🔧 EnchantOnce — Enchanting & Repair Overhaul

A lightweight configurable mod that removes enchanting frustration and overhauls enchanting and anvil mechanics: control XP costs, rework anvil repairs, extract and copy enchantments, and duplicate fully enchanted gear.

Find a rare enchanted book or item once — and never worry about losing it again.

🎯 Who is this mod for?

EnchantOnce is for players who enjoy enchantments but are tired of grinding XP and repeating the same rituals.

If you prefer a smoother, more controlled experience — where your best finds actually matter — this mod is for you.

📌 Features

🛠️ Flat Repair Cost

Repairing a damaged item with its base material always costs 2 experience levels — no matter how many times it's been repaired.
The "Too Expensive" limitation is removed entirely.
Prior anvil work history is preserved during repairs (it is not reset or increased).

🔄 Repair with Materials

Repair tools and gear using base materials, instead of combining duplicate items.

Repair rare items like tridents

Item	Repair Material	Amount Repaired
Shield	Any Planks	½ durability
Shears	Iron Ingot	Full durability
Bow, Crossbow	String	¼ durability
Fishing Rod	String	¼ durability
Carrot on a Stick	String	¼ durability
Warped Fungus on a Stick	String	¼ durability
Flint & Steel	Flint	Full durability
Trident	Prismarine Shard	¼ durability
Brush	Feather	¼ durability
Elytra	Phantom Membrane	Full durability

➡ Only works if the item is damaged. The material is consumed.

📖 Duplicate Enchanted Books

Copy enchanted books using blank books.

Duplicate Enchanted Books

Place one enchanted book in the left slot and up to 4 normal books in the right.
Output: up to 5 copies of the enchanted book (original + up to 4 more).
XP cost depends on the enchantments:
- Calculated from the minimum enchantment cost values.
- Curses are ignored in the cost.
- Total cost = (number of new copies) × (combined cost of enchantments).
- Minimum cost per copy is always 1 level.

This system prevents XP farming via book copying + grindstone trickery. Prior anvil work history is preserved and copied to all resulting books.

📚 Extract Enchantments

Move all enchantments from any enchanted item to a single enchanted book.

Extract Enchantments

Place the item in the left anvil slot, and a book in the right.
The item must be completely intact (no damage).
Output is one enchanted book with all enchantments.
By default, the original item is destroyed in the process.
If enabled in the config, the original item is kept, but all curses remain on it and its prior anvil work history is preserved.
XP cost: 1 level.
This is the only operation that resets the history on the resulting book.

🧬 Clone Enchanted Items

Create a perfect duplicate of any enchanted item.

Clone Enchanted Items

Place the enchanted item in the left slot and an unenchanted item of the same type in the right.
Both items must be completely intact (no damage).
Output: a copy with the same enchantments.
XP cost: 25 levels.
Anvil work history is preserved and copied to the result.

🔻 Downgrade Enchanted Books (Flint)

(Available since 2.0.0 mod version)

Lower enchantment levels on enchanted books using Flint.

Downgrade Enchanted Books

Place an enchanted book in the left anvil slot and Flint in the right.
All non-curse enchantments have their level decreased by 1.
Enchantments that reach their minimum level are removed.
Curse enchantments are never modified.
If no enchantment can be downgraded, the operation is cancelled.

Cost:

XP: 1 level
Material: 1 Flint

This provides a controlled way to adjust enchantment strength without relying on random rerolling or grindstone abuse.

⚖️ Vanilla Enchantment Combination Change

(Available since 2.0.0 mod version)

The vanilla enchantment level increase mechanic has been intentionally disabled.

In vanilla Minecraft, combining two enchanted books or items with the same enchantment level increases the resulting enchantment level. This behavior makes sense in vanilla, because enchanted books and items are effectively single-use and cannot be duplicated.

EnchantOnce introduces the ability to duplicate enchanted books and clone enchanted items. Without adjusting vanilla behavior, this would allow players to reach maximum enchantment levels simply by repeatedly cloning and combining items.

To preserve balance and prevent enchantment scaling:

Combining two books or items with the same enchantment level no longer increases the resulting enchantment level.
The highest existing level is preserved instead.

This change is intentional and required for compatibility with the mod’s duplication mechanics.

🌪️ Wind Burst — Controlled Vanilla Scaling

(Available since 2.2.0 mod version)

In vanilla Minecraft, Wind Burst is a special-case enchantment:

It only generates at level I in Trial Chambers.
Its intended progression relies on combining multiple level I books to increase its level.
Without vanilla scaling, Wind Burst would become permanently locked at level I.

Since EnchantOnce disables vanilla enchantment level scaling by default, Wind Burst requires a carefully controlled exception to preserve its intended gameplay — without opening duplication exploits.

🔒 Wind Burst Lock Mechanic

EnchantOnce introduces an internal, book-only marker enchantment:
Wind Burst 🔒

Wind Burst Lock

This marker is not obtainable by players and exists solely to control Wind Burst scaling behavior.

⚖️ Scaling Rules

Wind Burst enchantment level scaling follows a single consistent rule:

Allowed:

Wind Burst can increase in level if the item in the right slot is an Enchanted Book without the 🔒 lock

Blocked:

In all other cases, Wind Burst will not scale, including:
- The right slot item is not a book
- The right slot book has the 🔒 lock
When scaling is blocked, the highest existing level is preserved

📚 Lock Propagation

The 🔒 lock is automatically applied in the following cases:

Enchanted Book Duplication
- When duplicating a vanilla Wind Burst book:
- The original and all copies receive the 🔒 lock
- Resulting books can no longer be used for scaling
Book Combination
- When combining two Enchanted Books containing Wind Burst:
- If either book has the 🔒 lock, the resulting book also receives it
- This applies even if the enchantment level increases
Enchantment Extraction
- If Wind Burst is extracted from an item onto a book:
- The resulting book receives the 🔒 lock
- Prevents item → book → combine scaling loops
Downgrading with Flint
- The 🔒 lock behaves like a Curse:
- It is preserved while Wind Burst remains on the book
- It is removed automatically if Wind Burst is completely removed

🛠️ Item Behavior

When applying Wind Burst to an item (e.g. Mace):
- The 🔒 lock is not transferred
- The lock exists only on enchanted books

Items can still be duplicated, repaired, and extracted normally without enabling unintended scaling paths.

✅ Result

Vanilla Wind Burst progression is preserved
Duplication and cloning remain fully supported
Infinite enchantment scaling is prevented
Wind Burst is the only enchantment allowed to scale, under strict conditions

⚙️ Configuration
