New type of attack & anti-mace enchantment

We have only 5 types of attacks right now - sweeping attack, weak attack, strong attack, knockback attack and critical attacks. As 1.21 is a lot of Combat, why not a new type of attack? I have a idea, when a critical attack is hit on the chest area of a mob or a player, it would do a stab attack. This attack would stun all the weapons and tools of the player for 2 seconds. Cool no? Changes can be made accordingly. Now for the second one, we have Mace. Mace is overwhelmingly strong and Breach has put Protection enchantments to shame but armours can no longer withstand this. An anti-mace enchantment can be added to reduce the damage significantly. It would only be found in ominous vaults.
