Anvils, Mending and Repairing Gear Without Losing It

Losing a fully enchanted pickaxe to durability is one of the most avoidable disappointments in Minecraft. Understanding anvils and Mending means your best gear never wears out — but the anvil has rules that punish careless use, and they are not explained anywhere in-game.

What an anvil does

An anvil has three functions:

• Repair with material. Combine a damaged tool with its base material — iron ingots for iron, diamonds for diamond — to restore durability while keeping enchantments.
• Combine two items. Merge two of the same item. Durability adds together with a bonus, and enchantments merge. Matching enchantments at the same level go up one level.
• Rename. Costs one level and, usefully, counts as an anvil operation for the penalty described below.

Anvils are not indestructible. Each use has a chance to chip and eventually break, so keep a few iron blocks spare.

The Prior Work Penalty — the rule that ruins gear

This is the mechanic behind "Too Expensive!" and almost nobody learns it until a favourite tool becomes unusable.

Every item silently tracks how many times it has been through an anvil. Each use doubles the penalty added to future costs. So the first combine is cheap, the fourth is expensive, and around the sixth or seventh the total cost exceeds 40 levels — at which point survival mode simply refuses the operation. Permanently. There is no way to reset it.

Combining in the right order

Because the penalty compounds per item, the trick is to do as much work as possible on the books rather than on the tool.

Wrong way — five separate operations on the pickaxe, penalty doubling each time:

1. 1.Pickaxe + Efficiency book
2. 2.Pickaxe + Unbreaking book
3. 3.Pickaxe + Fortune book
4. 4.Pickaxe + Mending book

Right way — merge books with books first, so the tool only takes one or two hits:

1. 1.Efficiency book + Unbreaking book = combined book
2. 2.Fortune book + Mending book = combined book
3. 3.Combine those two books together = one book with all four
4. 4.Pickaxe + that single book

Same result, a fraction of the cost, and the pickaxe keeps a low penalty for future repairs. Our max enchantments tool shows every enchantment a given item can hold, which makes planning the full set straightforward before you spend anything.

Mending: the enchantment that changes everything

Mending repairs an item automatically using experience orbs you collect while the item is held or worn. Pick up XP with a Mending pickaxe in hand and the durability goes up instead of your level.

Two things to know:

• Mending cannot be obtained from an enchanting table. It is a treasure enchantment. You get it from fishing, chest loot in structures, or — by far the most reliable route — trading with a Librarian villager. Our villager workstation guide explains how to reroll a Librarian until Mending appears.
• Mending and Infinity cannot coexist on a bow. You must choose. Infinity saves arrows; Mending saves the bow. Most players prefer Mending on a good bow and keep a stack of arrows.

Once a tool has Mending, it never needs the anvil again for durability, which means the Prior Work Penalty stops mattering. That is the real goal: get Mending on early, and the item is effectively permanent.

The grindstone: your undo button

A grindstone strips all enchantments from an item and refunds some experience. Two good uses:

• Clearing a bad enchant so you can start fresh, and importantly, the grindstone also resets the item's repair cost, though it removes every enchantment doing so.
• Salvaging villager gear. Weaponsmith and Armorer villagers sell enchanted diamond items cheaply. Grinding off the unwanted enchantments leaves you a clean diamond item for the cost of a few emeralds.

Note that a grindstone will not remove curses — Curse of Binding and Curse of Vanishing stay.

Practical routine for a main tool

1. 1.Get the tool. Diamond or netherite.
2. 2.Buy or find Mending first, before anything else.
3. 3.Plan the full enchantment set using the max enchantments tool.
4. 4.Merge all the books together, book-on-book, until you have one.
5. 5.Apply that single book to the tool.
6. 6.From then on, let Mending handle repairs. Never anvil it again.

If you are enchanting from a table rather than trading, our enchantment table calculator shows the level ranges each slot can offer for a given bookshelf count, so you can tell whether it is worth spending the levels now or waiting.

Netherite and repair

Upgrading a diamond item to netherite with a smithing template keeps all enchantments and the durability state, and it does not add a Prior Work Penalty. So enchanting a diamond tool fully and then upgrading it is a perfectly efficient path — you do not need to wait for netherite before investing books.
