Modular Smithery

Build tools from interchangeable material parts in a multiblock forge.
Inspired by the classics. Rebuilt from the ground up for modern Minecraft.

The lists below represent what's implemented today. Many more materials, modifiers, synergies, and alloys are actively being added. Expect frequent updates!

What is Smithery?

Smithery is a modular tool crafting mod for NeoForge. Smelt raw materials in a multiblock Forge, alloy them into advanced metals, cast them into parts, and assemble those parts into fully customizable tools and armor at a crafting table.

Every tool is made from interchangeable, material-specific parts — pair an iron blade with a copper guard and a gold handle, and each part contributes its own stats, modifiers, and visuals. No two tools need to be the same.

Core Features

Multiblock Forge

Build a fully enclosed Forge from Furnace Bricks, a Forge Controller, Fuel Ports, and Drains. No fixed blueprint — design any shape you want. The interior volume determines your fluid capacity (1,000 mB per air block).

• Open-top or closed-top — closed top gives 20% faster heating and 20% slower cooling
• Partial builds still work — the forge operates as the largest valid sub-structure it can find
• Temperature simulation — realistic heat-up, cool-down, and thermal mass (a full forge holds heat longer)
• Lava-fueled with RF coil support planned

Mixed-Material Tools

Assemble tools from distinct material parts. Each part carries its own durability, damage, speed, and harvest level into the final tool.

8 Tool Types:

4 Armor Pieces (Helmet, Chestplate, Leggings, Boots) each assembled from a Core + Plates + Trim.

21+ Materials

Every material has unique stats, modifiers, and visual tinting — all auto-generated at runtime.

Per-Material, Per-Tool Modifiers

Materials don't just change stats — they grant unique abilities depending on which tool they're used in:

Material Synergies

Combine specific materials across parts to unlock bonus modifiers at no slot cost:

Anvil-Applied Modifiers

Upgrade your tools further at the vanilla Anvil using special items:

Modifier slot count is determined by your Binder material: Iron = 2 slots, Gold = 3, Netherite = 4, Bedrock = 5.

Alloy System

The forge automatically alloys fluids when the right ratios and temperatures are met:

Two Part-Production Paths

Every material knows which path it belongs to. No overlap, no shortcuts.

Machinery & Blocks

Runtime Asset Generation

Every registered material automatically generates:

• Molten fluid + bucket
• All applicable tool parts (tinted per material)
• Casting recipes, smelting recipes, melting recipes
• Item models and lang entries

Zero boilerplate JSON per material. Register a material in Java and everything else follows.

For Modders

Smithery is built from the ground up to be modder-friendly:

• Java Builder API — register materials, parts, tool types, modifiers, synergies, and alloys with clean builder syntax
• ForgeMobDrops API — map any entity class to a fluid for forge mob processing
• JSON Modifier System — define new modifiers entirely in data packs using 9 built-in action types
• Datapack Overrides — all recipes and balance parameters are data-overridable
• No boilerplate — runtime generation handles models, textures, items, and recipes automatically
