Netherite Upgrade Guide: Debris to Smithing Template

What upgrading to netherite actually costs you

Most netherite guides stop at the recipe list. This one starts from the number that matters: how many ancient debris you have to mine for the gear you want.

The chain is short and every link has a fixed ratio. One ancient debris smelts into one netherite scrap (plus 2 experience points). Four scrap and four gold ingots craft into one netherite ingot — a shapeless recipe, so slot order does not matter. One ingot plus one netherite upgrade smithing template upgrades one piece of diamond gear. Multiply it out and the debris requirement is simply 4 blocks per ingot.

The full set figure of 10 ingots is the wiki's own number for all netherite tools and armour together. Ten ingots means 40 ancient debris blocks and 40 gold ingots, plus ten templates. That is a very different planning figure from "a few netherite ingots", and it is the reason most players upgrade gear one piece at a time instead of planning a full set.

Gold is the hidden bottleneck as often as debris is. Forty gold ingots is more than most players carry, which is why the classic move is to barter with piglins for gold — or to carry gold nuggets rather than netherrack while mining, so your inventory is not clogged with the wrong material when you find a vein.

Step 1: mining ancient debris without dying

Ancient debris is a rare ore that generates in the Nether as scatter ores, which are never naturally exposed to air. It can only replace netherrack, and in Java Edition also basalt and blackstone. On average Y = 16 carries the most debris; the common generation band is Y 8–24 in Java and Y 8–23 in Bedrock, with an additional Java cluster spread as high as Y 119.

Java rolls up to two clusters per chunk: a primary cluster of 0–3 debris attempts distributed triangularly from Y 8 to 24, plus a secondary cluster of 0–2 attempts spread evenly from Y 8 to 119. Bedrock is more generous — up to five clusters per chunk. A single vein holds at most 3 blocks unless two veins happen to sit close enough to merge, which is why you should always tunnel around every block you find rather than assuming a vein is finished.

Ancient debris has hardness 30 and blast resistance 1,200 — by far the toughest thing in the Nether. It also has two properties that decide your method: it floats on lava, and in item form it is completely immune to fire. Lava does not destroy it, and neither does falling into a lava ocean.

Because of that blast resistance, one TNT will not break debris. The trick is to chain explosions: blow the netherrack underneath, let the falling block expose the next one, and repeat. Beds are the cheap version of the same trick — beds explode in the Nether and cost a fraction of TNT. The wiki is explicit that the high blast resistance of debris, paired with the very low blast resistance of netherrack, is exactly what makes explosives profitable here.

One warning that applies to every method: do not let the wither break ancient debris, and never dig the block you are standing on.

Step 2: the tool that actually matters is the one you already own

Ancient debris has hardness 30 and drops nothing unless mined with a diamond or netherite pickaxe. The mining times show what the tier buys you:

Read that last row carefully, because it is the trap. A netherite pickaxe is only 13% faster than a diamond one on debris. Meanwhile a wooden pickaxe is 13 times slower and drops nothing at all. The upgrade from diamond to netherite is a luxury; the upgrade from wood to diamond is what makes the resource obtainable.

So the gearing order matters: get a diamond pickaxe first, mine debris, make one netherite pickaxe, and only then is the second pickaxe worth the extra 13%.

Step 3: bastions give you both the template and the shortcut

The netherite upgrade template is found only in bastion remnant chests, and so are ancient debris and netherite scrap. This is the part most guides miss: the template and the material come from the same place, and the chest odds are worth knowing before you commit to a bastion run.

Bedrock Edition differs: the hoglin stable chest drops one debris at 5.7%, the generic chest at 13.5% and the treasure chest at 11.3%. The wiki also records that in 1.16.2 the chance of finding netherite ingots in bastion chests was raised from 16.8% to 42.1% — the treasure room of a bastion is a genuinely good target.

Chest loot and mined debris solve the same problem from opposite ends: chests give you the template you cannot make, and mining gives you the debris you cannot reliably loot.

Step 4: the template you can copy, and the ingot you cannot

Templates are the one netherite component you can farm. A netherite upgrade template plus 7 diamonds and 1 netherrack copies itself into 2 templates — the netherrack is consumed, the diamonds are consumed, the original template is returned. Each run of that recipe nets you one extra template.

For a full set you need ten templates, so nine copies plus the original: 9 × 7 = 63 diamonds and 9 netherrack. That is a real diamond bill, and it is the reason the first two bastions are worth clearing properly — you should find several templates in one trip rather than one at a time.

The ingot has no such shortcut. Four scrap plus four gold ingots is the only route, and it is a shapeless recipe, so the four scrap and four gold can go anywhere in the grid. One netherite ingot then upgrades one piece of diamond gear at a smithing table, keeping durability, enchantments, your custom name, trim and prior work penalty intact.

Smithing upgrades cost no experience and do not raise the prior work penalty, unlike an anvil. That difference is why the smithing table is the right station for this job and not merely a convenient one.

What upgrading preserves — and what it costs you

The upgrade keeps the enchantments, the prior work penalty, the trim and the number of durability points already lost (not the remaining durability). It also grants netherite's own traits: netherite gear is fire and lava resistant in item form, and netherite blocks are effectively explosion-proof.

Against that, netherite gear is slower than diamond in the hand — roughly 30% slower to swing — and it is heavy. The trade is durability and protection for speed, and the correct answer depends on whether you are mining, fighting, or building.

One more modern note: since 1.20, a netherite ingot can also be used as an armour trim material. That is a separate recipe from the upgrade path, and it does not need a template — but it does consume an ingot you could otherwise have used for gear.
