Rock Throwing (Ex): The range increment is 120 feet for this draconic fire giant's thrown rocks. The creature can hurl rocks weighing 40 to 50 pounds each (Small objects) up to five range increments.

Rock Catching (Ex): This giant can catch Small, Medium, or Large rocks (or projectiles of similar shape). Once per round, if the creature would normally be hit by a rock, it can make a Retlex save to catch the projectile as a free action. The DC is 15 for a Small rock, 20 for a Medium one, and 25 for a Large one. (If the projectile has a magical bonus on attack rolls, the DC increases by that amount.) The giant must be ready for and aware of the attack.

Save Bonuses (Ex): This draconic fire giant has a +4 bonus on saves against magic sleep and paralysis effects.

Draconic fire giants fight much like their giant brethren, relying either on a greatsword or on thrown boulders heated by volcanic fire.

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.
