About this project

What does Modular Smithery add?

Smithery

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

Available for NeoForge (Minecraft 26.1.2) and Forge (Minecraft 1.20.1) — same gameplay and balance on both.

What is Smithery?

Smithery replaces "three sticks and two ingots" with a proper smithing craft. You build a multiblock Forge in any shape you like, melt down raw materials inside it, and turn the molten metal into tool parts — then assemble those parts into tools and armor where every part matters.

An iron blade with a gold handle and a copper binder isn't just a skin: each material carries its own stats and special abilities into the finished tool, and certain material combinations unlock bonus effects on top. No two tools need to be the same.

The Loop

Build a Forge from furnace bricks, a controller, a fuel port, and a drain — any shape, open- or closed-top. Bigger forges hold more molten metal; partially built ones still work at whatever size is properly walled in.
Melt things down. Toss in ore, ingots, or gear — anything meltable becomes molten fluid. The forge alloys compatible metals on its own, and yes, it will happily melt mobs.
Cast your parts. Impress a part shape into casting sand, then a single redstone pulse at the drain pours exactly the metal your cast needs. Wood, flint, slime, and other non-meltables get cut on the redstone-driven Part Press instead.
Assemble at the crafting table. Combine parts freely — blade, guard, handle, binder — into swords, pickaxes, bows, spears, armor, and more.
Keep upgrading. Materials grant built-in abilities, cross-material synergies add free bonuses, and the vanilla anvil applies further modifiers as your tool grows with you.

Dependencies

	NeoForge (26.1.2)	Forge (1.20.1)
Required	GeckoLib 5+	GeckoLib 4.8+
Optional — in-game field guide	Modonomicon	Patchouli
Optional — recipe browsing	JEI	JEI 15+

Without the optional mods Smithery runs normally — you just lose the field guide book or the in-game recipe browser.

For Modders & Pack Makers

Smithery is built to be extended: new materials, parts, tool types, modifiers, and alloys register through a clean Java API, with textures, models, items, and recipes generated automatically at runtime — no boilerplate. Recipes and balance are datapack-overridable, and JEI shows every melting, casting, pressing, and assembly recipe in game.
