A Magic System for Fate
(For Fate Core, Fate Accelerated, Fate Condensed)
Magic is potential. Until it is shaped and given physical form, is is only ever potential. The act of “casting” is the act of giving form to magic. Whether it be the blast of ice of an ice-ball or the fundamental changes in the chemistry of the brain that makes someone predisposed to like you, casting magic is the application of will to make changes to the physical world.
There are Fundamental Laws and Practical Laws. Fundamental Laws detail simply how magic works. These cannot be changed. Practical Laws are social constructs (usually) observed because the potential consequences are devastating.
