From time to time, a new Brilliant Event will appear in Harry Potter: Wizards Unite. These events affect the gameplay significantly. During them, you can face new enemies, collect new resources and rewards.
What are Brilliant Events about?
During a Brilliant Event, your goal is to complete a task given by the developers. Players can also get new objects. These tasks aren't difficult - they usually are about traveling a certain distance, or doing a certain action a few times, e.g. fighting enemies.
How long a Brilliant Event lasts?
These events last a certain amount of time. You can check this information right after a Brilliant Event starts.
What can I get?
During this event, you can get items for another register. These objects appear only during Brilliant Events. You can also get new resources, runestones, and money.
However, the most important rewards are Restricted Section Books - you need them to develop your character. Currently, these books can't be acquired in any other way.
