Gold blocks now have another purpose. The lucky block can be crafted using 4 gold ingots and a dropper, and of course you can discover it in the natural open world.
A warning from it’s creator: If luck is not on your side, this block may have devastating effects on you or your world. It is recommended that you backup your world, use a not important world or go hardcore and take the risk.
