Unbreaking — complete enchantment guide in Minecraft

Unbreaking — complete enchantment guide in Minecraft

Unbreaking is one of the basic enchantments in Minecraft that extends the lifespan of gear by reducing durability loss during use. This enchantment can be applied to almost any item with durability: tools, weapons, armor, fishing rods, shields, and elytra. The main thing to grasp immediately is that Unbreaking does not repair an item, but only gives a chance that its next use won't consume a durability point. Below is a detailed breakdown of how this chance works, why the effect differs drastically between tools and armor, how to obtain all three levels, and where this enchantment saves the most resources.

How the durability preservation chance works

Every time an item would normally lose a durability point, the game rolls a hidden "dice". With a certain probability, the durability consumption is canceled – and the counter remains unchanged. The higher the enchantment level, the more often the consumption is skipped. The maximum level is III.

There is one key limitation: no level makes an item infinite. There is always a chance to lose durability, so sooner or later the item will break. The only difference is how many uses it will withstand on average.

Effect on tools and weapons

For tools and weapons, the probability that a use will consume durability is 100 ÷ (level + 1) percent. Therefore, the chance to preserve durability per use is:

• Unbreaking I – 50%

• Unbreaking II – about 66.7%

• Unbreaking III – 75%

On average, the item lasts (level + 1) times longer – twice, three times, and four times respectively. On a pickaxe, axe, shovel, hoe, sword, bow, crossbow, or mace, this directly translates into the number of blocks mined or hits until it breaks.

Effective durability by materials (without enchantments → I → II → III):

These numbers are averages, not guarantees: a specific item may last slightly less or more due to the randomness of the rolls. But over a distance of hundreds of blocks, the deviation is minor, and a netherite pickaxe with Unbreaking III realistically mines around eight thousand blocks.

Why armor benefits much less

For armor, a different, harsher formula applies: the probability of consuming durability equals (60 + 40 ÷ (level + 1)) percent. Because of this, each hit to armor has only a ~20% / 26.7% / 30% chance to pass without durability consumption. On average, armor lasts longer by only +25% / +36.4% / +42.9%.

The difference is clearly visible when directly comparing the chance to preserve durability:

Special items: elytra, fishing rod, shield, trident

A few items are calculated using the tools formula, so they benefit maximally from the enchantment.

Elytra receive the most noticeable benefit. They lose one durability point per second of flight, so the basic 432 durability is 7 minutes and 12 seconds in the air. Unbreaking multiplies this time the same way as tool durability:

Since elytra breaking in mid-air is dangerous, this enchantment is almost always applied to them.

A fishing rod loses several durability points at once when it hooks a mob instead of a fish. In such cases, the preservation chance is rolled separately for each consumed point – part of the loss can be mitigated, part cannot. The same step-by-step rolling principle also applies when armor takes multi-point damage, for example from a TNT explosion.

The shield (336 base durability) and trident receive the standard ×2 / ×3 / ×4, so Unbreaking significantly extends their lifespan as well.

How to get Unbreaking

This is a common enchantment with a weight of 5 – one of the most frequent in the game, so it's not hard to obtain. There are several main ways.

Enchanting table

On the enchanting table, Unbreaking is available for primary items: pickaxe, shovel, axe, hoe, fishing rod, sword, bow, crossbow, trident, mace, helmet, chestplate, leggings, boots, and turtle shell. Place the item in the slot, spend lapis lazuli and experience levels, and choose the option with the desired enchantments.

The more bookshelves there are around the table (up to 15, with one block of air in between), the higher the available levels and the greater the chance of getting strong enchantments. A single enchantment can yield a whole set – for example, "Efficiency IV" and "Unbreaking III" on a pickaxe.

Anvil and enchanted book

Secondary items cannot be enchanted from the table this way – only via an enchanted book on an anvil. These include shears, flint and steel, shields, carrot on a stick, warped fungus on a stick, elytra, and brush. The scheme is simple: item in the first anvil slot, "Unbreaking" book – in the second.

Through the anvil, you can also combine duplicates: two "Unbreaking II" books yield one "Unbreaking III". However, two III books in survival will not raise the level any higher – III remains the cap.

Trading, fishing, and structure loot

An enchanted book with this enchantment can be traded from a librarian villager for emeralds, pulled during fishing, found in dungeon chests, and in non-village structure loot. Equipment with already applied Unbreaking is sometimes worn by enemies that spawned with enchanted gear.

How much the enchantment costs

The experience level required at the table affects which enchantments and of what level can drop. The internal thresholds for Unbreaking are as follows:

In practice, III starts appearing around levels 20–22, especially on books. A higher price (up to 30 levels with 15 bookshelves) does not change the III ceiling but increases the chance to get a strong set in one try. At the anvil, the base cost of applying an "Unbreaking III" book is small, but each subsequent combination increases the prior work penalty, and eventually the anvil may say "Too Expensive!".

Unbreaking through commands

In creative mode or with cheats enabled, enchantments are applied using commands.

The /enchant command works according to the regular enchanting rules and applies to the item in the main hand:

/enchant @p minecraft:unbreaking 3

It won't let you exceed III and won't apply the enchantment to an incompatible item. To bypass the III limit, use /give with the enchantments component. In versions 1.20.5–1.21.4, the format is:

/give @p minecraft:diamond_pickaxe[minecraft:enchantments={levels:{"minecraft:unbreaking":10}}] 1

In newer versions, the component was simplified, and the same item is given shorter:

/give @p diamond_pickaxe[enchantments={"minecraft:unbreaking":10}]

The maximum level via commands in Java Edition is 255. The behavior beyond the limit is linear: each subsequent level continues to reduce the chance of consuming durability by the same formula.

Common mistakes and how to avoid them

Thinking the item is indestructible. Even at III, there remains a 25% chance to consume durability per use, and on armor – a full 70%. Expect a longer lifespan, not immortality for your gear.

Enchanting armor expecting the same effect as on a pickaxe. Armor benefits far less due to the 60% threshold. If resources are limited, enchant tools and elytra first.

Confusing it with Mending. Unbreaking slows down wear, Mending restores durability using experience. These are different enchantments; on durable gear, they are usually kept together.

Trying to apply III from the table to elytra, shears, or a shield. These items are secondary – the enchantment only transfers to them from an enchanted book via an anvil.

Combining two III books for IV. In survival, the ceiling is III. Levels above that are only achievable via commands.

Forgetting about elytra. Without this enchantment, elytra wear out in a few minutes of active flying; Unbreaking III quadruples the air time and removes the risk of breaking at altitude.

Conclusion

Unbreaking stretches the lifespan of gear by reducing the frequency of durability consumption. On tools, weapons, and elytra, the effect is direct and strong: the service life increases two, three, or four times. This makes it one of the first enchantments that make sense to apply to a pickaxe, axe, or netherite set in Minecraft.

Unbreaking shines fully when paired with Mending: the first slows down wear, the second refills durability for experience, and together they keep your favorite gear practically free of manual repairs. For survival, resource gathering, and elytra flying, this is a baseline choice; on pure armor, it is rather placed last, once more critical protection enchantments are already applied.
