A stronger version of clap of thunder, an arctic blast spell is a mighty burst of cold, churning arctic air that detonates with a quick clap of thunder and deals 1d6 points of subdual damage per caster level (maximum 10d6) to all creatures within the area, as well as causing deafness as per the blindness/deafness spell for 5 rounds per level.
In order to target the arctic blast, you point your finger and determine the range (distance and height) at which the arctic air will burst forth. A small line of very cold air streaks from your finger and, unless it hits a material body or solid barrier prior to attaining the prescribed range, it then blossoms into the cold blast at that point. Like the fireball spell, to cast the line through an arrow slit, you must make a successful touch attack. The explosion of arctic air is also accompanied by a small shock wave. Against objects this works as an area attack, as per those rules for shatter.
Focus: A piece of ice or quartz.
