Whenever you are in someone’s Secret Base, you are able to take their flag, in a simplified version of the Underground quests in Pokémon Diamond/Pearl: however, unlike then, you simply have the flag once taken.
You can take a flag once per day from any base. You can also earn flags from your Secret Pals, but what do flags even do?
As you earn enough flags from the various bases, you can speak with Aarune in the Fortree Secret Base Guild to rank up. This comes with a number of rewards, too, as below:
