The sanctified red dragon's natural weapons, and any weapons it wields, are considered good weapons for purpose of overcoming damage reduction.

Breath Weapon (Su): 40-ft. cone, 4d10 fire, Reflex save DC 18.

Light Ray (Su): Once per round, as a standard action, the sanctified red dragon can fire a ray of searing light from its eyes. The ray is treated as a ranged touch attack and has a maximum range of 60 feet. Against evil creatures, the ray deals 5d6 points of damage. The light has no harmful effect on non-evil creatures.

Aura of Menace (Su): A righteous aura surrounds the sanctified red dragon. Any hostile creature within a 20-foot radius of it must make a DC 20 Will save to resist its effects. Those who fail take a -2 penalty on attacks, AC, and saves for one day or until they successfully hit the sanctified red dragon. A creature that has resisted or broken the effect cannot be affected again by this sanctified red dragon's aura for one day.

Magic Circle against Evil (Su): A magic circle against evil effect always surrounds the sanctified red dragon, as the magic circle against evil spell. Caster level 10th.

Tongues (Su): The very young red dragon can speak with any creature that has a language, as though using a tongues spell cast by 10th-level sorcerer. This ability is always active.

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.
