we’ve been collecting data and testing several Eevee-lution theories for the past few days. Today, we’ll be presenting the results of our research and explaining how Night/Day Eevee evolutions work.
Research Summary and Results
There are two ways to obtain Umbreon and Espeon: by using the one time name trick or by evolving your Eevee under special circumstances. The latter can be used multiple times with the same result, unlike the Sakura/Tamao naming trick.
You can evolve any number of Eevees into Umbreon and Espeon, if they satisfy the following criteria:
- The Eevee must have 10 KMs walked and 2 Candy collected as your Buddy
- The Eevee must be set as your current Buddy during evolution
- Evolving such Eevee at night will yield Umbreon DARK
- Evolving such Eevee during day will yield Espeon PSYCHIC
How this research was conducted
Fortunately, the GO Hub has access to two very engaged and active player communities: our local community in Split (Croatia) and the global readership community, with a special shoutout to readers and researchers from Leipzig, Germany.
During the past 3 days, we’ve managed to get 23 Eevees up to 10KM of walked distance as Poké Buddies. Our initial hypothesis was that in order to obtain Umbreon or Espeon, you need to increase your “friendship” level with an Eevee.
Remembering how “shoulder Buddy Pikachu” was based on collected Candy and not actual distance, we made sure to keep 3 of those Eevees with 10KMs walked and only 1 Candy collected.
Here’s the result of our testing:
|Time of day||Walked 10KM||Collected 2 Candy||Buddy while evolving||Repeated||Result|
|Targeting Umbreon evolution||Night||Yes||Yes||Yes||5||5xUmbreon|
|Targeting Espeon evolution||Day||Yes||Yes||Yes||7||7xEspeon|
|Testing Candy requirement Umbreon||Night||Yes||No||Yes||1||Jolteon|
|Testing Candy requirement Espeon||Day||Yes||No||Yes||2||Flareon|
|Testing “Set as Buddy” criteria Umbreon||Night||Yes||Yes||No||2||Flareon
|Testing “Set as Buddy” criteria Espeon||Day||Yes||Yes||No||4||Jolteon
|Testing chance of random evolution||Day||No||No||No||6||2xJolteon
After observing the results, we’re glad to report that Niantic did transfer the “Friendship” aspect from the core series when evolving Eevee.
Although we did not manage to evolve Eevee randomly into Umbreon or Espeon, it is still too early to say it’s impossible. This research was solely focused on properly understanding Umbreon and Espeon evolution mechanics and requirements with Buddy distance, Candy and time of day.
