1. Visit Luminous Spring: First, you must venture to Luminous Spring, which is a location within the game. It's a hidden area that can be found by traveling to Mt. Faraway and looking under the bridge near the entrance.
2. Complete Requests: Once you reach Luminous Spring, you need to complete requests given to you by the friendly Pokemon residing there. These requests can vary from helping find lost items to defeating specific Pokemon.
3. Collect Rainbow Tickets: As you successfully complete requests, you will be rewarded with Rainbow Tickets. Continue fulfilling requests until you have obtained 5 Rainbow Tickets.
4. Exchange for Fire Stone: Return to the central point of Luminous Spring and speak to the Clefairy named "Joyful." By presenting her with the 5 Rainbow Tickets, Joyful will give you a Fire Stone in return.
5. Evolve Your Pokemon: Finally, you can use the Fire Stone to evolve a compatible Pokemon. Pokemon such as Eevee, Vulpix, or Magmar can be evolved using the Fire Stone. Simply open your inventory, select the Fire Stone, and then select the Pokemon you wish to evolve.
