Willpower is the disciplined ability to stay focused, and not become distracted by the worlds attempt to grab attention, or your desires.

Characters with low Willpower are often easily swayed by means of persuasion, offers, sights, and material objects. The critical flaw is that a distracted person will drop what they are doing, and have difficulty returning to the situation at hand until they've satisfied their curiousity. High Willpower characters can do well by staying undistracted by cheap tricks, and keeping their party on the ball as well.
