One of the most popular things to do in any Pokemon game is to find an Eevee and evolve it. Since Eevee has so many different forms it can take, it's an easy team staple. Sylveon is the fairy-type evolution of Eevee and an easy way to take down dragons.
To get a Sylveon, you will need to do a bit of work, as it's not as simple as using a stone or a special location to evolve your Eevee. You will need to catch an Eevee and keep it in your party until you have a high friendship level. You can check your current friendship in Jubilife City.

You will also need to have your Eevee learn a fairy-type move. This process can be a bit frustrating as your Eevee can also evolve into Umbreon or Espeon with high friendship. The only way to guarantee a Sylveon is to teach it a Fairy-type move before it reaches this point.
The easiest way to do this is by getting your Eevee to level 18 and allowing it to learn baby-doll eyes.

I start my day by exploring Teyvat in Genshin Impact and end it after reorganizing my apartment in Final Fantasy XIV. I am a diehard fan of N64 era games and will forever feel betrayed that Megaman Legends didn't finish. Outside of gaming, I have spend my time collecting manga, collecting anime figures, and watching anime with my naked cat.
