Treasure Enchants

This mod adds unobtainable enchanted books as rare loot all across the world.
It's a great endgame feature for SMPs or Vanilla+ Servers.

The mod functions as a server-side only mod, but also works for singleplayer.

Enchantments

The books and where they can be found are 100% customisable.
Here are some examples from the default config:

The book is added to the original loot, so the original loot is not affected.

Full default list:

Anvils

The anvil mechanics had to be changed to support the treasure enchants. There is also a config option to increase the level cost cap of the anvil.

Note: Players without the mod will see the "Too expensive!" text, but the items can be combined anyway.

Configuration

The config is generated at config/treasure_enchants.json. All values can be updated with /reload.

{
    "anvilCostLimit": 40,
    "enchants": [
        {
            "lootKey": "chests/end_city_treasure",
            "chance": 2.5, "luckFactor": 0.5,
            "enchantments": [ { "enchantKey": "sharpness", "level": 6 } ]
        },
        {
            "lootKey": "chests/woodland_mansion",
            "chance": 2.5, "luckFactor": 0.5,
            "enchantments": [ { "enchantKey": "infinity", "level": 1 }, { "enchantKey": "mending", "level": 1 } ]
        }
    ]
}

lootKey is the resource location of the loot table.
chance is the probability of the book to appear, in percentage, with 1 decimal precision.
luckFactor is multiplied by the player's luck of the sea enchantment (or luck effect) and added to chance.

The minecraft: namespace is optional, but for custom enchants/loottables, you need to add the namespace of the mod/datapack: my-mod:my_cool_enchant

Installation Notes

Requires Fabric API and Fabric Language Kotlin.

Only the server needs the mod. Players can join with a vanilla client. For singleplayer, install it like any other mod.

The mod works in existing worlds. Chest loot is generated the first time a chest is opened.
