Ralts is a Psychic and Fairy-Type Pokémon in Pokémon Brilliant Diamond/Shining Pearl that can evolve into Kirlia once certain conditions are met. Trainers can find Ralts within five spawn locations in Pokémon BDSP: Stargleam Cavern, Fountainspring Cave, Dazzling Cave, Route 203, and Route 204. The Stargleam, Fountainspring, and Dazzling caves are located within the Grand Underground zone. To unlock this area, players must reach Eterna City and speak to the Underground Man near the town’s Pokémon Center. He will provide the player an Explorer’s Kit, which grants access to the Grand Underground. Conversely, players will need the post-game PokéRadar to find Ralts on Route 203 or 204.
How to Evolve Ralts in Pokémon BDSP
Once players have caught Ralts in Pokémon Brilliant Diamond/Shining Pearl, they can evolve it into Kirlia by having the Pokémon attain Level 20. Kirlia can further evolve into Gardevoir or Gallade after reaching Level 30. Trainers can only obtain Gallade by giving a male Kirlia a Dawn Stone, a rare item found on Route 212, Route 225, and Mt. Coronet.
Acquiring the PokéRadar to encounter Ralts on Route 203 or 204 will require quite some effort, as players must first complete their Sinnoh Dex to receive the National Dex from Professor Oak. Once the upgrade has been obtained, Trainers can meet the professor again at Ramanas Park, where he will grant the PokéRadar.
Reaching Level 20 to evolve Ralts in Pokémon BDSP is relatively easy, especially when the Pokémon is equipped with a Lucky Egg. This special item will increase the XP gained from battles by 1.5×, allowing its holder to level up quickly. Lucky Eggs can be bought from the Battle Tower for 77× BP, or they can be found in the world, like in Acuity Lakefront within the Grand Underground.
Pokémon Brilliant Diamond/Shining Pearl are available on Nintendo Switch.
