This datapack adds 5 custom lucky blocks to the game.

First, drop an iron ingot onto a placed crafting table, that will give you the lucky block crafter.
Next, put a wooden pickaxe into the crafter, it will enchant it with Luck I, a new custom enchantment.
When mining coal with this Luck I pickaxe, there is a chance that you will get a lucky ore.
Mine this lucky ore with an iron pickaxe or higher to obtain the luck essence item. I- f you craft this in the lucky block crafter in a cross shape, with the luck essence in the middle and coal around the outside you will get a coal lucky block.
Place this down and break to get a random item.
Sometimes you will get a stone pickaxe enchanted with Luck II.
Mine iron with this, and you can get more lucky ore, which drops a different kind of luck essence, which, when crafted in the same way as before but with iron ingots instead will give you an iron lucky block.
