Some ideas / Enchantments

I was seeing about the nerf to Blast and Fire prot and how Mojang reversed it and buff these the enchantments, so I think we can do that with more enchantments and made them better! There are my ideas:

• Projectile prot: Now when you wear one or more armor with this enchantment you can have a probability to reflect projectiles, more armor and higher level equals more probability
• Knockback: It's annoying when you try to do a combo having a Knockback sword, so why not make the enchantment only work when you do a knockback attack?
• Bane of Arthropods: I know the enchantment give the arthropod slowness, but i think we can do more! Now they can't hurt you when they have slowness, and you have a little chance that they'll become afraid of you and start running away from you, higher level equals higher probability
• Smite: Now when you attack undead mobs they'll get slowness or weakness

There're others ideas:

• Frost walk: Is usually useful, but I think a really good addition would be increment the friction when the user is walking in ice
• To turtle shield: These are really good, but I have a new exclusive function, now when wear a Turtle shell with aqua affinity will increment your underwater vision, and wear it with respiration increment the Water Breathing effect time

• Curse of fragility: Reduce the tool/armor/object durability
• XP Miner: increment how many xp you get (incompatible with fortune)
• Boost (to Elytras): Now you can propel yourself twice in the air, like with fireworks; it consume xp
