Question: pokemon x and y what level does eevee evolve into sylveon?
Answer: Does Eevee evolve into Sylveon at level 20, or does it just it evolve when Eevee hits the next level? It evolves when it reaches any new level, as long as it knows a Fairy-type move and has at least two hearts of affection in Pokemon-Aime. You need an Eevee and need 2-3 affection.
