Add just one block, with which you can test your luck, just break the block, instead of it, blocks, mobs or traps may appear.
After installing the mod, lucky blocks will be randomly generated in three forms: without structure, in structures made of quartz blocks, and in structures made of hell-stone. The block of luck in quartz structures have luck from +50 to +100. A luck block in hell-stone structures has a luck of −50 to −100. Without structure, ordinary lacquer blocks appear.
