Want a graceful, psychic powerhouse on your team? Evolving Eevee into Espeon is a classic Pokémon goal! Here's the secret: Friendship, and Daylight.
First, you need to max out Eevee's friendship level. The best way to do this is by battling with it, feeding it berries, and generally keeping it happy. Avoid letting it faint! You can check its friendship level in most modern games using a specific character or item.
Crucially, Eevee needs to level up *during the daytime* with high friendship. That's the key! If you level it up at night, you'll get Umbreon instead. No elemental stones needed, just good old-fashioned bonding under the sun. Get ready to add this elegant Psychic-type to your roster!
