Some monsters, supernatural entities, powers or vehicles are so powerful that they possess a “Power Factor” noted PF(X).
This is a bonus that grants automatic successes on certain tests, equal to the number in brackets. For example, a superhero capable of transforming into a living flame or a flamethrower tank benefits from a PF(4) for anything related to flames.
When he makes a test, he automatically benefits from 4 successes before even rolling the dice. The Power Factor also increases weapon damage, protection, and the character’s or vehicle’s Power Factor by the same amount.
