Glib Lie (Su)

Amaster spy of 2nd level or higher can deceive truth-detecting magic. A creature using this sort of magic against the spy must succeed on a caster level check against a DC of 15 + the master spy’s class level to succeed (as if she were under the effect of a glibness spell); failure means the magic doesn’t detect the spy’s lies or force her to speak only the truth. This ability does not give the master spy the glibness spell’s bonus on Bluff checks.
