Monster Manual II
Breath Weapon (Su): A sapphire dragon breathes a cone of nearly inaudible sonic energy. In addition to making a Reflex saving throw (DC 24) against sonic damage (12d4), 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.
Frightful Presence (Ex): An 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 180 feet are subject to the effect if they have fewer HD than the dragon (20 HD).
A potentially affected creature that succeeds at a Will save (DC 23) remains immune to that dragon's frightful presence for one day. On a failure, creatures with 4 or fewer HD become panicked for 4d6 rounds and those with 5 or more HD become shaken for 4d6 rounds.
Dragons ignore the frightful presence of other dragons.
This subtype usually is used for elementals and outsiders with a connection to the Elemental Plane of Earth. Earth creatures usually have burrow speeds, and most earth creatures can burrow through solid rock.
