Warning: Psi Requires Patchouli for 1.16.5 and more recent versions. Older versions require AutoRegLib
Psi is a magical tech spell programming mod inspired by Mahouka Kokou no Rettousei. Don't worry if that doesn't make any sense.
The core of Psi is a system where you can create action sequences ("Spells") to be executed in the world. This system is followed by a leveling system containing ingame documentation and tutorials of the various concepts and pieces you'll get. The mod makes use of basic mathematical concepts, such as Vectors in its systems, which allows for great flexibility on what spells can do.
Psi spells can be shared and copied to and from outside sources, using ingame sharing tools. The main repository for user made psi spells is the Psi Spell Compendium on reddit.

Massive thank you to panda885 for doing the work on getting this almost up to speed on 1.19.2
- Important Info**:
This port was almost entirely done by Dudblockman on his free time over the last few months. I (Vazkii) only came in at the last moment to patch up the build script and get it released. All credit here should go to Dud.
This version will *not* be supported actively, as immediately after the release, I will begin porting the mod to 1.19.2. It's purely being released because well, it exists, so I figured some people would be interested in having it. The build was reasonably tested and should work perfectly fine as far as I'm aware, but I can make no promises, it's released as Beta, and I advise you to use it at your own risk.
With that said, I think the pitiful state of the mod's documentation needs to be addressed. Around the time of the migration, Alwinfy began rewriting the original tutorial system to be available in a Patchouli book with a less awful UI. You may know Alwinfy as the one who rewrote the entire Lexica Botania, which should be proof enough they're capable of handling the job.
Alas, due to lack of motivation, Dud's slow pace, and little reception from Psi's highly niche community, this rewrite was never finished, and the bits that were, were never properly polished - this is immediately evident when you open the guide book ingame.
As I'm taking over the project again temporarily, I'll work alongside Alwinfy to ensure the documentation is complete and fully working for 1.19.2, which may make that port take slightly longer, but definitely not as long as the 1.18.2 move.
Thank you for your patience, and I hope you enjoy Psi in modern versions.

- Updated to 1.18.2
