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 17) takes 6d6 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.

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).
