Question: what level does eevee evolve into sylveon in pokemon ultra moon?
Answer: Feed it beans as well. You'll need to get the affection level to two hearts for Eevee to evolve. You may need to battle with Eevee for a bit before you can make this happen. Once the Eevee's affection is at two hearts, battle and level up to get it to evolve into Sylveon.
