Frequently asked questions

How do I get started with the Psi mod?
Craft a CAD Assembler, then use it to combine a CAD Assembly, a CAD Core, a CAD Battery, and a CAD Socket into a Casting Assistant Device (CAD). You'll also need a Spell Programmer to write and store spells on a Spell Drive.
How do I craft a Spell Programmer?
The Spell Programmer is a placeable block crafted via a shaped recipe. Place it down and interact with it to open the spell-writing interface.
How do I make a CAD?
Use the CAD Assembler block to combine a CAD Assembly, a CAD Core, a CAD Battery, and a CAD Socket. The specific core, battery, and socket you choose determine the CAD's stats and behavior.
What's the difference between CAD Cores?
Available cores include Basic, Conductive, Hyperclocked, Overclocked, and Radiative CAD Cores. Each core affects how your CAD handles spell complexity and casting speed.
What CAD Batteries are available?
Basic, Extended, and Ultradense CAD Batteries exist. Higher-tier batteries store more Psi energy for casting spells.
What CAD Sockets can I use?
Basic, Large, Huge, Signaling, and Transmissive CAD Sockets are available. The socket type determines how many Spell Bullets the CAD can hold and how it interacts with the world.
How do I write a spell?
Use the Spell Programmer block to assemble spell pieces into a program, then save it to a Spell Drive. Insert the Spell Drive into your CAD to cast the stored spell.
What are Spell Bullets for?
Spell Bullets are ammunition loaded into a CAD's socket. Types include Charge, Circle, Grenade, Loopcast, Mine, Projectile, and the plain Spell Bullet, each changing how the spell fires.
How do I upgrade a Spell Bullet?
Use the psi:bullet_upgrade recipe type, typically performed in the Spell Programmer or CAD interface, to convert a basic Spell Bullet into a specialized variant like Grenade or Projectile.
How do I make Psimetal?
Smelt or process Ebony Substance and Ivory Substance to obtain Ebony Psimetal Ingots and Ivory Psimetal Ingots. These ingots can be crafted into Psimetal Ingots and Psimetal Blocks.
What can I craft from Psimetal Ingots?
Psimetal Ingots are used to craft Psimetal tools (Axe, Pickaxe, Shovel, Sword) and the Psimetal Exosuit armor set (Helmet, Chestplate, Leggings, Boots).
How do I use the Psimetal Exosuit?
Craft and equip the Psimetal Exosuit armor pieces, then install an Exosuit Controller and sensors (Heat, Light, Stress, Water, Detonation) to enable environmental detection and spell triggers.
