In Pokémon Legends: Arceus, evolving Roselia is a straightforward process. You will need a special item called a Shiny Stone. Once you have a Shiny Stone, you can use it on your Roselia to evolve it into the beautiful and powerful Roserade.

Finding a Shiny Stone

So, where can you find this essential item? There are a couple of reliable methods for obtaining a Shiny Stone in the Hisui region. The most common way is by collecting Merit Points. You earn these points by returning lost satchels you find scattered throughout the world. Once you have accumulated enough Merit Points, you can head over to the Trading Post in Jubilife Village and exchange them for a Shiny Stone.

I remember when I was trying to evolve my own Roselia. I spent a good chunk of my playtime just exploring the Crimson Mirelands, not just for the story, but specifically to find lost satchels. It took a little while, but the satisfaction of finally getting that Shiny Stone and seeing my Roselia evolve was totally worth it. The second Roserade became a staple in my party for the rest of my journey.

Another way to get a Shiny Stone is through space-time distortions. These are random events that can occur in any of the game's areas. Inside these distortions, you have a chance of finding rare items on the ground, including evolutionary stones like the Shiny Stone. I’ve had a few lucky encounters where I've stumbled into a distortion and found exactly what I needed. It's always a thrill because you never know what you're going to get!

Once you have your Shiny Stone, simply open your satchel, select the stone, and use it on your Roselia. The evolution animation will begin, and you'll have a brand new Roserade to add to your team.
