On page 113, it described how gaining or losing something within the fiction can result in addition or removal of something in your playbook, even without taking an advancement. It then gives an example about Skysong crashing her ship into a giant opponent, destroying said craft and the GM telling her player to “mark it off” her playbook. Does “marking it off” mean unchecking the box for the move/extra, therefore making it available to regain via an advancement? Or is it crossed out entirely, requiring her to regain a “Kirby Craft” like vessel within the fiction? (The same way she lost it.)
