Unbreaking is one of the most universally useful enchantments in Minecraft, and it shows up on nearly every piece of gear worth keeping. In short: Unbreaking gives each use of an item a chance to not consume durability, effectively extending how long that tool, weapon, or armor piece lasts before it breaks. This guide covers the exact mechanics, the real save-chance values, which items qualify, and how to apply it.
How Unbreaking Works
Unbreaking does not increase an item’s maximum durability number. Instead, every time an item would normally lose a durability point, the game rolls a chance to skip that loss. Over hundreds of uses, that skipped wear adds up to a dramatically longer lifespan.
The important detail is that Unbreaking behaves differently on tools and weapons than it does on armor.
Tools, weapons, and other non-armor items: the chance a use consumes durability is 1 / (level + 1), so the chance to save a durability point is level / (level + 1). That works out to:
- Unbreaking I: 50% chance to save each point (roughly 2x average lifespan)
- Unbreaking II: 66.67% chance to save (roughly 3x average lifespan)
- Unbreaking III: 75% chance to save (roughly 4x average lifespan)
Armor: the math is deliberately weaker. The chance a use reduces durability is 60% + 40% / (level + 1), so the chance to save is only 40% − 40% / (level + 1):
| Level | Tools / Weapons (save chance) | Armor (save chance) |
|---|---|---|
| I | 50% (~2x life) | 20% (~1.25x life) |
| II | 66.67% (~3x life) | 26.67% (~1.364x life) |
| III | 75% (~4x life) | 30% (~1.429x life) |
Why the difference? Armor only loses durability when it actually absorbs damage, and each armor durability point already protects against more incoming damage. The reduced Unbreaking benefit on armor is a deliberate balance, not a bug. Want to see how these odds stack up against your specific gear? Try our tool below.
What Items Can Get Unbreaking
Unbreaking splits into two groups depending on whether you can pull it straight from an enchanting table.
Primary items (available directly from the enchanting table): pickaxe, shovel, axe, hoe, fishing rod, sword, bow, trident, crossbow, mace, helmet, chestplate, leggings, boots, turtle shell (helmet), and newer items such as the spear.
Secondary items (only via anvil or enchanted book): shears, flint and steel, shield, carrot on a stick, warped fungus on a stick, elytra, and brush.
Because it works on essentially everything with a durability bar, Unbreaking is a core pick across the board. For gear-specific loadouts, see our best pickaxe enchantments, best sword enchantments, best armor enchantments, and best elytra enchantments guides, or browse the full All Minecraft Enchantments pillar.
Max Level and How to Get It
Unbreaking maxes out at level III (3). You can obtain it from:
- An enchanting table (higher levels need bookshelves and cost XP plus lapis lazuli)
- Trading with librarian villagers
- Fishing
- Monster-room (dungeon) chests and other structure/loot chests
- Enchanted books applied via an anvil
- Raid drops (Bedrock Edition only)
On an anvil you can also combine levels: two Unbreaking I items make II, and two Unbreaking II items make III. Note that combining two level-III items does not exceed III, and each anvil use adds a prior-work penalty that increases the XP cost.
Is Unbreaking Worth It?
For tools and weapons, absolutely. Unbreaking III roughly quadruples average lifespan, which means fewer trips back to the crafting table and far less diamond or netherite spent on replacements. On armor the benefit is smaller (about 1.25x to 1.43x), but it is still free longevity on gear you rarely want to re-enchant.
Crucially, Unbreaking has no conflicting enchantments. It is fully compatible with every other enchantment, including Mending. The classic combo is Unbreaking plus Mending: Unbreaking slows durability loss, while Mending refills durability using experience orbs (2 durability restored per XP point). Together they create gear that is effectively self-repairing, so long as you keep gaining XP.
How to Apply It
Enchanting table: place an eligible tool, weapon, or armor piece in the table with lapis lazuli. Unbreaking is a primary (table-obtainable) enchantment for eligible items; surrounding the table with bookshelves unlocks higher levels.
Anvil: combine your item with an Unbreaking enchanted book, or combine two items that each have Unbreaking to raise the level (I+I to II, II+II to III). This costs XP levels plus the prior-work penalty.
Command: use /enchant (or the short form /enchant ) with a level from 1 to 3. If you run a survival realm for friends, applying enchantments and testing loadouts is easiest on your own world, take a look at our Minecraft server hosting.
Frequently Asked Questions
Does Unbreaking make my item last forever? No. It only reduces how often durability is spent; the item can still break. Pair it with Mending for near-permanent gear.
Why does Unbreaking feel weaker on armor? Armor uses a different formula (60% + 40% / (level + 1) chance to lose durability), so it only saves 20% to 30% of the time. Armor already spreads incoming damage across its durability, so this is intentional balance.
Can Unbreaking and Mending go on the same item? Yes. They have no conflict and are the go-to durability combo.
Does Unbreaking raise my item’s maximum durability? No. The max durability number stays the same, you just spend it more slowly.
What is the highest Unbreaking level? Unbreaking III. Combining two level-III items on an anvil will not push it beyond III.
