Lucky Block Mod is a really simple mod, but really fun (and at the same time scary) to play with, and will most likely appease all gamblers out there. The mod features the Lucky Block, which looks kinda like a coin block from the Super Mario Bros. game franchise.
Break the block and receive a gift which you don’t know what it is until you receive it. This is why the mod is so fun to play with. What you will receive will be picked randomly from 100 different items and effects, from gold, weapons, coal, diamonds (and even wishing wells) to annoying harmful effects. Or an angry Ender Dragon. Pretty much like a game of dice, only that you have a 100-sided dice.
You can craft the Lucky Block using the following recipes. Do note that you can continue upgrading the quality and amount of items found in the block by continue crafting it using more gold ingots until you get a +100 Lucky Block.
As I said, this mod is a really simple one, so there’s not much left to talk about it. Let’s skip to the installation.
