Thaumcraft Mod Wiki

Thaumcraft, created by Azanor, is a magic mod built around the idea of thaumaturgy: drawing magical power from the physical and mystical "aspects" that make up everything in the world. Players study these aspects by scanning blocks, items, and creatures, gradually unlocking research that grants access to new tools, machines, and abilities.

Progression begins by sprinkling Salis Mundus on a Crafting Table to create an Arcane Workbench, then crafting a Thaumometer to scan the world. Scanning reveals the aspects contained in objects and grants observation points, which feed a research minigame at the Research Table and slowly fill out the Thaumonomicon, the mod's in-game guidebook.

The mod is organized into several research branches, each focused on a different style of magic: harnessing raw magical energy, alchemy, enchanting equipment, large-scale infusion crafting, building autonomous golems, and exploring dangerous eldritch knowledge.

Everything in Thaumcraft is described by aspects, the fundamental building blocks of magic. The primal aspects include Aer (air), Terra (earth), Ignis (fire), Aqua (water), Ordo (order), Perditio (entropy), and the magical aspects Praecantatio and Vacuos. More complex objects are made of combinations of these aspects.

Vis is the ambient magical energy stored in the aura of each chunk of the world. Casting spells and performing magical crafting draws vis from the local aura, which depletes with use and slowly regenerates over time. When an aura runs low, magic in that area becomes less effective.

Essentia is the liquid, concentrated form of aspects, extracted from items. Essentia is stored in jars and phials and moved through an essentia transport network. Players distill items into essentia and then recombine specific aspects to power alchemy and infusion recipes.

Knowledge in Thaumcraft is gated behind research. Scanning blocks, mobs, and items with the Thaumometer earns observation points and reveals aspects. At the Research Table, players spend these points on a theorycraft minigame, connecting aspects to complete research notes and unlock new entries.

Unlocked knowledge is recorded in the Thaumonomicon, which is divided into branches such as:

• Fundamentals - basic tools, scanning, and vis crystals.
• Auromancy - channeling vis directly through the Caster's Gauntlet and its foci.
• Alchemy - distilling essentia and producing items like Nitor and alchemical salts.
• Artifice - enchanted equipment, baubles, and magical devices.
• Arcane Infusion - high-tier crafting using the Infusion Altar.
• Golemancy - constructing and commanding golems.
• Eldritch - dangerous, warp-gated knowledge involving flux, taint, and cultists.

Research must generally be unlocked in order, so players progress from simple scanning toward advanced infusion and eldritch magic.

Alchemy turns items into usable magical materials. The Crucible distills items dropped into boiling water down into liquid essentia, while the Arcane Alembic captures and processes the resulting aspects. From these, players produce items such as Nitor (a magical light source) and various salts and potions.

Essentia is then moved and stored through a transport network:

• Essentia Tubes carry essentia between blocks, with directional, filtered, and restricted variants for control.
• Warded Jars and Void Jars store essentia, the void variant voiding overflow.
• Essentia Buffer, Valve, and Centrifuge store, regulate, and separate essentia.
• Essentia Transfuser fills and empties essentia containers.
• Essentia Smeltery variants smelt items in bulk into essentia.

This network lets players automate the supply of specific aspects to their alchemy and infusion setups.

Arcane Infusion is the mod's high-tier crafting system, used to make its most powerful items. The player builds a multiblock structure consisting of a central Infusion Altar (Runic Matrix) surrounded by Arcane Pedestals holding the crafting ingredients.

During infusion, essentia is drawn from nearby jars and the surrounding components, and the recipe slowly assembles over several seconds. Infusion generates instability, which can cause harmful side effects, lightning, or item loss if it climbs too high. Players reduce instability by surrounding the altar with Stabilizer blocks, candles, skulls, and Redstone Inlay arrangements. Infusion Cost and Infusion Speed stones can further tune the process.

Successful infusion is required for advanced armor, weapons, and devices throughout the mod.

Golemancy lets players build small autonomous helpers called golems. A golem is assembled with a Golem Press and given a mind core that determines its capabilities, such as the Clockwork Mind (mechanical) or Biothaumic Mind (organic).

Golems are assigned jobs using Seals, placed in the world and directed with the Golemancer's Bell. Seal types cover a wide range of automation tasks, including:

• Harvest and Lumberjack - farm crops and chop trees.
• Collect and Store - gather items and place them into storage.
• Block Breaker and Use - mine blocks and perform actions.
• Butcher and Guard - kill or protect mobs.
• Fill/Empty, Provide, and Stock - manage tanks and inventories.

Many seals have advanced variants with greater range or filtering, letting golems handle increasingly complex automation.

Spellcasting is handled by the Caster's Gauntlet, which draws vis directly from the chunk aura and casts spells defined by interchangeable Foci (Blank Lesser, Advanced, and Greater Focus being the upgradeable bases). This replaces the older wand system, so power comes from the surrounding aura rather than charges stored in the tool.

The mod adds full tool and weapon sets made from its special metals, Thaumium and Void Metal, including pickaxes, axes, shovels, hoes, and swords, with the Void variants being stronger and self-repairing. It also adds many special weapons and tools, such as:

• Sword of the Zephyr and Axe of the Stream - area-effect melee weapons.
• Primal Crusher - a powerful multi-tool hammer.
• Pickaxe of the Core and Shovel of the Earthmover - mass-mining tools.
• Hoe of Growth - accelerates crops.
• Arcane Grappler - a grappling hook for mobility.
• Magic Mirror and Hand Mirror - linked item-teleportation devices.

Thaumcraft adds several armor sets with magical properties, including Thaumium Armor, the heavier Thaumium Fortress Armor, high-tier Void Armor, and lightweight caster outfits such as the Thaumaturge's Robes and Void Thaumaturge Robes. The Goggles of Revealing allow the wearer to see aspects and magical auras in the world, and Boots of the Traveller improve movement.

Using the Baubles system, players can equip magical accessories in dedicated slots:

• Amulet of Vis and Vis Stone - increase vis capacity and storage.
• Charm of Undying - protects the wearer from a fatal blow.
• Cloudstepper Ring and Apprentice's Ring - movement and utility.
• Headband of Curiosity - speeds up research.
• Verdant Heart Charm and Voidseer's Pearl - nature affinity and eldritch sensitivity.

These accessories provide passive bonuses that complement a thaumaturge's tools and armor.

Using magic is not without consequence. Spell failures and crafting instability generate flux, polluted magical energy that builds up in the aura. Flux Condensers capture and process flux before it becomes a problem; if flux is left unchecked it spreads as Taint, corrupting the landscape.

Taint manifests as blocks like Tainted Soil, Tainted Rock, Crusted Taint, and Swollen Taint, along with Taint Geysers that erupt and Fibrous Taint plants. Tainted biomes are hostile to ordinary life.

Warp is a measure of how much forbidden knowledge a thaumaturge has absorbed. Deep exploration, eldritch research, and dangerous items raise warp, which unlocks the Eldritch research branch but also inflicts negative effects, hallucinations, and visual distortions. Eldritch content includes ancient stone structures, the Crimson Cult and their cultists, Void Seeds, and other high-risk, high-reward magic.
