Breath Weapon (Su): A sapphire dragon breathes a cone of nearly inaudible sonic energy. In addition to making a Reflex saving throw (DC 17) against sonic damage (6d4), each creature within the cone must succeed at a Will save (same DC) or become panicked 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.

Dragons ignore the frightful presence of other dragons.

Earth Subtype
