Breath Weapon (Su): A gold dragon has two forms of breath weapon, a cone of fire (16d10 damage, Reflex save for half damage DC 31) or a cone of weakening gas. Creatures within the latter must succeed at a Fortitude save (DC 31) or take 8 points of temporary Strength damage. Using a breath weapon is a standard action. Once a dragon breathes, it can't breathe again until 1d4 rounds later. If the dragon has more than one type of breath weapon, it still can breathe only once every 1d4 rounds. A blast from a breath weapon always starts at the dragon's mouth and extends in a direction of the dragon's choice.
Alternate Form(Su): A gold dragon can assume any animal or humanoid form of Medium size or smaller as a standard action three times per day. A dragon can remain in its animal or humanoid form until it wishes to assume a new one or return to its natural form. A true seeing spell or ability reveals the creature's natural form. A creature using alternate form reverts to its natural form when killed, but separated body parts retain their shape. A creature cannot use alternate form to take the form of a creature with a template.
Fire Subtype (Ex): Fire immunity, double damage from cold except on a successful save.
Water Breathing (Ex): The dragon can breathe underwater indefinitely and can freely use its breath weapon, spells, and other abilities while submerged (the cone of fire becomes a cone of superheated steam underwater).
Frightful Presence (Ex): A young adult or older 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 240 feet are subject to the effect if they have fewer HD than the dragon (29).
A potentially affected creature that succeeds at a Will save (DC 31) 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.
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.
