Minecraft Hardcore is a very challenging game mode. This mode is the most difficult and popular among Java Edition players.
Farms can make Minecraft much simpler. This is especially important for Hardcore gamers. It's useful to have everything automated in a game mode that sees death as the final word.
Automatic smelting plants are extremely useful for ores that produce raw materials (copper and iron, respectively). You can create one using hoppers, furnaces, chests, and furnaces. It can be as large as you like. This removes XP from smelting but speeds up the process. This is very useful for Hardcore players as they can concentrate on other tasks rather than smelting.
Sugar cane farms are extremely useful in any game mode. Sugar cane is useful for making books, sugaring or trading with librarians. An automatic sugarcane farm is a great way to obtain it, especially in Hardcore mode. To make them, players need to have pistons, observers, and dispensers (for Bonemeal).
This is a tricky one as it can be hard to get a sheep in a small space. It's possible to make wool from it once it's done. This is a very useful product.
Although it takes longer as the wool must grow back, it is much quicker than manually doing it. It's great for crafting and trading. Instead of worrying about collecting wool, hardcore players should focus on keeping alive.
A hostile mob is one of the most common ways to die. It's best to avoid them entirely, at least in Hardcore mode. They do however give up valuable loot if they are killed.
