Benefit: Members of this race have a fly speed of 30 feet

Benefit: Choose a dragon at character creation Then pick either a 15-foot cone or a 20-foot line. Once per day, as a standard action, members of this race can make a supernatural breath weapon attack that deals 1d6 + 1d6 per 2 levels of the damage of the dragon's breath weapon. All creatures within the affected area must make a Reflex saving throw to avoid taking damage. The save DC against this breath weapon is 10 + 1/2 the user’s character level + the user’s Constitution modifier. Those who succeed at the save take no damage from the attack
