One or both of your legs have suffered serious trauma. If one leg is lame, this Fault is worth four points and you walk with a noticeable limp. You permanently gain the hampered condition. For 8 points, both your legs are nearly crippled, running is impossible for you (you automatically fail Dash checks involving the use of your legs), and you must walk with assistance, e.g. a cane, braces, magic, or a wheelchair (if such resources/technology are available). If you are deprived of your assistance, you gain the prone condition and must be carried by an ally to move.
