Critical Hit Enchantment: Increasing Critical Hit Damage

The Critical Hit enchantment would increase the weapon's critical hit damage per level. This would be compatible with all Sharpness related enchantments so players wouldn't have to be forced to choose between a sword that's enchanted with Sharpness or a sword with Critical Hit but can't have Sharpness related enchantments applied to it. One last thing that would make this enchantment even more unique is whenever the player would land a critical hit, the weapon would then glow then slowly fade away.
