It's not an option you turn on or off. It's not something you can do for more power. It's intrinsic to the nature of the world. Arcane magic is life-force. If you want to cast a fireball, you will kill things around you, or gradually kill yourself.
What? This is incorrect.
There was no "kill yourself." There was a "draw magic from things around you slowly and carefully so as not to harm them," which was what Preserver was, which was exactly equal to a standard wizard in D&D.
