* Level: Most Pokémon evolve at specific levels.
* Held item: Some Pokémon require specific items to evolve, such as a Shiny Stone or a Dusk Stone.
* Friendship: Certain Pokémon evolve based on their friendship level with the player. This can be increased by using them in battles, giving them berries, and generally taking good care of them.
* Location: Some Pokémon evolve only in specific locations or environments.
* Time of day: Some evolutions are triggered by the time of day, such as evolving during the night.
To help your partner evolve:
1. Train them: Level them up through battles and exploration.
2. Give them the right item: If their evolution requires a specific item, make sure they are holding it.
3. Increase their friendship: Spend time with your partner, give them berries, and avoid letting them faint in battle.
4. Explore the right locations: Some Pokémon evolve only in certain areas.
5. Be patient: Evolution can take time, depending on the Pokémon.
Important Note: Your partner will not evolve even if they reach their evolution level if the other requirements are not met.
Remember: While you can't directly control your partner's evolution, you can create the conditions that will allow them to evolve naturally.
