Crafting recipes (3 ways you can craft this block)
Some blocks that are dropped may have uses
Mining bows can deal damage to mobs and mine blocks but aernt effected by looting/fortune enchantment
Throwable spawn eggs use these to distract your opponent
There are also other throwables like throwable diamonds and silverfish grenades)
There a decoration blocks that look like my other lucky blocks (navy/electronic/metal/aoe/spooky/frosty) but they don't do anything but used for crafting
this block may spawn fake cursed lucky blocks which fortunately can be used for crafting
