Astral prison

With power comes responsibility... or so they say. All you know is that you can create an astral prison made out of some kind of crystal. The best part about this thing is that it shrinks, kills your victim, and traps the soul!!! HAHAHAHA! It gets better!!! Not only does it trap the soul, kill the victim, and make you laugh... you can suck magical energy off the soul and it decreases the cost of casting spells! HA!

The crystal with the trapped soul is conveniently floating nearby but it is indeed fragile. It won't last long, so make good use of it!

Syntax: cast 'astral prison'

Prerequisites: immolation
