Legendary Pokémon from previous generations are available in Brilliant Diamond and Shining Pearl, with most able to be obtained in just one version of the game.
In order to find them, you'll need to head to Ramanas Park. However, there are a few prerequisites:
Which Slate do you need to find Registeel?
Ramanas Park is a vast area made up of several caves, in which a specific type of Slate is requested.
In order to unlock the three Titans, take the Discovery Slate to the Discovery Room and place it on the plinth. This is the first Slate available from the Receptionist.
Save your game before placing the Slate if you're looking for a specific Titan -- if the one you want doesn't appear, just reload your game and try again. This will save you valuable time hunting Mysterious Shards, which are quite rare.
Meeting Registeel, the Steel Titan
Capturing Registeel can be challenging. Here's what you need to know about the Iron Pokémon.
Shiny Registeel
Registeel's shiny version is very different from the base form, so you shouldn't miss it when choosing whether to reset or not.
Tips to make it easier to capture Registeel
Follow this advice to make catching Registeel easier:
- Use a Quick Ball at the very start of the encounter, and a Timer Ball if the battle lasts more than 10 rounds.
- Take a Pokémon with False Swipe to ensure you don't accidentally kill it.
- Take a Pokémon that can inflict Paralyze or Sleep.
- Pay attention to how much PP its moves have.
- Save your game right in front of it, before engaging.
Scizor is ideal for catching the Rock Titan due to its dual Steel / Bug types.
If you accidentally knock it out, you will need more Discovery Slates. Once you have captured it, you will not be able to re-summon it.
Additionally, upon exiting, an NPC will give you a Registeel Statue for your Secret Base.
