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.
| Dragon Size* | Maximum Range | Radius |
| Tiny* | 30 feet | 5 feet |
| Small* | 40 feet | 10 feet |
| Medium | 60 feet | 15 feet |
| Large | 80 feet | 20 feet |
| Huge | 100 feet | 25 feet |
| Gargantuan | 120 feet | 30 feet |
| Colossal | 140 feet | 35 feet |
* 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.
