Shield Enchantment: Absorbency I, II, III

This is a shield enchantment which lessens fall damage. With Absorbency on a shield, holding up the shield while falling will equip the shield at an angle more towards the ground. Upon impact, you will bounce until your momentum is gone, taking reduced fall damage compared to falling the same height without the shield. The bouncing would be less like falling onto a slime block, and more like falling onto a bed. Just an idea. I know there are similarities with Feather Falling.

Maybe as an added unique feature of this enchantment, having a shield enchanted with Absorbency in your main or off-hand while flying with an elytra will greatly reduce damage taken from "experiencing inertia".
