Step one: build a full strength table
An enchanting table costs one book, two diamonds and four obsidian. Placed on its own it offers weak options, roughly level 8 at best. To unlock level 30 enchantments you need 15 bookshelves around it, and no more than 15 will ever count.
- Shelves must sit on the same level as the table or one block above it, exactly two blocks away along one axis and at most two along the other, with one block of air between shelf and table.
- Nothing can block the gap in a way the game counts as blocking. Torches, carpets and snow layers are the usual culprits. The safe approach is to leave the ring completely empty.
- The standard build is a five by five footprint: a ring of two block high shelves around the table, with a gap for the entrance. That gives you the 15 you need with room to spare, and spare shelves do no harm.
Build the shelf ring after you have the table, not before. It is easy to place a table in the middle of a finished room and discover that a shelf is one block too close, and moving 15 shelves is more annoying than building them once in the right place.
Step two: why level 30 is the sweet spot
The table shows three options whose level requirements can read as high as 30, but choosing one only deducts 1, 2 or 3 levels. Standing at level 30 and taking the third option costs you three levels and gives you the best roll available. That single fact is why level 30 enchanting is the standard, and why no one enchants at level 40.
The cost of levelling rises with every level. Going from 0 to 30 takes 1395 experience points, while going from 30 to 33 costs over 300 more on its own. That is why hoarding levels is wasteful. Enchant at 30, then go earn more.
Each enchantment also consumes one to three lapis lazuli, matched to the option. The offers do not change until you actually enchant something, so if you dislike all three, enchant a cheap item or a book to reroll the list. Enchanting a book is often the better reroll because a bad book is still worth combining later.
One warning about expectations: even a level 30 roll is random. It guarantees a good chance at multiple enchantments, not a guarantee of the exact ones you wanted. A level 30 pickaxe can still come back with Efficiency III and nothing else, which is why most serious players enchant a stack of books and combine them rather than rerolling gear over and over.
Step three: the anvil and its ceiling
An anvil combines two items of the same type, or an item and an enchanted book, and can rename things. The catch is that every anvil use adds a work penalty to the item, and the next operation roughly doubles the cost. In Java survival, any single operation that would cost 40 levels or more shows Too Expensive! and cannot be performed.
The practical consequence is that order matters more than total enchantment value. Two items with the same enchantments can cost wildly different amounts depending on how you combined them.
- Merge books before touching gear. Combine enchanted books in pairs first, then apply one finished book to the item. It costs far less than adding books one at a time.
- Put the expensive enchantment on last. The penalty grows with each operation, so the cheapest order is cheapest operation first, most expensive last.
- Renaming counts as an operation. If you want a custom name, do it during the final merge rather than as an extra step afterwards.
If an item is already too expensive to improve, the grindstone is the exit. Stripping it and starting again usually costs less than fighting the penalty.
The grindstone removes enchantments
A grindstone strips every non curse enchantment from an item and returns some experience. Two uses: clearing a bad roll so you can re-enchant, and recycling enchanted gear you picked up from mobs into a little experience.
It also removes the work penalty history along with the enchantments, which is the part people forget. A sword that is too expensive to combine becomes a plain sword that can be enchanted from scratch.
Enchantments the table cannot give you
| Enchantment | Main source | What it does |
|---|---|---|
| Mending | Librarian trades, fishing, loot chests | Repairs gear with collected experience. Effectively mandatory late game. |
| Soul Speed | Bartering with piglins, bastion chests | Faster movement on soul sand and soul soil. |
| Swift Sneak | Ancient city chests | Faster movement while crouching. |
| Frost Walker | Trades, chests, fishing | Turns water to ice as you walk on it. |
| Wind Burst | Ominous vaults in trial chambers | Mace only. Launches you upward after a hit. |
The reliable route to Mending is a librarian who sells it. Rerolling a lectern until the first trade is Mending is a well known and entirely legitimate technique, and it is worth an hour of your time once. After that you never think about repairing gear again.
A practical priority list
- Pickaxe: Efficiency V, Unbreaking III, Mending. Keep a second pickaxe with Fortune III for ores and a third with Silk Touch for glass and amethyst.
- Sword: Sharpness V, Looting III, Sweeping Edge III on Java, Unbreaking III, Mending.
- Armour: Protection IV across the set, Feather Falling IV and Depth Strider III on boots, Respiration and Aqua Affinity on the helmet.
- Bow: Power V plus either Infinity or Mending. They are mutually exclusive, so decide whether you want free arrows or a self repairing bow.
Enchant in this order and you will have a working set long before you have a perfect one. A full set of Protection IV with Mending is worth more than one perfect sword and no armour.
