Take the man as an example. Open the menu and press L 1 to enter the role properties. You can see three proficiency levels: fencing, air raid and flame strike. If these three skills are high, you can learn new moves.

Sword hitting high can learn ground skills, high hitting can learn air skills, and flame hitting high can learn the blade of flame.

Another is to click on the skill disk with sp when you get the new title. Eight banners air knife, not taking the usual way, made a U-shape when making a move, but it seems that you can change the move by pushing a lottery when you are in the middle of the move, and the action is not neat enough. I'd better just keep a dragon.
