Psi

Psi is a mod created by Vazkii. It is themed around magical programming, being inspired by the Japanese web novel and anime Mahouka Koukou no Rettousei.

Psi allows action sequences, or spells, to be both created and executed in the Minecraft world. It allows leveling out, and many of the programming done requires the use of mathematics. Spells are created in the Spell Programmer, which has a drag-and-drop interface, but is still nevertheless complicated.
