"Miracle"

People are desperate, and miracles bring them hope.
You can make something strange that is interpreted by the other people as a miracle, or you can twist and interpret things and events in a way that makes people believe they saw a miracle. Everyone wants to see a miracle.
Perhaps it is some kind of weird and unusual mutation, a colorful display of willpower and meditation, some weird act of stage magic, some uncanny psychological cleverness, or perhaps it is actually something truly supernatural, that lets you impress the rest of the people, and consider you a holy man or woman.
Whenever you have the chance to do your thing, roll Will + Control, against Smarts & Control of the smartest person in your audience.
If you succeed, you get an extra +2 to all your further Persuade, Deceit, and Seduction rolls against all the people of your audience, for a year.
