The best Y level to find Ancient Debris is Y=15. This is where Ancient Debris spawns most frequently in the Nether. Mining at this level gives you the highest chance of finding this rare ore, which you need to craft Netherite gear.
That said, Ancient Debris can spawn anywhere between Y=8 and Y=119, so understanding how it generates helps you mine more efficiently.
Ancient Debris Spawn Rates by Y Level
Ancient Debris doesn't spawn evenly throughout the Nether. Here's how distribution works:
Primary Spawn Zone (Y=8 to Y=22)
- Y=15 has the highest concentration
- 1-3 blocks spawn per chunk in this zone
- This is where you should focus your mining
Secondary Spawn Zone (Y=8 to Y=119)
- Additional 1-2 blocks can spawn anywhere in this range
- Much lower density than the primary zone
- Not worth specifically targeting
The Sweet Spot
Most experienced players mine between Y=13 and Y=15. This range catches the peak spawn rate while keeping you above the worst lava lakes that sit around Y=10.
How to Check Your Y Level
Press F3 on Java Edition to open the debug screen. Your Y coordinate shows your current height.
On Bedrock Edition, enable "Show Coordinates" in your world settings. Your Y position displays in the top-left corner.
Best Mining Methods for Ancient Debris
Ancient Debris is blast-resistant, which makes explosive mining extremely effective. Here are the most popular methods:
Bed Mining (Most Popular)
Beds explode when you try to use them in the Nether. This is the cheapest and most efficient method.
How to do it:
- Mine at Y=15
- Dig a tunnel 1 block wide, 2 blocks tall
- Every 4-5 blocks, dig a small alcove to the side
- Place a bed at the end of the alcove
- Stand back and right-click the bed
- The explosion clears out a large area instantly
Why it works: The explosion radius is large enough to expose Ancient Debris while the debris itself survives the blast.
TNT Mining
TNT works similarly to beds but costs gunpowder and sand.
How to do it:
- Mine at Y=15
- Place TNT every few blocks along your tunnel
- Ignite with flint and steel or redstone
- Collect exposed Ancient Debris
Pros: Faster than beds if you have lots of TNT Cons: More expensive to craft
Strip Mining
The traditional method—slower but requires no special resources.
How to do it:
- Mine at Y=15
- Dig a long 1x2 tunnel
- Every 2 blocks, dig side tunnels to increase coverage
Pros: Safe, no explosion damage risk Cons: Takes much longer than explosive methods
How Much Ancient Debris Do You Need?
To fully upgrade one piece of diamond gear to Netherite:
- 4 Ancient Debris = 4 Netherite Scraps
- 4 Netherite Scraps + 4 Gold Ingots = 1 Netherite Ingot
- 1 Netherite Ingot = 1 upgraded piece
For a full set of Netherite armor plus tools:
- Helmet: 4 debris
- Chestplate: 4 debris
- Leggings: 4 debris
- Boots: 4 debris
- Sword: 4 debris
- Pickaxe: 4 debris
- Axe: 4 debris
- Shovel: 4 debris
- Hoe: 4 debris
Total: 36 Ancient Debris for everything
That sounds like a lot, but efficient bed mining at Y=15 can get you a full set in an hour or two.
Ancient Debris vs Other Nether Ores
| Ore | Best Y Level | Rarity |
|---|---|---|
| Ancient Debris | Y=15 | Very rare (1-5 per chunk) |
| Nether Gold Ore | Y=10-117 | Common |
| Nether Quartz | Y=10-117 | Very common |
Ancient Debris is by far the rarest ore in Minecraft, which is why Netherite gear is so valuable.

Frequently Asked Questions
What Y level is best for Ancient Debris?
Y=15 is the optimal level for finding Ancient Debris. This is where the ore spawns most frequently in the Nether.
Can Ancient Debris spawn at any Y level?
Ancient Debris can technically spawn between Y=8 and Y=119, but the vast majority spawns between Y=8 and Y=22, with Y=15 being the peak.
How rare is Ancient Debris?
Very rare. Only 1-5 blocks of Ancient Debris generate per chunk on average, making it the rarest ore in Minecraft.
What's the fastest way to find Ancient Debris?
Bed mining at Y=15 is the fastest method. Beds explode in the Nether and clear large areas quickly while Ancient Debris survives the blast.
Can you mine Ancient Debris with an iron pickaxe?
No, you need a diamond or Netherite pickaxe to mine Ancient Debris. Lower-tier pickaxes will break the block without dropping it.
How many Ancient Debris do I need for full Netherite?
You need 36 Ancient Debris total for a complete set of Netherite armor (16 debris) and all tools (20 debris).
Does Fortune work on Ancient Debris?
No, Fortune does not increase Ancient Debris drops. Each block always drops exactly one Ancient Debris regardless of enchantments.
Is Ancient Debris blast proof?
Yes, Ancient Debris is blast-resistant and won't be destroyed by explosions. This is why bed mining and TNT mining work so well—the explosions clear away other blocks but leave the debris intact.
