Describe the bug
The energy storage of quantum armor is not used at all to protect the user against damage. While the +20 base damage is obviously very strong, this still makes the user quite vulnerable in certain situations, like falling in lava or being swarmed by many mobs. If this is an intentional choice, then given the cost of making the quantum armor, as well as how it's behaved in IC2, where the energy would discharge against damage so that you effectively wouldn't take damage as long as it was charged, then a change should be made in my opinion.

Steps to Reproduce
Charge and wear quantum armor.

Environment (please complete the following information with the version):

• Minecraft: 1.16.4
• Mod Loader: Fabric

Additional context
I was just testing the armor in survival mode, and I found it rather shocking that literally 3-5 creepers in hard mode can kill you while you're wearing quantum armor with prot IV enchantments on all of them. Given how expensive it is to make, the energy should be the thing discharging instead of the health if the user were to take damage.
