Onyx, a throwable item in the deep dark (The Wild Update)

as of right now snowballs can be found from chests in deep dark cities, but why would snowballs be in the deep dark, shouldn't there be another item better suited for the deep dark?

I think that a new mineral should be introduced in The Wild Update, my idea is to add Onyx, I think that this mineral would fit so well into the deep dark and it could be used in the same way as snowballs, a throwable item that can cause audio decoys to distract the warden.

Onyx could also be used as a new decorative item, when you combine 4 onyx together you can create an onyx block that is Really Shiny :D 

Onyx can be found in chests or mined from Onyx clusters, similar to Amythist clusters but much smaller and more common to find, but they only generate in the deep dark.
