The best Y level for Netherite (ancient debris) in Minecraft is Y=15 in the Nether.

Core facts

  • Ancient debris can generate roughly between Y=8 and Y=22 in the Nether, but its highest concentration is around Y=15.
  • This “sweet spot” works in both Java and Bedrock, though exact generation mechanics differ slightly.
  • Mining a tunnel with your feet at Y=14–15 lets you see debris in the floor, walls, and ceiling, maximizing how much you expose per block mined.

Why Y=15 is best

  • Going lower (like Y=8–10) runs you directly into the big lava oceans that sit around Y=10, which makes mining slow and dangerous.
  • Y=15 keeps you above most lava seas while still being in the densest band of ancient debris spawns, so you get strong efficiency without constant lava issues.

Quick practical tips

  • Aim to mine long horizontal tunnels with your feet at Y=15, or at Y=14 if you want to cover both Y=14 and Y=15 with one tunnel height.
  • Use fire resistance potions and blast methods (beds or TNT) if you want to clear large areas quickly, since explosions expose debris without destroying it.

TL;DR: If you’re wondering “what is the best y level for netherite” , set your Nether tunnel so your feet are at Y=15 and branch mine or blast mine from there for the fastest results.
