How to Evolve Cosmoem

Disclaimer: Pokedex.me is an unofficial fan-site and is not affiliated with Nintendo or Game Freak.

To evolve Cosmoem in the mainline games, you must level it up to 53. The evolution process is entirely dictated by the specific game version you are playing, bypassing any player input, held items, or in-game time mechanics.

If you play Pokémon Sun, Ultra Sun, Sword, or Scarlet, hitting level 53 transforms Cosmoem into the Steel/Psychic-type Solgaleo. Conversely, playing Pokémon Moon, Ultra Moon, Shield, or Violet results in the Ghost/Psychic-type Lunala.

• Solgaleo versions: Sun, Ultra Sun, Sword, Scarlet.
• Lunala versions: Moon, Ultra Moon, Shield, Violet.

If you want the opposite Legendary for your Pokédex, you must trade your Cosmoem to a player with the alternate version. They must level it to 53 in their game to trigger the specific evolution, and then trade the evolved Pokémon back to you.

Niantic's mobile game abandons version exclusivity for a time-based mechanic. Evolving Cosmoem in Pokémon GO costs 100 Cosmog Candies, assuming you have already spent 25 candies to evolve Cosmog into Cosmoem.

The evolution outcome depends strictly on the local time in your game application. Pressing the evolve button during the daytime yields Solgaleo. Triggering the evolution at night guarantees Lunala.

Always check the in-game sky before spending your candies. The visual day or night state on the overworld map screen overrides any real-world clock discrepancies, ensuring you get the exact Legendary you target.

Verdict: 8.5/10. Solgaleo operates as a premier bulky physical wallbreaker and sweeper in restricted competitive formats. Its Steel/Psychic typing provides nine resistances and total immunity to Poison-type attacks.

The Full Metal Body ability prevents opponents from lowering its stats, rendering common Intimidate users completely ineffective upon switch-in. Sunsteel Strike, its signature move, delivers massive STAB damage while ignoring defensive abilities like Disguise or Unaware.

• Pros: Excellent defensive typing, immune to stat drops, reliable heavy physical damage.
• Cons: Weak to common Ground (Earthquake) and Dark (Knock Off) attacks. Lacks reliable recovery outside of weather-dependent Morning Sun.

Who it is for: Players needing a sturdy physical pivot that can absorb resisted hits and maintain offensive pressure. Who should avoid it: Teams already severely weak to Ground or Ghost types that cannot cover Solgaleo's blind spots.

Verdict: 8/10. Lunala functions as a devastating special sweeper, leveraging a massive base 137 Special Attack stat. Its signature ability, Shadow Shield, halves all incoming damage when Lunala is at maximum HP.

This ability acts as an upgraded Multiscale, allowing Lunala to survive almost any single non-STAB attack to retaliate or set up a Calm Mind. Moongeist Beam delivers consistent Ghost-type damage while ignoring opposing abilities.

• Pros: Phenomenal ability guarantees setup opportunities, massive special damage output, wide coverage movepool including Ice Beam and Meteor Beam.
• Cons: Debilitating 4x weaknesses to Ghost and Dark. A single Sucker Punch or Shadow Sneak can easily score an OHKO if Shadow Shield is broken.

Who it is for: Hyper-offense players who maintain strict hazard control to keep Shadow Shield intact upon entry. Who should avoid it: Teams lacking Defog or Rapid Spin support, as Stealth Rock completely breaks Lunala's defensive gimmick.

Reaching level 53 requires patience because Cosmoem possesses zero offensive capabilities. Its movepool consists entirely of Splash, Teleport, and Cosmic Power, meaning it cannot defeat opponents on its own.

In Generation 8 and 9, the fastest leveling method involves feeding Cosmoem EXP Candies L and XL. You can farm these candies efficiently by clearing 5-star and 6-star Max Raid Battles or Tera Raids. This item-based method bypasses the need for combat entirely.

In Generation 7, you must rely on passive experience gain. Keep Cosmoem in your party with the EXP Share turned on. Farm the Elite Four to siphon experience points, or use Rare Candies for the final, most tedious levels between 45 and 53.
