowed to encounter one of these in a given save. To find the temple, head through Roaring Sea Caves to the entrance of Frigid Sea. Get in the water, then head to the pathway on the right. Follow this until you reach the temple.
In order to open the door here, follow this clue: “A giant of rock. A giant of ice. A giant of steel. When gather the three giants, the door of destiny shall be opened.” This is easily the simplest clue, requiring you to have Registeel, Regirock, and Regice in your party at the same time. Thus, this must be the last temple you complete.
Similarly to the other ruins in Pokémon Sword and Shield: The Crown Tundra, you’ll have to complete a light puzzle to fight one of the Titans, though it’s not as simple as hitting all the circles this time around. As you enter the temple, observe that the cutscene emphasizes the dot patterns along the frieze above the door. Also note that the X pattern is set against a yellow background, while the Y pattern is set against a purple background.
By now, you should know the drill. Light up the lights on the floor and interact with the statue. It’s here where you’ll need to make your decision on which Titan to catch. If you want to catch Regieleki, use the dots on the floor to recreate the X pattern. To do this, light up the diagonal paths, along with the horizontal path. On the other hand, if you want Regidrago, create the Y pattern using the upper diagonal paths and the middle vertical path. Make sure you leave the second dot from the top unmarked though, or else it won’t work. Use the provided pictures for reference.
Regardless of which you choose, when you interact with the statue, the game will inform you that once you proceed to fight the selected Titan, you can’t change to the other. This applies even if you end the fight by a means other than catching. If you’re certain about your choice, feel free to proceed. If not, change the pattern and repeat.
Once you catch either Regieleki or Regidrago, report back to Peony to clear the second of the three legends you’re supposed to be investigating.
Though Pokémon Sword and Shield: The Crown Tundra counts the quest line as complete after catching Regieleki or Regidrago, there’s one final step in getting all the Titans, and this one is pretty cool. It’s time to take on the Legendary Titans’ master, Regigigas. Before you start, you’ll need to have all five Titans in your party at the same time. Since you can’t catch both Regieleki and Regidrago in the same save, you’ll need to trade for the one you’re missing, if only for a little while. You’ll be fighting Regigigas, which is a Normal type, so for your sixth party slot, I’d recommend a strong Pokémon with some Fighting-type moves.
To find Regigigas, fly to the bottom of Snowslide Slope. Head a tiny ways into Giant’s Bed, and you should see an inactive Pokémon den surrounded by four rocks. If you interact with it without having all five Titans in your party, you’ll get the usual “There doesn’t seem to be anything in the den…” message. Doing so with the Titans in your party, however, will see the den suddenly roar to life. Enter the den when prompted to find yourself in a one-on-one Max Raid battle against Regigigas.
Go through the battle as normal. Note that since this is technically a Max Raid battle, you can’t catch Regigigas until after you defeat it, so don’t hold back with your attacks. Once you have a chance to capture Regigigas, feel free to use whatever ball you’d like to catch it, as this is a guaranteed catch. As such, I wouldn’t use something important like a Master Ball. Also note that you can reset this fight by losing or soft resetting to try and grab that ever-elusive shiny.
Though Regigigas isn’t included in The Crown Tundra Pokédex, and thus doesn’t count for completion, it’s guaranteed to be at level 100, which makes for a really great reward for acquiring all the Legendary Titans. Given that it’s a bit of a process due to not being able to capture both Regieleki and Regidrago in the same file, I’d say it’s certainly worth the effort.
