Shield Enchantments

Shield don't have their own enchantments so what if they had enchantments that...

1. Reflected projectiles (such as arrows, fireballs, Etc.) farther and the higher level the enchantment is then the more precise it gets in the direction the player is facing.

2. When player is attacked while using shield it inflicts damage toward the attacker similar to thorns but on a shield.

3. When attacked with a melee weapon/fists or attacked by melee mobs it causes knockback and the higher enchantment level the farther knockback.

IDK I think this would be usefull. :)
