Monster Manual II
Breath Weapon (Su): A crystal dragon's breath weapon is a cone of brilliant light. A target who fails his or her Reflex saving throw (DC 22) takes 10d6 damage and is blinded for 1d4 rounds. Using a breath weapon is a standard action. Once a dragon breathes, it can't breathe again until 1d4 rounds later. A blast from a breath weapon always starts at the dragon's mouth and extends in a direction of the dragon's choice.
Bite: The dragon also can use its bite snatch opponents. Bite attacks use the full attack bonus.
Claw: The dragon also can use its claws to snatch opponents. Claw attacks are at -5 to the attack bonus.
Wing: The dragon can slam opponents with its wings, even when flying. Wing attacks are at -5 to the attack bonus.
Tail Slap: The dragon can slap one opponent each round with its tail. A tail slap is at -5 to the attack bonus.
Frightful Presence (Ex): A young adult dragon can unsettle foes with its mere presence. The ability takes effect automatically whenever the dragon attacks, charges, or flies overhead. Creatures within a radius of 150 feet x the dragon's age category are subject to the effect if they have fewer HD than the dragon (17 HD).
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane Air. Air creatures always have fly speeds and usually have perfect maneuverability (see the section on Movement).
