Your draconic heritage stems from a mighty, primordial linnorm rather than from the more common, somewhat civilized dragons.

Associated Bloodline: Draconic.

Bloodline Arcana

Whenever you cast a spell with an energy descriptor that matches your linnorm bloodline’s energy type, you gain a natural armor bonus equal to the spell’s level for 1d4 rounds.

This ability replaces the Draconic Bloodline Arcana.

Bloodline Powers

True dragons blast their foes with rays of energy.

Elemental Spit (Su): Starting at 1st level, you can fire an elemental ray that matches your linnorm bloodline’s energy type as a standard action, targeting any foe within 30 feet as a ranged touch attack. The ray deals 1d6 points of damage + 1 for every two sorcerer levels you possess. You can use this ability a number of times per day equal to 3 + your Charisma modifier.

This bloodline power replaces claws.
