Minecraft 1.21.1, NeoForge

Akashic Record

A mod for Minecraft 1.21.1 on NeoForge (Java 21). It offers a simplified alternative to the EMC and "transmutation" system from ProjectE: focus on learning items and obtaining them using "Knowledge" points.

How it works

Craft the Akashic Record book (or obtain it from the "Tools" tab in the Creative Inventory) and right-click to open it.

The left-hand page displays your Knowledge points and various categories:

• Learn Item: A list of items currently in your inventory appears on the right.
• Storage: A personal storage space for items that cannot be "learned" (e.g., items with no Knowledge value, enchanted items, or items with custom names). The right side features two sections: "From Inventory" (Left-click to add 1 item; Shift+Left-click to add all matching items) and "In Storage" (Left-click to remove 1 item; Shift+Left-click to remove all; Right-click to remove half). Storage capacity is defined by the storageSlots setting in the config (default is 108 slots/stacks). Contents are preserved upon death.
• All Items: A collection of everything you have already learned.
• Potions: Learned potions, including splash and lingering variants (each type and effect is tracked individually).
• Enchanted Books: Learned enchanted books (each enchantment and level is tracked individually).
• Additional categories corresponding to the tabs in the Creative Inventory (Blocks, Nature, Tools, Food, etc.; only categories containing learned items are displayed). The quantity of items is indicated next to each entry.

The right-hand page displays rows of items from the selected category, along with a search bar.

Learning. In the "Learn Item" category, clicking an item learns it: Left-Click consumes 1 unit from your inventory, while Shift+Left-Click consumes all units of that item. The item disappears, its value is added to your Knowledge points, and it becomes available for acquisition. Newly learned items are highlighted in green and appear at the top of the list.

Acquisition. In any other category, clicking an item allows you to obtain it in exchange for Knowledge points: Left-Click for 1 unit, Shift+Left-Click for a full stack, and Right-Click for half a stack. Items for which you lack sufficient points are marked in red.

The mouse wheel scrolls the page over which the cursor is positioned.

Knowledge belongs to the player (not the book) and persists after death. Items containing additional data (such as enchantments, custom names, or durability damage) cannot be learned; the "Akashic Record" book itself cannot be learned either. Furthermore, the book cannot be placed into storage containers.

Recipe for the book (shapeless): Book + Diamond + Ender Pearl + Lapis Lazuli.

Source of Values ​​("Knowledge")

The order of precedence is as follows:

1. ProjectE (if installed and useProjectE = true is set in the config): The value is determined by the item's EMC from ProjectE. Values ​​are retrieved via reflection, so ProjectE is not a hard dependency.
2. Datapacks (data/<namespace>/knowledge_values/*.json): Explicitly defined values ​​(these take precedence over derived values). The mod's own base.json file is skipped when ProjectE is in use.
3. Derivation from recipes (if deriveFromRecipes = true and ProjectE is not in use): for items lacking a defined value, the value is calculated based on the cheapest recipe found in a crafting table, furnace, or stonecutter.

Potions and Enchanted Books

Since these are single items with varying data, they are evaluated separately from standard items, regardless of whether ProjectE is used.

Potions. Values ​​are defined in the data/akashic_records/knowledge_potions/potions.json file:

{
"splash_extra": 64,
"lingering_extra": 64,
"potions": { "minecraft:healing": 619, "minecraft:strong_healing": 747 }
}

This represents the price of a standard potion; splash potions cost an additional splash_extra, while lingering potions cost an additional lingering_extra. A value of 0 disables the potion. Potions not listed in the table (such as a Water Bottle or potions from other mods) cannot be learned, though they can still be placed into storage. Potions with custom effects or names also cannot be learned.

Enchanted Books. The price is calculated using the following formula:

Knowledge = ((base * 10) / enchantment_weight) * 2^(level - 1)

The weight is derived from the enchantment's registration within the game, while the base value is determined by the enchantedBookBase parameter in the configuration (defaulting to 8192). Only books containing a single enchantment—with a level ranging from 1 to the maximum—can be learned. Books with multiple enchantments or higher enchantment levels can be placed into storage.

File format for standard item values:

{
"minecraft:diamond": 8192,
"#minecraft:logs": 32,
"minecraft:bedrock": 0
}

A key starting with # defines an item tag. A value of 0 (or less) bans the item: it cannot be learned, and it is excluded from recipes.

Commands (Permission Level 2)

• /akashic recalc recalculates item values ​​(useful after /reload or if ProjectE loaded later) and syncs them to players.
• /akashic add <amount> adds Knowledge points to the user (for testing purposes).

Config

akashic_records-common.toml: useProjectE, deriveFromRecipes, storageSlots, enchantedBookBase.

A Word from the Author

"I've never been a fan of heavy tech mods, yet ProjectE has always been my one exception. I fell in love with its transmutation system, though all the extra blocks, stations, trinkets, and gadgets were never really my style.

That's how Akashic Record was born. It strips everything down to the single core mechanic I truly wanted—pure, portable transmutation."
