Ancient debris refers to a rare block found in the game Minecraft. It is primarily used to craft netherite, a powerful material that enhances tools and armor. Players can find ancient debris deep underground, typically between levels 8 and 22 in the Nether dimension. To obtain ancient debris, players must mine it using a diamond or netherite pickaxe. Once mined, it can be smelted in a furnace to produce netherite scrap. Four scraps, combined with a gold ingot, create one netherite ingot, which is essential for upgrading equipment and improving durability in the game.
