Sylveon, Glaceon, and Leafeon
**Updated 6 months ago**
To obtain the newest of the Eevee evolutions, first make your Eevee very happy via the Pokemon-Amie system. All three sections in Amie (Affection, Fullness, and Enjoyment) must be maxed, so be ready to play a ton of minigames to have enough snacks. Once done, simply teach your Eevee a fairy move and level up to have it evolve into Sylveon!
As for evolving a Glaceon or Leafeon, you must be standing next to Ice Rock or Moss Rock when leveling it up. Ice Rock is found in the deepest part of the Frost Cavern (the cave is not too large) while Moss Rock is found closer to the end the quest to defeat the Elite Four. It is on Route 20, between Snowbelle City and the Pokemon Village. Enter the area from Snowbelle to immediately see it.
