Destruction is one of the basic impulses of Fire, and this spell calls on that urge to spread destruction in the caster's surroundings. The spell whips the kami into a frenetic chaos, destroying everything around you. everyone in the area of effect, including you, suffers damage with DR equal to your Fire Ring. This result is rolled once and applied to everyone within the area - however, you take only half damage (rounded up), since the kami do make some effort to avoid you.
