At 1st level, you can draw upon your outsider heritage to spin amazingly convincing lies. Activating this ability is a swift action. You gain a +5 bonus on one Bluff check made to convince another of the truth of your words (similar to using glibness). If a magical effect is used against you that would detect your lies or force you to speak the truth, the user of the effect must succeed on a caster level check (DC 10 + your sorcerer level) to succeed. Failure means the effect does not detect your lies or force you to speak only the truth. You can use this ability a number of times per day equal to 3 + your Charisma modifier.
