Sylveon, the fairy-type Eevee evolution, has finally been added to Pokémon Go, and just like its predecessors, it has special evolution requirements.
There are two methods to evolve your Eevee into a Sylveon. The first is using a simple renaming technique. If you rename your Eevee to “Kira,” it will evolve into a Sylveon with no other specifications needing to be done. It costs 25 Eevee Candy to evolve it. This Eevee naming trick can only be done once, so once you get your Sylveon named Kira, you won’t be able to use this strategy again.
The second method takes a bit longer, and it involves setting Eevee as your buddy Pokémon. Make the Eevee you want to evolve into Sylveon your buddy, and earn 70 hearts with it. You can only earn around 12 hearts a day with your buddy (by feeding it berries, walking with it, battling with Eevee, etc.), so this will take around six days to evolve your Eevee. However, you can earn more hearts per day by feeding your buddy a Poffin. Once you earn these hearts, it will cost the usual 25 Eevee Candy to evolve it.
You can tell if you did either of these techniques correctly because the shadowed silhouette on the Eevee’s evolve button will show a Sylveon, rather than a question mark. If you see a question mark, you may have done something incorrectly.
Sylveon went live on May 25 at 10 a.m. local time, so make sure you don’t try to evolve your Eevee before then.
