What a table can really give you, with the odds. Not a list of what exists, but what your item at your bookshelf count actually rolls.
Out of 10,000 tries on the bottom offer. An offer gives 1.97 enchantments on average.

Higher is better, and it does not follow the material. Gold is 22 to 25 and diamond is 10, so a golden sword takes better enchantments than a diamond one at the same cost. It just breaks sooner.
You need all 15 bookshelves. Each one sits two blocks from the table with the gap between them clear, level with the table or one block higher. Anything in that gap stops the shelf counting, so keep torches and slabs out of the ring.
Mending, Frost Walker, Soul Speed, Swift Sneak, Wind Burst and both curses. Those come from fishing, trading, loot chests and villagers only, however many bookshelves you have.
How it works
- Pick the item and how many bookshelves you have around the table.
- Choose one of the three offers. The levels under each one are exactly what that slot can show you.
- Read the odds. The chance is how often that enchantment turns up on that offer, and the levels beside it show which strength you are likely to get.
- Enchanting a book and moving it across with an anvil is often cheaper. The other tools cover the rest of the command side.
Java Edition. The odds come from running the game's own selection procedure ten thousand times, not from a fixed table, because the game has no fixed table to copy.
Questions
- Can I get Mending from an enchanting table?
- No, and no number of bookshelves changes that. Mending is a treasure enchantment, and a table only draws from its own list, which leaves those out. Mending comes from fishing, from raid drops, from loot chests and from librarian villagers. Frost Walker, Soul Speed, Swift Sneak, Wind Burst and both curses are in the same position.
- How many bookshelves do I need for level 30?
- Fifteen, and no more: the game ignores any beyond that. They go two blocks out from the table with the gap between clear, level with the table or one block up. Anything sitting in that gap stops that shelf counting, which is why a torch on the wrong wall costs you levels.
- Why does gold get better enchantments than diamond?
- Because enchantability is its own number and it does not follow the material. Golden armor is 25 and golden tools are 22, against 10 for anything diamond. That number feeds straight into the hidden roll, so gold gets more and better enchantments for the same experience cost. It just wears out much faster, which is why people enchant gold and then move the result onto something durable with an anvil.
- Are these percentages exact?
- They are the game's own procedure run ten thousand times, so they are accurate to about a tenth of a point. There is no exact table to give you: the game rolls a hidden cost from your experience cost and the item's enchantability, and only then decides what is on offer. That is why two players with identical setups see different offers.
- Why does a book usually come out with only one enchantment?
- Because the game takes one away. A book that rolls several enchantments has one removed at random before you see it. Everything else keeps all of them, which is why an enchanted book is so often a single line while a sword from the same table has three.
- What does the top slot actually cost me?
- Less than it looks. The big number is how many levels you must have, not what you pay. What you pay matches the lapis: one of each for the top slot, two for the middle, three for the bottom. So the top offer costs you a single level even when it says nine, and you still need nine levels to press it.
- Should I always take the bottom offer?
- Usually yes for gear, because a higher cost means more and better enchantments. The exception is when you want one specific thing: a cheap offer draws from a smaller list, so it can be an easier way to land the one enchantment you are after. The table here shows both, so compare the slots before you spend.
- Does the item I put in change what I am offered?
- Yes, twice over. Only enchantments that belong on that kind of item are considered at all, and the item's enchantability shifts the hidden roll. A book is the exception: every enchantment the table knows can land on one.
