Breath Weapon (Su): A pyroclastic dragon has two types of breath weapon, a cone of superheated ash accompanied by crushing waves of sonic force (dealing half fire damage and half sonic damage) or a disintegrating line. Creatures within the line must succeed at a Fortitude save or crumble to ash. (Creatures that successfully save do not take any damage.)

Extraplanar: This subtype can be applied to any creature on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. This listing assumes encounters with the fiendish dragons take place on the Material Plane. Every extraplanar creature in this listing has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game. If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures. On certain planes, called transitive planes, no creatures have the extraplanar subtype. The known transitive planes in the Great Wheel cosmology include the Astral Plane, the Ethereal Plane, and the Plane of Shadow.
Frightful Presence (Ex): A wyrmling pyroclastic 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 30 feet are subject to the effect if they have fewer HD than the dragon (7).
A potentially affected creature that succeeds at a Will save (DC 13) 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.
Immunities (Ex): All dragons are immune to sleep and paralysis effects. Pyroclastic dragons are also immune to fire and sonic effects.
Spell Resistance (Ex): As dragons age, they become more resistant to spells and spell-like abilities.
Blindsight (Ex): A dragon can ascertain creatures by non-visual means (mostly hearing and scent, but also by noticing vibration and other environmental clues) with a range of 30 feet.
Keen Senses (Ex): A dragon sees four times as well a human in low-light conditions and twice as well in normal light. It also has darkvision with a range of 100 feet and scent ability to 30 feet.
A subtype applied to any creature when it is on a plane other than its native plane. A creature that travels the planes can gain or lose this subtype as it goes from plane to plane. This book assumes that encounters with creatures take place on the Material Plane, and every creature whose native plane is not the Material Plane has the extraplanar subtype (but would not have when on its home plane). An extraplanar creatures usually has a home plane mentioned in its description. These home planes are taken from the Great Wheel cosmology of the D&D game (see Chapter 5 of the Dungeon Master's Guide). If your campaign uses a different cosmology, you will need to assign different home planes to extraplanar creatures.
Creatures not labeled as extraplanar are natives of the Material Plane, and they gain the extraplanar subtype if they leave the Material Plane. No creature has the extraplanar subtype when it is on a transitive plane; the transitive planes in the D&D cosmology are the Astral Plane, the Ethereal Plane, and the Plane of Shadow.
