If this work highly contributes to your one, please consider giving me credit, thank you!
There are plenty of works out there about flying and falling damage, but not a single one about slow fall.
So here is one.
Reinhardt's shield works like a parachute.
I tried to make it realistic, so the effect will be significant only if you hold the shield-parachute lifelike.
