What Unbreaking does in Minecraft
Every time you swing a sword, mine a block, or take a hit while wearing armor, the game subtracts a point of durability from that item. Run out of durability and the item breaks. Unbreaking changes the math: each time the game tries to subtract a durability point, there’s a chance it just skips it. The item still does the work. It just doesn’t pay for it.
That’s why a maxed-out tool with Unbreaking III feels like it lasts forever. You’re not getting more durability on the bar. You’re getting more uses out of the same bar.
Unbreaking shows up on almost every damageable item: pickaxes, axes, shovels, hoes, swords, bows, crossbows, tridents, shields, fishing rods, shears, flint and steel, elytra, every piece of armor, and newer additions like the brush and the mace. If it can break, Unbreaking can stretch its lifespan.
How to get Unbreaking
There are four reliable ways to put Unbreaking on a piece of gear.
- Enchanting table. Place the item, drop in lapis lazuli, and roll for the enchantment. With 15 bookshelves around the table you can hit level 30 enchantments, where Unbreaking III is more likely to appear.
- Villager librarian trades. Cure a few zombie villagers, get a discounted librarian, and trade emeralds for an Unbreaking III book.
- Loot chests. End cities, ancient cities, dungeons, mineshafts, stronghold libraries, and fortress chests all roll the enchanted book table, and Unbreaking shows up often.
- Fishing. With Luck of the Sea III on your rod, enchanted books appear more often, and Unbreaking sits in the loot pool.
Once you have a book, combine it with the item at an anvil. The anvil takes one use and some experience. If the item is already enchanted with something else, the costs stack, so it pays to get Unbreaking on early before the item is loaded with other enchantments.
Books vs. table rolls
If you’re choosing between rolling Unbreaking on the enchanting table or applying it from a book, books win for two reasons. You don’t lose the slot to something you didn’t want, and you can stockpile books for everything you craft later. The enchanting table is fine for a first set of gear when you have no books yet, but as soon as you’ve got a librarian or a fishing setup running, books are the cleaner path.
How the math works
Unbreaking does not give your item more durability points. It changes the odds that a durability point gets used at all. The formula depends on the item type, and tools and armor work differently.
Tools, weapons, and most other items
For anything that isn’t armor, the chance of taking a durability hit on a given use is 1 / (level + 1):
- Unbreaking I: 50% chance to take damage. Item lasts about 2x as long on average.
- Unbreaking II: 33% chance. Item lasts about 3x as long.
- Unbreaking III: 25% chance. Item lasts about 4x as long.
A diamond pickaxe has 1,561 durability. With Unbreaking III, it averages around 6,244 swings of useful work before breaking. Add Mending and you’re at a tool you’ll never replace unless you lose it in lava.
Armor
Armor uses a different formula because durability damage is tied to how much damage the armor absorbed. The chance of taking a durability hit is (60 + 40 / (level + 1))%:
- Unbreaking I: 80% chance to take damage. About 1.25x as durable.
- Unbreaking II: roughly 73% chance. About 1.36x as durable.
- Unbreaking III: 70% chance. About 1.43x as durable.
That’s a real gap. Unbreaking III on a sword roughly quadruples its lifespan. Unbreaking III on a chestplate only adds about 43%. The enchantment is still worth running on armor (especially netherite gear you’ve poured experience into), but don’t expect armor to last as long as your pickaxe does.
Items with quirky durability behavior
A few items behave oddly with Unbreaking. The trident uses different durability rules when thrown versus melee. The shield, when it blocks an attack, takes durability equal to the damage it absorbed, and Unbreaking applies to that roll. The mace, when used for a high-fall smash, can lose more durability on a single hit than a normal weapon, so Unbreaking III is especially valuable on a mace you’re using for big drops.
Best items to put Unbreaking on
If you’re rationing books, prioritize in this order:
- Elytra. Elytra durability is precious, and you can’t easily craft new ones. Unbreaking III plus Mending is the standard setup.
- Pickaxe. You’ll use it more than any other tool, especially a netherite pickaxe.
- Sword or trident, depending on your playstyle. Combat tools get used hard.
- Bow or crossbow. Both fire dozens of arrows in a single raid fight.
- Fishing rod, if you’re farming with one.
- Armor. Worth it eventually, but the boost is smaller per book.
Shears and flint and steel are also good candidates if you use them a lot. The hoe is fine to skip until late game.
Stacking with Mending
Mending is the natural partner to Unbreaking. Mending repairs the item with the experience orbs you pick up. Unbreaking slows the rate at which the item takes damage in the first place. Together, your gear can stay at full durability indefinitely as long as you’re killing mobs, mining ores, or trading with villagers.
There’s no trade-off between the two. They’re fully compatible. Always put both on anything you plan to keep long-term.
What plays nicely with Unbreaking
Curses don’t conflict with Unbreaking, so Curse of Vanishing or Curse of Binding on the same item is fine. Sharpness, Efficiency, Fortune, Silk Touch, Looting, Protection, Power, Punch, Infinity, Loyalty, Riptide, Channeling, Sweeping Edge, and Unbreaking itself all coexist happily.
The only real conflict to remember: Infinity and Mending can’t share a bow. Since Unbreaking and Mending are usually what you want, an Infinity bow trades away near-infinite repair. Most players go Mending on the bow now that arrows are cheap to mass-produce.
Java vs. Bedrock differences
Behavior is functionally the same on both editions. The probability formulas are identical, and the maximum level is III on both. Small differences come from how the editions handle enchanting tables and trades, not from how Unbreaking itself behaves. If you’ve internalized the math on one edition, it carries over to the other.
Common mistakes
The most expensive Unbreaking mistake: putting Unbreaking III on an item before you put your other expensive enchantments on. The anvil cost of combining a heavily enchanted item with a new book climbs fast, and “too expensive” is a real cap. The order matters. Combine books with other books first to get a single high-level book, then apply that combined book to the item in one move.
The second mistake: treating Unbreaking as a substitute for Mending. Unbreaking slows the bleed. Mending stops it. On gear you want forever, you need both. Unbreaking alone on an elytra still wears out, just slower.
The third: assuming armor benefits as much as tools. It doesn’t. Put Unbreaking on your armor eventually, but don’t burn your only Unbreaking III book on a chestplate when your pickaxe doesn’t have it yet.
Frequently asked questions
What is the max level of Unbreaking?
Unbreaking III is the highest level you can get legitimately. You can technically push past it with commands, but the formula keeps working with diminishing returns.
Does Unbreaking work on elytra?
Yes, and it’s one of the best items to put it on. Combined with Mending, an elytra at Unbreaking III essentially lasts forever.
Does Unbreaking work on shields?
Yes. Shields take durability based on the damage they block, and Unbreaking III gives the shield a 75% chance to skip the durability hit each time. Very worth it for long fights or pillager raids.
Can you put Unbreaking on a hoe?
You can, but hoes barely take damage in normal play. Bone meal is more common than hoe-tilled crops at this point, so the enchantment is wasted unless you’re running large-scale farms.
Does Unbreaking stack with itself?
No. You can’t have Unbreaking III and another Unbreaking III on the same item. Combining the two books just gives you Unbreaking III on the result.
What’s the difference between Unbreaking and Mending?
Unbreaking reduces the chance that each use damages the item. Mending repairs the item with experience orbs you pick up. They’re separate effects and both apply on the same item.
Does Unbreaking affect block-breaking speed?
No. That’s Efficiency. Unbreaking only affects durability, never mining speed or damage output.
Bottom line
Unbreaking is one of the few enchantments worth putting on essentially everything you plan to keep. It isn’t flashy, but the math compounds. A pickaxe that lasts four times longer means four times fewer trips to the crafting table, fewer diamonds spent, and more time mining. Pair it with Mending on the items that matter most and your gear stops being consumable.
