Eevee can be evolved into eight different Eeveelutions with different main skills in Pokemon Sleep. Read on for a tier list of the best Eeveelutions, the best Eeveelution skills, and how to get each Eeveelution.

Best Eeveelutions Tier List for Pokemon Sleep

Eeveelution Main Skills and Overall Tier List

Pokemon	Skill	Tier
Sylveon	Energy for Everyone S
Jolteon	Extra Helpful S
Flareon	Cooking Power-Up S
Espeon	Charge Strength M
Glaceon	Cooking Power-Up S
Vaporeon	Ingredient Magnet S
Umbreon	Moonlight (Charge Energy S)
Leafeon	Energizing Cheer S

All Eeveelutions (Eevee's evolutions) are Skills Specialty Pokemon that share the same ingredients but have different Berries due to their differing types as well as different main skills.

Sylveon is the best Eeveelution on our tier list because of its ability to keep your helper Pokemon energized. It works best if the other helper Pokemon you have on your team pick up a lot of items in a short span of time.

Jolteon, Flareon, Espeon, and Glaceon are all very good Eeveelutions as well, but they're at the B-tier because there are other Pokemon that do similar jobs but slightly better. Flareon and Glaceon's Cooking Power-Up S can be especially powerful if you have a team full of Ingredient Specialty Pokemon.

Leafeon's Energizing Cheer S isn't as consistent as Sylveon's Energy for Everyone S, putting it in the C-tier. Vaporeon and Umbreon both have main skills that aren't exclusive to Skills Specialty Pokemon, so you have less reason to use them.

Best Eeveelution Sub Skills and Natures

Best Sub Skills for Eeveelutions

The best sub skills to have for all Eeveelutions are those that boost main skill chance and main skill level. This allows your Pokemon to utilize their strong main skills to their full potential.

Other good sub skills to have are the gold-colored ones such as Sleep EXP Bonus or Research EXP Bonus, but these aren't really necessary.

Best Natures: Main Skill Chance Up

As Skills Specialty Pokemon, the best Natures for all Eeveelutions are those that increase main skill chance. However, the Calm Nature isn't recommended because it reduces a Pokemon's speed of help, making it a less effective helper Pokemon.

All Eeveelutions can be found in various research islands, all at high Snorlax Ratings. These Pokemon are rare, but if you want to register their Sleep Styles to your Sleep Style Dex, you will have to find them after your sleep sessions. Evolving Eevee is not enough to add them to your Area Dex or Sleep Style Dex.

List of All Research Areas

Evolve Eevee

Pokemon	Type	Evolution Requirement
Vaporeon		・ Water Stone ・Eevee Candy x80
Jolteon		・ Thunder Stone ・Eevee Candy x80
Flareon		・ Fire Stone ・Eevee Candy x80
Espeon		・Log 150 hrs of sleep with Eevee, then evolve it during daytime ・Eevee Candy x80

Leafeon		・ Leaf Stone ・Eevee Candy x80
Glaceon		・ Ice Stone ・Eevee Candy x80
Sylveon		・Log 150 hrs of sleep with Eevee ・Eevee Candy x80

Although you can catch these Pokemon in the wild, it's easier to obtain Eevee's evolutions by evolving Eevee, since Eevee is a much more common Pokemon.

Eeveelutions also perform better when evolved. Evolving a Pokemon increases the level of their Main Skill by 1, which is very valuable to these Skills Specialty Pokemon.
