You warp a creature's truename to alter his perception.
Prerequisite: Truespeak 15 ranks, any recitation feat, ability to speak utterances, must know your own personal truename.
Benefit: You make the target confused, as the spell confusion, for 1 round. Even creatures immune to mind-affecting effects become confused. You must succeed on a Truespeak check to say your target's personal truename. The Truespeak DC to use this denouncement is 10 higher than normal.
