A Pokemon game is not complete without Eevee, the bushy-tailed fave among Pokemon Sun and Moon players.
Eevee is one of the most popular Pokemon in the series because of its unassuming appearance and many evolutions with different elements, including the water-type Vaporeon, lightning-type Jolteon, psychic-type Espeon, fire-type Flareon, fairy-type Sylveon, ice-type Glaceon and grass-type Leafeon. While there are no new Eevee evolutions, required conditions, and materials to evolve it have been changed.
How to Evolve Eevee into Vaporeon, Jolteon, Espeon, Falreon, Sylveon, Glaceon and Leafeon
To evolve Eevee into Jolteon, you should give it a special stone called Thunder Stone, which you can get by going to the back of the caravan at the Fossil Restoration Center on Route 8. You can also get it through minigames at Poke Pelago or purchase it in Konikoni City for 3,000 credits.
To evolve it into Vaporeon, you need to expose Eevee to a Water Stone which you can find in Route 8 in the water south of the small island. You can also buy it in Konikoni City for 3,000 credits or win it at Poke Pelago.
In the same way, you can also evolve Eevee into Flareon with a Fire Stone which you can win at Poke Pelago or buy for 3,000 credits. You can receive a freebie at Diglett's Tunnel in the northwest corner with a Tauros as well.
Meanwhile, to evolve Eevee into Espeon, you have to raise Eevee's friendship level to about 220 by giving it different vitamins and Berries, winning several battles without it fainting and having it hold a Soothe Bell. You can also increase its happiness quickly through a trick where you need to grab two TM items which Eevee can learn and teach it moves over and over again. The Pokemon feels happier every time it learns one. After that, you can make it gain a level during daytime to evolve it into Espeon.
To evolve Eevee into Umbreon, you have to follow similar steps as evolving to Espeon, but this time, the level should be raised at night.
To evolve Eevee into Sylveon, it has to learn a Fairy-type move and head to Pokemon Refresh through the menu. You have to earn two hearts by petting it and feeding it Poke Beans. It will evolve when it levels up.
Meanwhile, you can evolve Eevee into Leafeon by having it in your party and going to the Lush Jungle near Route 8. There is a big rock which should say the surface is covered with moss, it feels soft to the touch. Just keep on fighting the Pokemon in the area until it evolves into Leafeon.
Lastly, to evolve it to Glaceon, you need to follow the same instructions to evolve Leafeon, but this time, you'll need an icy rock which could be found at the Pokemon League. It should say it is a rock that is covered in ice, touching it is likely to freeze you solid!
