Sun Blow is an attack where the shaolin uses the power of the Sun to increase the damage dealt by a kick, punch, or other unarmed attack used as a base. During the day, when the Sun is up, the attack is 50% more powerful. Under clear sky the shaolin gets additional multiplicative +50% bonus as she can also use the faint but ever-present light of the stars which are just other suns. Interestingly enough, both those bonuses work even indoors or underground because they use the mystical aspect of Sun, not the actual physical sunlight.
