Get to Friendship Level 10

After befriending nine of the same species of Pokemon, your Friendship level with that Pokemon will be at Friendship level 10. This level can only be seen during Snack Time after conducting sleep research.

Friendship level 10 guarantees the next Pokemon of that species you befriend to have a gold Sub Skill as their first Sub Skill.

Unfortunately, this does not affect Pokemon that you have already befriended. This only affects Pokemon you recruit from Friendship level 10 onwards.
