You've finally decided to upgrade. That diamond pickaxe is fine, sure, but it’s not Netherite. If you’re asking where can i find ancient debris, you’re likely tired of your tools melting in lava or just want that sleek, dark flex on your armor stand. It's a grind. Honestly, it’s one of the most tedious things you can do in Minecraft, but the payoff is literally indestructible gear.
Ancient Debris doesn't behave like coal or iron. You won’t find it sitting pretty in a cave wall while you're out exploring. It’s buried. Deep. And it’s rare enough that you could mine for twenty minutes and come up with absolutely nothing if your strategy is off. This isn't just about luck; it’s about understanding the specific generation logic that Mojang baked into the Nether’s code.
The Science of Spawn Rates
Let’s get the math out of the way first. Ancient Debris generates in two distinct "batches" per chunk. The first batch attempts to generate one vein of 1–3 blocks from levels 8 to 22. The second batch tries to generate another vein of 1–2 blocks across levels 8 to 119.
Statistically, level 15 is your sweet spot.
Why 15? Because that's where the frequency of those two batches overlaps most consistently. If you go too high, you’re only betting on that second, much thinner batch. If you go too low, you’re swimming in lava lakes. Level 15 (your Y-coordinate) puts you just above the massive lava seas that dominate the bottom of the Nether, giving you a solid floor to work with.

The Best Way to Actually Find It
Strip mining is for the Overworld. In the Nether, if you just hold down left-click with a pickaxe, you’re going to burn through your durability and your patience. You need explosions.
TNT vs. Beds
Beds are the "budget" meta. Since beds explode in the Nether with a higher power than TNT (a power level of 5 compared to TNT’s 4), they are incredibly effective at clearing out massive amounts of Netherrack. Netherrack has very low blast resistance. Ancient Debris, however, is blast-resistant. It literally cannot be destroyed by explosions. When everything else turns to dust, the Debris stays floating there.
But beds are annoying. They don’t stack. Your inventory gets cluttered with wool and wood, and you have to constantly craft more. If you have a gunpowder farm and a sand source, TNT is the superior choice. You can stack 64 of them, place them in a long line with two blocks of space between each, and trigger a chain reaction that reveals a massive tunnel in seconds.
The "Poke" Method
If you're low on resources, try the branch mining technique but with a twist. Dig a long 2x2 tunnel. Every five blocks, poke a hole into the walls as far as your reach allows. This increases your "visual" range without requiring you to mine every single block. It's slower, but it saves your gear.

Myths and Misconceptions
People think you can find Ancient Debris exposed to the air. You can't. Well, technically, the game can try to generate it there, but the code explicitly checks if the block is adjacent to air. If it is, the Debris often won't spawn. This is why you almost never see it on the side of a cliff or in an open cavern. It wants to be "hidden."
Another weird thing? It’s not just in the "Wastes." You can find it in any Nether biome. Soul Sand Valleys are actually decent because the visibility is higher once you clear the fog, though dealing with Ghasts and Skeletons while you're trying to mine is a nightmare. Warped Forests are safer. No Endermen will bother you if you don't look at them, and there are no Creepers or Ghasts to blow you up while you're focused on the Y-level.
The Gear You Need Before You Go
Don't go in with an iron pickaxe. You literally can't mine it. You need Diamond or Netherite to actually drop the item.
- Fire Resistance Potions: These aren't optional. If you hit a lava pocket—and you will—while bed-mining, you're dead without a potion.
- Blast Protection Armor: If you’re using the bed method, the "intentional game design" explosion will hurt. A lot.
- Efficiency II+ Diamond Pick: You want to slice through Netherrack like butter.
- F3 Screen (Java Edition): Keep an eye on that Y-coordinate. If you’re at Y: 30, you’re wasting your time.
Smelting and Crafting
Once you find the stuff, you’re only halfway there. You get "Netherite Scraps" from smelting the debris in a furnace or blast furnace. To make a single Netherite Ingot, you need four scraps and four gold ingots.

This is where players get stuck. They find two pieces of debris and think they're ready to upgrade. Nope. You need four blocks of debris just for one tool.
Actionable Strategy for Your Next Session
To maximize your efficiency right now, follow this exact sequence. First, head to the Nether and dig down to Y: 15. Ensure you have at least two stacks of TNT or 20-30 beds. Dig a straight tunnel for about 100 blocks.
If using TNT, place one every three blocks. Back up, ignite, and wait for the lag to settle. Walk through the new cavern. Look for a block that looks like a brownish, swirly log. That’s your target. If using beds, place a block between you and the bed before you "sleep" to minimize the damage you take.
Don't forget to check the floor and ceiling of the blast zone. Ancient Debris often hides just behind a single layer of charred Netherrack.
Once you’ve collected at least 16 pieces of Ancient Debris, head back to your base. This will give you enough for a full set of tools or armor. Combine the resulting Scraps with Gold, and use a Smithing Table—not a Crafting Table—to apply the Ingot to your Diamond gear. This preserves your enchantments, which is the whole point of the upgrade anyway.
