A weapon for players with the playstyle of avoiding mobs in the new caves

I was thinking of a weapon with an AOE type of attack that pushes mobs away. It can be the horn from minecraft dungeons since we have goat horns now.

This weapon will have a cooldown and has a pretty huge range (like 7 to 12 blocks radius). This will only be found in the chests in the deep dark and will be pretty rare.

It could also be obtained via enchantments to the goat horn since minecraft dungeons has many uses for horns like healing and etc which may not yet make it to this update if it ever gets added.

To avoid players from spamming it, there should also be a negative effect to the player everytime they use it like knockback to the opposite direction that they are looking at or a slow effect for a short while as an indication of exhaustion from blowing the horn.

This will not only be useful in the caves but also for the other dimensions like in the nether. (Magma Cubes are hard to deal with in a nether highway)
