Here's the situation, to put into context the question. My character in the game (which we are running troupe style) is a battered, abused and bitchy street goth with Ghost Speaker Power. She 4 Stunts as well, most of them reflecting her sarcastic attitude and her streetwise vibe.
Her Trouble is that a faerie lady has put a very potent curse on her - she is rapidly aging backwards, diminishing from her twenties into her teens, and at current writing six years old in body. This is part of the character's natural progression - she is learning to trust, to love and forgive and forget by being forced to be helpless and be helped. It's all good drama.
What our group has discussed is that this character, when she bounces (there's a plot planned for this), will end up with the potential to become a Wizard. Already the ghost of a wizard has taught her Channelling, which is planned to slowly overtake her Ghost Speaker power, and eventually she will become a full Wizard (if she makes the right choices). But she's left with these 4 Stunts which are making less and less sense. To make the conversation topical, the four Stunts are Hairpin Maestro, Resilient Self-Image, Takes One to Know One, and Infuriate.
I want to remove some or all of these Stunts. But according to the system, you can only swap Stunts. Is there no means to evolve a character such to remove Stunts as the character progresses? We are, of course, totally willing to just ignore the system to suit our game. But for the purposes of interest, is it possible to carve Stunts back for Refresh and / or Powers?
