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 30) takes 18d6 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.
Crush: A flying or jumping dragon of at least Huge size can land on opponents as a standard action, using its whole body to crush them. Crush attacks are effective only against opponents three or more sizes smaller than the dragon (though it can attempt normal overrun or grapple attacks against larger opponents). A crush attack affects as many creatures as can fit under the dragon's body. Creatures in the affected area must succeed at a Reflex save against a DC 30 or be pinned, automatically taking bludgeoning damage during the next round unless the dragon moves off them. If the dragon chooses to maintain the pin, treat it as a normal grapple attack. Pinned opponents take crush damage each round if they don't escape.
Frightful Presence (Ex): A very old 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 270 feet are subject to the effect if they have fewer HD than the dragon (29 HD).
Air Subtype
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).
