Short description

Build machines from ordinary Minecraft blocks to automate farming, mining, smelting, and item transport. Server-side plugin; no client mod required.

Amethyst Runeworks

Build useful machines in your Minecraft world from familiar blocks. Watch them work, connect them with crystals, and grow from one small setup into an automation network.

Start with a geode

1. Find a full amethyst geode. Collect its amethyst blocks and crystal clusters. A complete geode should provide enough amethyst for your first machine; the wiki shows the other blocks you need. Leave budding amethyst in place so it can grow more crystals.
2. Build a Crystal Incubator. It is optional, but recommended for a steady supply of crystals for energy connections and item movement. Break harvested clusters into shards; four shards craft into an amethyst block.
3. Choose your next machine. Follow its 3D build plan, add the tool or supplies it needs, and turn its lever on. Use /arw guide for recipes and /arw inspect if a build is not recognized.

Grow & gather

Crystal Incubator

Grows amethyst crystals in a glass chamber using water and power.

Harvester

Plants and collects crops in automatic, replant, or harvest-only mode.

Fertilizer

Turns one bone meal into ten crop growth actions.

Lumber Cutter

Cuts a complete tree and replants a sapling.

Fluid Pump

Fills buckets from water, lava, or full lava cauldrons.

Mine & process

Quarry

Mines inside a closed redstone boundary using a pickaxe; better tools work faster.

Blast Furnace

Smelts ordinary furnace inputs and doubles supported ores and raw metals.

Power & defence

Burns fuel to make resonance for connected machines.

Network Battery

Stores spare resonance and supplies it when machines need power.

Magma Tower

Fires a crystal beam at hostile mobs and sets them on fire.

Lightning Tower

Charges up before striking hostile mobs.

Connect your machines

Amethyst carries energy. Link a generator, battery, and machines with facing crystals. See energy connections.

Lapis carries items. Crystal ports move items between connected containers and can filter item types or keep a chosen amount in stock. See item transport.
