In real life, it's usually easier to brace when falling then jump... so you can fall down from higher then you can jump up....
With the Force Power Tree : Enhance... with Force Jump, could you use that force power to cancel out the effects of falling damage ? I mean, if your force enhanced legs are strong enough to push you up in the air to "medium range", then they sould be strong enough to absorb the impact of the fall.
Maybe make a Athletics check to make sure your characters knows how to brace for a fall and a Force Jump check to see if he's force enhanced. I'm not sure how it would play out mechanically, but I think you could reduce falling damage with Force Jump.
What do you guys think ?
