The Battle of the Department of Mysteries Brilliant Event Part 1 functioned in two ways: first and foremost, as a storytelling event. Harry Potter: Wizards Unite succeeds or fails based on how much players pay attention to the quest dialogue, as this is, unlike Niantic’s bigger hit Pokémon GO, a narrative game. It’s easy to jump in at any point, but the actions of the game truly only make sense once the game is understood as a sequel to the Harry Potter books. Beyond the story, this Brilliant Event was essentially a collection game. The idea is to complete the Event page in the Registry by collecting the required amount of Brilliant Foundables to complete their images. For example, five Brilliant Ron Weasley must be found, or his spot in the Registry will be incomplete.
