The caster begins to run at a speed equal to that of light. To bystanders, he seems to vanish into thin air, but in reality he sprints at incredible speed, perceiving his surroundings as if he were merely running fast. It is possible for the caster to run over any walkable terrain, for example, he can cross an entire continent in the time of a blink of an eye. It is not possible for him to perform any other action while running.
The spell lasts for one second.
