Ancient Debris is a resource in Minecraft that you can only find in the Nether. Ancient Debris is highly sought after, as it can give you Netherite, which can be used to upgrade Diamon armor, weapons, and items. Ancient Debris tends to spawn the most between levels 8 and 22 of the Nether but has been known to randomly spawn at other levels.
Ancient Debris will spawn as a mineral vein, just like other ores in the game, but you will need to be careful when trying to mine it. Ancient Debris will only drop if the vein is mined with a Diamond or Netherite Pickaxe. If you mine the vein with any other tool, nothing will drop. Ancient Debris can also be found in chests in Bastion Remnants. Bastion Remnants are castles that can be found in the Nether and are home to the Piglins.
You can find Bastion Remnants in the following biomes:
- Crimson Forest
- Nether Wastes
- Soul Sand Valley
- Warped Forest
Chests found in the Bastion Remnants can spawn a minimal amount of Ancient Debris, normally just one or two pieces. Mining for Ancient Debris is considered to be the best way to go about finding it, due to higher yields and the quick break time of the Netherack stone that it tends to spawn in.
Ancient Debris can be smelted in a furnace or blast furnace to make Netherite Scrap, and the Netherite Scrap can be combined with Gold to create a Netherite Ingot. You need four pieces of Netherite Scrap and four Golden Ingots to create a single Netherite Ingot.
