Breath Weapon (Su): An ectoplasmic dragon has one breath weapon: a burst of whitefire. The radius and range of the breath weapon are listed in the chart. They spit out a glob of raw ectoplasm that explodes upon reaching the desired range.

* Though ectoplasmic dragons cannot be smaller than Medium, these sizes were included for completeness.

Planar Travel (Su): Ectoplasmic dragons have the innate ability to pass instantly between the Material Plane and the Astral Plane as a standard action.

Psionics (Sp): 3/day -- chameleon, dismiss ectoplasm, ectoplasmic cocoon, negate psionics; 2/day -- energy barrier; 1/day -- catapsi, mass cocoon. Manifester level varies by age; save DC 10 + dragon's Intelligence modifier + power level. An ectoplasmic dragon manifests powers and gains additional attack and defense modes as if it were a psion with Metacreativity as its primary discipline.

Attack/Defense Modes: Id insinuation/mental barrier.

Whitefire Aura (Su): The ectoplasmic dragon can initiate its whitefire aura once per day as a standard action. It lasts 1 round per age category of the dragon. While the aura lasts, any creature striking the dragon with a natural or a handheld weapon deals normal damage, but at the same time the attacker takes the whitefire damage listed. If the attacker makes a successful Reflex save (DC same as frightful presence), it reduces damage by half.

Ectoplasm Immunity (Ex): An ectoplasmic dragon is not effected by the dismiss ectoplasm power.

Fire Subtype

A creature with the fire subtype has immunity to fire. It has vulnerability to cold, which means it takes half again as much (+50%) damage as normal from cold, regardless of whether a saving throw is allowed, or if the save is a success or failure.
