Protection from Arrows

The damage reduction increases to 15/magic. The maximum damage prevented by the spell increases to 15 points per caster level (maximum 150 points). If the spell prevents all damage from a ranged weapon attack, it turns the projectile or weapon back on the attacker, using the same attack roll result. If the attacker is also protected by mythic protection from arrows and its spell completely prevents the damage from the rebounded attack, the weapon or projectile is destroyed.
