Ruby in Deep Dark Cities

with the upcoming wild update next year, i would definitely like to see them bringing back the ruby gem, as a crafting recipe for the ruby staff, a unique loot inside a chest in the deep dark cities, just like elytra is in end cities and other unique items.

my idea with ruby staff is it should function like a bow or a crossbow that instead of consuming an arrow, should consume either your hunger or even your hearts as ammo, with that, there is a unique relationship for why ruby gem existed in the deep dark cities. souls.

another idea in mind is what it shoots in an enemy. crafting a ruby staff at an unenchanted state should shoot out damaging snowball-like ammo we can call "energy" dealing great damage similar to a crossbow. enchanting then a ruby staff, would provide a list of fun new energy types like fire energy, ice energy, or so on.

and lastly, other than just for crafting, ruby gem should function like the netherite bar, not as an upgrade, but a unique enchant-type mechanic that can be called as "life-steal", where dealing damage to enemy from a weapon, or being damaged with an armor infused with a ruby, should chip out a portion of enemies' health and add to your own health.
