Certain characters can manipulate the Force to create special effects. These characters have a Force Rating, a number of points that they can spend to use Force powers, to reroll any die roll (even a natural 1 on an attack), or to move 2 extra squares as part of a move. Once a Force point is spent, the character can’t spend it again during the skirmish.
A character can spend Force points only once per turn. Sometimes, though, a character can spend Force points on other characters’ turns, such as to reroll a failed save. In this case, a character can end up spending Force points more than once per round.
