Hey, I’m Yuzukaki.
You finally crafted your favorite gear and tools… and they break way too fast.
Yeah, that hurts. Been there.
👆 There’s an enchantment that pretty much solves this problem.

If you use Mending well, your gear and tools basically stop breaking, so you can keep your favorites for a long, long time.
The catch: Mending doesn’t show up on a regular enchantment table, and it’s a treasure enchantment—so you need a reliable way to get it.
In this article, I’ll go from a simple overview of Mending all the way to one efficient way to actually obtain it, based on real in-game testing.
If you read through to the end, you should have a solid plan for getting Mending in survival.
- This article is for beginners who want “almost unbreakable” gear and tools.
- All testing was done on Minecraft Java Edition 1.21.x (the 1.21 series).
- This article was published as an English translation of a Japanese blog post.

1. What Is Mending? Effects and Main Ways to Get It
1-1. What the Mending Enchantment Does
Mending is an enchantment you put on gear or tools that uses experience orbs to restore that item’s durability.


Example: a simple way to use Mending 1. Hold the damaged tool in your main hand (or wear the damaged armor). 2. Gain experience orbs (XP orbs) from an XP farm or any XP source. 3. Let the orbs repair the item with Mending.
One small tip: if you have multiple Mending items equipped, the game can spread repairs around.
So when you really want to repair one specific tool fast, hold it and take off other Mending gear temporarily.
If you play like this, you can keep using your favorite tools and armor for a very long time without “real repairs.”
1-2. How You Can Get Mending
Let’s talk about how to actually obtain Mending.
Short version: if you want it on your favorite gear, you’ll usually want it as an enchanted book.
Main ways to get a Mending book:
- Trade with a Librarian villager (often called the “Librarian gacha”)
- Fishing as a treasure item
- Looting chests in certain structures (for example: Jungle Temples, Strongholds, and Ancient Cities)
So realistically, your options are:
- Villager trading, or
- Lots of fishing, or
- Exploring and clearing dangerous structures
For beginners:
- Structures: hard to find, and clearing them can be rough early on.
- Fishing: you need the right setup and patience to chase treasure loot.
👉 So if you’re just starting out and want something reliable, the best path is Librarian gacha.
“Librarian gacha” means:
You make a villager take the Librarian job, check their trades, and if they don’t sell the book you want, you reset them and try again. You repeat this until you get the exact book (Mending) that you’re looking for.

From the next chapter on, I’ll walk through real measured data from 477 Librarian rolls in survival, and explain the appearance rate and the average price for getting Mending.
※ Quick note: there’s an experimental “Villager Trade Rebalance” setting that changes Librarian book availability.
If you’re playing normal survival settings (no experiments enabled), the classic reroll method in this article works as written.
2. 【Measured】Mending Librarian Gacha: Appearance Rate and Average Price
In this chapter, I’ll share my real test results:
how often Mending showed up, and what the average price was, based on 477 Librarian rolls.
2-1. Mending: What My Data Looked Like (and What Prices Can Be)
Quick takeaway (rule of thumb)
From 477 rolls:
- Mending appearance rate (measured): 2.31%
→ Roughly 1 Mending every 43 rolls - Average price (measured): 25.8 emeralds
Also, as a baseline reference: in vanilla (before discounts), Mending book trades typically fall within a fixed price range—so your rolls won’t be truly “anything goes.”
So if you’re a beginner doing Librarian gacha for the first time:
If you see Mending for around 24–26 emeralds, it’s absolutely worth locking in.
Now, here’s the measured table these numbers come from:
Prices are written as “number of emeralds”.
| Enchantment | Measured Appearance Rate % | Measured Average Price |
|---|---|---|
| Mending | 2.31 | 25.8 |



👆 All of these screenshots are actual Mending trades that appeared during those 477 rolls.
With a few hundred attempts, you’ll usually see a nice spread—from painful prices to “oh wow, I’m taking this” deals.
Once you get used to the method in Chapter 3, one roll takes less than a minute.
So if you have the patience, getting Mending within about an hour is very realistic.
Side topic: other “must-take” books from the 477-roll data
At the end of this section, here are other books that, based on the 477 rolls, I strongly recommend locking in when you see them.
All of these are:
- Extremely useful in survival, and
Showed up with relatively low probability in my data.
1st: Protection IV (0.21%)
- 2nd: Unbreaking III (0.21%)
- 3rd: Efficiency V (0.42%)
- 4th: Fortune III (0.42%)
- 5th: Silk Touch (0.63%)
※ For reference, here’s the full measured table from the 477 rolls:
| Enchantment | Measured Appearance Rate % | Measured Average Price |
|---|---|---|
| Efficiency V | 0.42 | 52 |
| Looting III | 0.63 | 23 |
| Piercing IV | 0.42 | 30.5 |
| Infinity | 1.47 | 13.7 |
| Sweeping Edge III | 1.47 | 32.1 |
| Respiration III | 1.26 | 26.7 |
| Channeling | 1.47 | 11.9 |
| Mending | 2.31 | 25.8 |

| Riptide III | 0.42 | 25 |
| Thorns III | 0.63 | 15.7 |
| Density V | 0.42 | 43 |
| Quick Charge III | 0.21 | 13 |
| Blast Protection IV | 0.21 | 29 |
| Feather Falling IV | 0.21 | 29 |
| Luck of the Sea III | 0.21 | 28 |
| Projectile Protection IV | 0.21 | 50 |
| Protection IV | 0.21 | 27 |
Again, sample size is only 477, so don’t treat the tiny differences too seriously.
But it gives you a nice feel for which books are rare + strong enough to grab on sight.
3. How to Roll Librarians Efficiently for Mending
Next, let’s go over a simple, efficient way to do Librarian gacha with screenshots.
We’re focusing on beginners here, so I’ll keep the steps clean and repeatable.
- Place a Lectern to make a villager take the Librarian job.
- Open the trades and check what book they sell.
- If they don’t have the book you want:
→ Break the Lectern to make them unemployed again, then go back to step 1.- If they do have the book you want (like Mending):
→ Trade with them once to lock in their trades (this step is absolutely crucial).
If you repeat this flow, once you get used to it, one roll takes less than a minute.
[Step-by-step with screenshots]


👉 Pattern ①: When it’s not the book you want


👉 Pattern ②: When it is the book you want

That’s the whole loop.
It’s honestly a bit of a grind, and there will be times when you start wondering if Mending is even real because it just won’t show up.
But statistically, as long as you keep rolling, you’ll almost certainly get the book you’re after.
When you actually do your own Librarian gacha, feel free to refer back to the appearance-rate and average-price table in Chapter 2 as a mental guide.
4. Summary
Thanks for reading all the way to the end.
Let’s quickly recap the key points:
- With Mending, you can keep your tools and armor working for a very long time by repairing them with experience orbs.
- The most reliable way for beginners to get Mending is rolling Librarian villagers (Librarian gacha).
- In my 477-roll test, Mending showed up 2.31% of the time, with an average price of 25.8 emeralds.
In other words, with this one enchantment, you can keep using your favorite gear for basically your whole survival playthrough, so it’s a must-have.
I hope this helps you get Mending efficiently and make your Minecraft life a lot more comfortable.
That’s it for this time.
Thanks again for stopping by!
