In my story, there's a cliff. An icy one, with snow and ice below it, on the side of a mountain. It's a pathway that's probably about 1.5 to 2 meters wide, and snow is covering ice patches on the path. I'm really bad with heights but I'm talking a large cliff, though the size can be altered to fit what I need to happen.
The whole scenario is:
Character A is walking ahead of Character B when he suddenly slips and tumbles over the edge. B grabs him but is pulled over as well, due to the ice and his crappy shoes. He rolls in the air so that his back takes the brunt of the impact, with A against his chest. They both need to live, but there's some pretty advanced magic at their rescue, so that shouldn't be too much of an issue. Also, A is very sturdy and is prone to jumping from as high as three stories and walking away without a scratch. The cliff, therefore, should be more than 3 stories.
How much damage would Character A sustain? And what about Character B? What kind of injuries would be created from this fall? And how tall is a tall cliff, anyways?
