I'm planning a Misfits-style game using the rules from Kerberos Club Fate. I'm trying to figure out the best way to model a character whose power is the ability to drastically enhance other people's powers. I want this to work by actually increasing the power level of another power temporarily, but I'm not sure of the best way to model this as a skill. Would it just be a couple of Unusual modifiers?
Ryan has the skill "Laser Eyes" at a +2 Supernatural level. May has the "Enhance Power" skill. When May uses it and focuses on Ryan, she raises his skill based on how well she rolls. If she rolls poorly, she could raise it to a +3 or +4 as long as he uses it. If she rolls well, she could raise it to Ascendent or even Godlike levels.
Having it work only as she's focusing is easy enough. But other than aspects and fate points, I can't figure out how to enhance others.
