Psi Unofficial
Minecraft Java mod. Downloads from the MC Java Mods app on Android.
⬇ Download on CurseForgePsi is a mod about spell programming, inspired by Mahouka. It's still in development but it's not in 1.12.2. Original version has some issues and can be better, so this is the reason why i created this fork.
For now:
- Fixes custom recipes not working
About license:
The license allows me to use, share and adapt the mod
- Original author is Vazkii not me, i'm just here to make 1.12.2 version better, this is not an official fork, so don't bother vazkii about this fork.
- I don't get any money from this fork.
Check out the PSI official website for more info:
