Okay so im not understanding till, sorry, But how do i get these wings?
First, you acquire a formula that has the word Inizio in its name. It'll be a level-1 formula.
When you complete that formula you recieve a level-2 formula.
When you complete
that formula you recieve a level-3 formula.
And so on, through a series of thirteen formulas that get increasingly harder to complete.
Each Backwings quest actually has three different sets of wings you can recieve, but the small wings and medium wings are just pit stops on the path. You have to use those wings as components in the next formula. They're just opportunities to stop if you don't think you can handle going further.
