Witchcraft
Witchcraft can only be taken if the player choses a High Concept or an Aspect for their power.
Overcome: Witchcraft can be used to overcome obstacles, but it tends to be slower and less forceful in most situations. Think how natural forces might overcome an obstacle: like forcing a door because humidity causes it to warp. You could of course imagine a hurricane ripping it off its hinges, but this is a forceful way if no Hurricane is actually present on the scene...The TN serves as the stress needed in the scene, you can lower this amount by sticking close to the time needed for nature to do its work, each scene you wait after setting "Nature" in motion lowers the stress required of the scene by 1, paid on the actual moment when you get to the scene to overcome it. So you could set the door to warp and go do other scenes, and when you come back you can just push it open (after paying the actual cost).
The likelihood of the event naturally happening can also lower the stress, up to a minimum of 1. Getting the floor the weaken so you can fall through when the house is on fire would make it much easier... Or warping a door in a humid derelict building could cost as little as 1 stress.
