Alloygery

Alloygery adds new ores, metals and alloys, and a new way to make them. The changes reach tools and armor, so the progression follows the metals a player has, while the vanilla feel is kept. Tools are assembled from parts such as a pickaxe head and a binding handle at a Smithing Anvil. Each part contributes to the tool's overall stats, so players can mix materials to look for stronger results. A finished tool can then take upgrades at a Smithing Table, and upgrades can be removed again with a smithing hammer.

Armor is built in a similar way. A piece starts from one of three base layers, wool, leather or chain, and is upgraded with plating made at a Smithing Anvil and applied at a Smithing Table. Two plating types are added, Plate and Heavy Plate, along with steel plate and steel heavy plate variants. Plating is removed at a Crafting Table with a crafting hammer. Base layers of wool and leather can be dyed, which gives many color combinations. Diamond and netherite gear is no longer craftable by default, but players can still find it in loot or trades and salvage it for parts.

Alloygery requires Fabric API and runs on Fabric for 1.18.2 and 1.19.2. Installation covers the server and each player's game. The source code and issue tracker are public, and the code is open source under the MIT License.
