This module adds the ability to create custom armor enchantments.


Metallurgy adds new custom ores, obsidian casts, and enchantments called shamirs.

Custom Ores

Custom ores can be found within different types of stone. To uncover custom ores, stone must be blown up with TNT. After the blast, a few lumps of metal will drop in the blown up area. The following ores can be found in each of the listed types of stone below.

Blowing up stone for metal lumps
Stone Type Ore Metal
Stone Malachite Lump Copper
Granite Baryte Lump Barium
Diorite Thorianite Lump Thorium
Andesite Bauxite Lump Aluminium

When a thorianite lump is in the inventory, the player will experience a mining fatigue effect.

Molds and Casting

Molds are used to create Obsidian Casts. A mold can be created by dropping one obsidian and one clay ball onto a sand block.

Creating a mold

To start casting metals, the mold must first be heated by placing lava over it. However, if a mold is heated for too long, it will break and drop as a magma block. When a mold is overheated, it will ignite a 3x3 area around it and the sand will be replaced with a small amount of lava.

Overheating a mold

Over time, a mold will cool down if it's not being heated by lava. When it cools down completely, the obsidian will drop as an item, or as an Obsidian Cast if there is metal inside it.

When the mold is heated and glowing red, metals can be added. When the mold cools down, it'll eventually stop accepting metals. The mold must be reheated to continue adding metals. A total of 23 custom ores are required to create a proper obsidian cast. If an incorrect number of metals are added, the obsidian band will be created with a Mundane Band which is completely useless.

Adding metal to a mold

Obsidian Casts

There are 6 types of Obsidian Casts: 4 made of pure metals and 2 made of alloys. Below is a list of the metals required for each band type. If cast incorrectly, a mundane band will appear on the obsidian cast. Mining a cast breaks the metal band on it, so if an obsidian cast is placed and broken, it will drop with a Mundane Band.

Metal Properties

Each of the six metals hold a specific property. The six metals are split into two groups with two metals having opposing properties and their alloy acting as the balance between the two. Each shamir will have a property relating to their metal property. Below is a list of each metal property.

Metal Group 1
Metal Property Description
Copper Creation Creating items, mobs or other entities from nothing e.g. XP doublers or extra item drops.
Thorium Brass (alloy) Equivalence Something that converts something from one state to another or destroys one thing to create another e.g. block swappers or item converters.
Thorium Destruction Something that damages or destroys e.g. melee attacks, block breakers, explosions. If it consumes fuel it is still destruction not equivalence.
Metal Group 2
Metal Property Description
Barium Amplification Increases the effect of an entity e.g. increases health, duplicates an action e.g. chain block breaking or increases player awareness e.g. ore highlighting.
Barimium (alloy) Modification Adds a new property to an entity e.g. potion effect, changes the outcome of an effect e.g. an attack that heals or modifies an existing property in a way that is neither positive or negative e.g. renaming a mob.
Aluminium Supression Decreases the effect of an entity e.g. decreases health, dampens or stops an existing property e.g. stops creepers exploding or limits the player's awareness e.g. mining fatigue or slowness.


An obsidian cast with a metal band will contain a shamir. A shamir is essentially a custom enchantment which appears on an obsidian cast's metal band. Each shamir can only be put onto specific items, shown in the table below.

By default, there are 13 shamirs, but expansion packs can add other shamirs. Shamirs on the same metal will each have an equal chance of appearing with that metal when a cast is created. For more information about each shamir, click on its name to go to the shamir's page.

Default Expansions

Metal Band Shamir Name Can Be Placed On Effect Limitation
Aluminium Defuse Armor Prevents creeper explosions The creeper can no longer ignite or explode naturally afterwards
Helios Armor Negates weighted armor by one slowness level Withering and levitation if not enough weight to hold you down
Levity Boots Sneak to hover; no fall damage after levitating Shot upwards if damaged; Bows and other projectiles will not work properly; Not infinite
Barium Arborenda Axes Chops all logs above the one broken by the player N/A
Sensus Compass Plays sounds from nearby ores N/A
Barimium Gemini Hoe Hold in the off hand when breeding animals to produce twins N/A
Musical Swords Grants strength I and plays music while killing mobs. With more kills, the music will become darker, and will grant strength II. Grants slowness at the same level as the strength bonus.
Copper Forterra Pickaxe Iron nuggets, gold nuggets, and redstone dust can drop from mined stone Cannot be combined with silk touch
Hypexperia Tools and Weapons Grants extra experience Cannot be combined with silk touch (mining with silk touch doesn't initially give exp)
Thorium Conduction Iron Sword and Iron Axe Strikes blocks with lightning If not enough damage is dealt by the time the volt timer runs out, it will strike the user instead
Ender Bolt Swords and Trident Withers nearby mobs Cannot affect players, armour stands, or "non-living" entities
Thorium Brass Spiraculum Bucket Attracts mobs like a vacuum Cannot fill the bucket with liquid
Tinker Tools Converts certain items in your inventory from individual items to blocks (e.g. diamond -> diamond block) Cannot be placed onto an axe; items will only convert if in a stack of 64

Attaching and Detaching Bands

In order for a shamir to be active, it must be put onto an item. Whilst on the band, the properties are contained and does not do anything. Shamirs can only be placed on certain items, similar to how vanilla enchantments are limited to certain items.

To transfer the band off the obsidian cast and onto an item, place an anvil with a downwards facing piston two blocks above it, leaving an air gap between the anvil and piston. Throw the obsidian cast and a valid item onto the anvil, then power the piston. The piston will remove the metal band from the obsidian and the item will gain the shamir properties. Only one Shamir can be placed on an item. If the item already has a shamir, the process of attaching another band will fail.

Attaching the Defuse shamir onto a chestplate

To transfer an item's shamir back to a cast, drop the item and a piece of obsidian (doesn't have to be an empty cast) on to the anvil, and power the piston again. The piston will transfer the shamir from the item onto the obsidian.

Expansion Packs

Additional expansion packs add new shamirs that work with the base system. Additional expansion packs can be created and submitted to GM4, such as those listed below. To find what each shamir does in more detail, click the corresponding name in the table below. When an expansion pack is installed, the shamir will have an equal chance as the other shamirs on the same band of being selected. For more information about each shamir, click on its name to go to the shamir's page.

Other Expansions

Metal Band Shamir Name Can Be Placed On Effect Limitation
Aluminium Moneo Tools Warns the player when their tool is low on durability and slows mining speed Players can still break their tool if they ignore the warnings
Thorium Brass Percurro Weapons Teleports the player forward, behind their target Players will be teleported to a safe location and may not travel the complete distance
