SmitherZ is a minecraft mod which adds the ability to upgrade armor, tools and weapons with gems.

SmitherZ is a mod built for the Fabric Loader. It requires Fabric API and Cloth Config API to be installed separately; all other dependencies are installed with the mod.

SmitherZ is licensed under MIT.

Gems can be created, gem drops can be set (mainly for RpgDifficulty compat) and item socket count can be set (mainly for TieredZ compat).
If you don't know how to create a datapack check out Data Pack Wiki website and try to create your first one for the vanilla game.
If you know how to create one, the folder path has to be data\modid\FOLDER\YOURFILE.json.
The FOLDER is gems for new gems, gem_drops for adding gem drops and gem_upgrades for item socket count.
For creating new gems you have to put the datapack under .minecraft\global_packs\required_datapacks\YOURDATAPACK.
If you created new gems via the global datapack, you will want to texture and translate them by creating a resource pack. To load resource packs globally, it will require a global datapack loader.

Example for a new gem json:

{
    "new_gem_name": {
        "link_chance": 0.1, // chance to link gem to item
        "break_chance": 0.1, // chance to break whole item on link fail
        "unlink_chance": 0.1, // chance to unlink gem
        "attributes": [
            {
                "type": "generic.max_health",
                "modifier": {
                    "operation": "ADD_VALUE",
                    "amount": 2
                }
            }
        ],
        "tag": "minecraft:swords"
    }
}

Example for a gem drop json:

{
    "rarity_0": {
        "items": [
            "smitherz:strength_1_gem",
            "smitherz:strength_2_gem"
        ],
        "drop_chance": 0.01, // chance for droping a random item of the item list
        "mob_types": [
            "minecraft:spider" // only mobentity types
        ],
        "rarity_group": 0, // for general rarity
        "difficulty_multiplier": 1.1 // rpg difficulty compat
    }
}

Example for a socket count json:

{
    "2": [ // socket count
        "tiered:common_armor_1", // nbt string of an item
        "tiered:common_armor_2",
    ]
}
