Mace Nerf and Enchantments

As much as I love the mace and its abilities, it could be slightly nerfed. My idea is that it could take increasing damage from attacking from higher up, and which would require combining multiple maces in an anvil to repair it. Alternatively, the Mending enchantment could be applied to it. A new enchantment that could work for the mace is Exploding, like in Dungeons. The impact would grow stronger after falling from higher up and deal extra damage to surrounding entities. The explosion may also launch the player a couple blocks back up, giving them a chance at another, weaker hit. Finally, a different enchantment that could have a similar but less overpowered effect is Gale, which would simply blow nearby entities away and launch the player into the air. Open to more ideas in the comments!
