Legendary titans Regirock, Regice, and Registeel can be recruited to your rescue team in Pokemon Mystery Dungeon DX for Nintendo Switch. Here's everything you need to know.
Mystery Dungeon DX released for the Switch on March 6, bringing Nintendo and The Pokemon Company's 2005 Game Boy Advance titles – Red and Blue Rescue Team – to the modern day with a new painterly-esque art style and mechanics such as Auto-Move and Mega Evolution.
Something that's reappeared, though, is the ability to recruit Legendary monsters to your team. Regice, Registeel, and Regirock are just three that can join you, and we've got all the details on how to do so below.
How to recruit Regirock, Regice, and Registeel
As with all Legendary Pokemon, you can't recruit the Regi trio to your squad until you finish the main campaign. Once that's done, you'll need to befriend Kyogre in the Stormy Sea – the guide for which can be found here.
After you've beaten the dungeon, you'll receive a letter in the mail a few days later telling you about the Buried Relic and the possibility of rare monsters residing there. Once you've spoken to Lombre and Shiftry, it'll open up and you'll be able to explore it.
On floor 15 of the cave, you'll find Regirock who you must defeat to pass. You can't recruit him yet, and instead you must progress through to 25F and then 35F where Regice and Registeel will be waiting to fight you – but still won't join your team.
Once you've cleared the Buried Relic, you need to make sure you've bought the Ancient Relic camp from Wigglytuff for 700 CP otherwise the trio won't join you.
Take on the dungeon again, and upon reaching all three floors the monsters are on, you'll be able to recruit the Legendary titans to your rescue squad after a second defeat.
You'll notice that they all drop a piece of Music Box – the item that's used to summon Mew. You can find out how to find him from here in our guide.
