EnchantOnce

🔧 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).

🚫 Remove "Too Expensive"

(Available since 2.6.0 mod version)

Remove the vanilla anvil restriction that blocks operations costing 40 levels or more.

• Allows all valid anvil operations regardless of XP cost.
• The displayed XP cost is preserved and must still be paid.
• Does not reduce XP costs.
• Works independently from other EnchantOnce features.

This option is controlled by:

allowHighAnvilCost = true

🔄 Repair with Materials

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

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

📖 Duplicate Enchanted Books

Copy enchanted books using blank 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.

• 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.

• 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.

• 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.

Vanilla behavior (config option preventIncreaseEnchantmentLevel = false):

Modified behavior, set by default (config option preventIncreaseEnchantmentLevel = true):

🌪️ 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 🔒

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

(Available since 2.4.0 mod version)

EnchantOnce now includes a fully configurable system that allows you to enable, disable, or tweak nearly every feature of the mod.

You can even disable all mechanics and effectively restore full vanilla behavior — making the mod completely non-intrusive if desired.

📁 Config Location

The configuration file is generated automatically after launching the game and can be found in the standard mod config directory.

By default, it is located at: config/enchantonce-common.toml

Since EnchantOnce 2.6.1 for NeoForge, configuration options can also be changed through the in-game config screen.

From the main menu, navigate to Mods → EnchantOnce → Config to access the configuration options.

✅ Mod Compatibility

• Compatible with vanilla items and most modded gear that follows NeoForge standards.
• Fully supports custom items from my The Block of Angel mod.
• No custom blocks, items, or GUIs — purely vanilla mechanics.

💡 Philosophy

You're not meant to re-grind enchantments forever.
You earned them — keep them. This mod respects your time and your progress.
