As one would expect, players can brew potions in Wizards Unite.
Each potion has a specific effect and can be brewed using items gathered in Green Houses. The brewing of potion has a delay before being ready. This delay can be reduced if you can crack the code for each specific potion, called Master Notes. Master Notes consist of gestures to be applied over the cauldron while the potion is being brewed. After using a set of Master Notes for a potion three times, the game will remember the set for you.
Below are the various possible Master Notes/gestures.
