Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader

Minecraft version

⬇ Download for 1.21.1 · NeoForge⬇ Download for 1.20.1 · Forge
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Psi: Tweaks And Additions

PsiTweaks is an addon mod that expands the magical programming mod Psi, providing a deeper experience and extending its progression well into the late game.

It adds numerous spell pieces, new programming types, higher-tier CADs and spell bullets, casting-support equipment, a research system, and various quality-of-life improvements. When Mekanism is installed, players can also access industrial production methods for Psi materials, dedicated machines, and MekaSuit modules.

Documentation for these features is included in the in-game Encyclopaedia Psionica through Patchouli.

Main Features

Expanded Spell Programming

In addition to straightforward offensive spells, these features allow you to create complex spells that work with item and block data, as well as programs designed for automation.

CADs, Spell Bullets, and Equipment

Higher-tier equipment makes it practical to use large-scale, high-cost spells that would be difficult to handle with standard Psi equipment.

Mekanism Integration

PsiTweaks strongly recommends installing Mekanism and adds various features that connect Psi progression with industrial machinery.

When Mekanism is not installed, Mekanism-specific machines and modules are not added. Alternative recipes are provided for certain materials and research programs.

Special thanks to Vazkii, the creator of Psi, and bradyaidanc, the creator of Mekanism.

Some elements of this mod were inspired by or make use of ideas from PlusTiC Reforged by queengooborg, Random PSIdeas by kamefrede123, and Psionic Peripherals by Dudblockman. I would also like to extend my sincere thanks to their creators.
