Alternate Form (Su): An iron dragon can assume any animal or humanoid form of Medium size or smaller as a standard action three times per day. The dragon can remain in its animal or humanoid form until it chooses to assume a new one or return to its natural form.
Metalsense (Ex): all ferrous dragons can sense the location and amount of any non-precious metal (precious metals include adamantine, copper, gold, mithral, platinum, and silver) within a distance of 30 feet x the dragon's age category. This makes it nearly impossible to sneak on a ferrous dragon when wearing armor or wielding weapons made of iron or other nonprecious metals. Like blindsense, opponents the dragon can't actually see still have total concealment against the dragon.
Breath Weapon (Su): An iron dragon has two types of breath weapon, a cone of superheated sparks (dealing half electricity and half fire damage), and a cone of sleep gas. Creatures within a cone of sleep gas must succeed on a Will save or fall asleep, regardless of HD, for 1d6 rounds plus 1 round per age category of the dragon.
Spell-like Abilities: 3/day - heat metal.
Skills: Disguise, Gather Information, and Jump are considered class skills for iron 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.
