Breath Weapon (Su): A tungsten dragon has one type of breath weapon, a cone of blasting sand that deals half bludgeoning damage and half fire damage.

Immolation (Su): Once per day a great wyrm tungsten dragon can target up to three creatures within a 30 feet per age category with an immolation attack. The targets immediately burst into flames, taking 6d6 points of fire damage. Additionally, targets catch fire, taking an additional 2d6 points of fire damage each round until the flames are extinguished. A successful Fortitude save halves the damage and prevents the target from catching on fire. The save DC is Charisma-based.

Sand Cloud (Sp): This ability is similar to a fog cloud spell but with swirling sand instead of fog. These fine grains of sand smother unprotected flames and can even choke protected flames (50% chance). The swirling sand also makes it difficult to cast spells. Casters within a sand cloud must succeed at a Concentration check or the spell is lost (DC 15 + spell level). An old or older tungsten dragon can use this ability twice per day. This ability is the equivalent of a 3rd-level spell.

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.

Spell-Like Abilities: 1/day - discern lies.

Skills: Gather Information, Spellcraft, and Survival are considered class skills for tungsten dragons.

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.
