Shoot daggers at everything in a cone

You emit a storm of swords. Make a single ranged attack roll. Each creature in the area whose armor class is less or equal to your attack roll is hit by one sword per caster level (max 10). Each sword counts as a magical +1 piercing weapon, with 1d10 base damage and 19-20/x2 crit. Damage reduction is applied to each sword separately. Bonus damage for example from sneak attacks, critical hits or other sources is applied to the first sword only.
