First, and easiest to implement, as GM you could simply disallow the defensive roll to reduce impact damage in extreme cases. Falling from the roof of a warehouse? Go ahead and roll to take the damage to your legs instead of your head. Falling from the roof of the Chrysler Building? Forget it. No amount of wriggling is going to keep your skull intact.

For more detail, you could use the following modified rule. This is a suggested modification, not an official revision. If you use it, replace the text under this subheading as follows.

Reducing Impact Damage (page 40)
Some skills and miracles help reduce impact damage. If you see it coming you get a single dice-pool roll with a relevant stat+skill or superpower (at the GM’s discretion) as a defense against the damage.

If the impact is a surprise—you don’t see it until the round when it’s going to hit—you must have Coordination dice equal to or greater than the damage to see it coming. See the impact chart for dice equivalents.

The impact defense roll has to be declared in a combat round—you can’t just freely scrap something else you’re rolling to reduce impact damage. Some relevant stats and skills include Body+Endurance, Body+Jumping and Coordination+Acrobatics.

A successful roll has two benefits.

First, you can transfer the defense roll’s width in damage from hit location 10 to one other hit location. This is useful because you can choose to suffer some of the damage on your strongest or most armored hit location.

Second, if you’re falling and you land on your feet (or equivalent limbs), subtract your jumping distance (as determined by your Body stat) from your yards-per-round speed to determine how much damage you take. If your jumping distance is greater than your speed, you suffer no damage at all—not even the 2 Shock per location.

Example: Mafia goons throw Leatherneck out of a helicopter high over the city. Ordinarily he would take 2 Shock to each hit location and 7 Killing to the head in falling damage at terminal velocity. But with a Coordination+Parachuting roll at width 5 he transfers 5 of the Killing damage to his torso. He takes 2 Shock and 1 Killing to the head, 2 Shock and 5 Killing to the torso, and 2 Shock to every other hit location. After Leatherneck hits pavement he has a body full of broken bones but, incredibly, can get up and stagger away.
