More Enchantments

We all know that shields have only 2 or 3 enchantments. I think that they should have more. My ideas are below:

• Super Shield: When hit with a weapon (sword, axe, bow, crossbow, trident), if you are shielding, it acts as thorns to return the damage without being hurt.

• Shield Thrower: Starting at 4 block range (going up 1 block for each enchantment level), if you are crouching (shielding), then attack your shield will fly out of your hand, disabling your opponent from taking it, and if it hits, it does 2 hearts of damage (goes up half a heart for each enchantment level). Highest enchantment level is 4.

• Healing Shield: If you have below half of your hearts, you can shield and heal yourself, BUT it takes durability away from it (25 per heart).

These next two things are just random ideas I had while making this.

• I think you should be able to shield surf by standing on top of a hill or water, jumping and then rapidly crouching while in the air, then control with however you move on your version of Minecraft (stay crouched or it won't work)

• Sniper: This enchantment is for bow or crossbow where your arrow flies straight (basically defying gravity) and goes farther before coming down doing 2 extra hearts of damage. Level 2 makes it if you do hit the ground close to your target it will create a shockwave that does 2 hearts of damage. If it hits it does 5 extra hearts of damage. Maximum enchantment level is 2.
