Once the spell is made, it can be cast, either ``on the fly'' or from a Matrix. To cast the spell, the magician rolls their Path Skill based off the Attribute specified by their Discipline. For every 2 points MoS on the Skill Roll, subtract 1 point from Backlash. A magician who exhausts all Backlash collapses, remaining unconscious for 1 hour for each point they exceeded their maximum. When casting, magicians NEVER get Bonus Dice.
