Benefit

As a full-round action, you can belittle and insult a single creature that can understand you and is within 30 feet. You and the target must make opposed Intimidate checks; if you win, the target is humiliated and takes a -1 penalty on attack rolls, weapon damage rolls, ability checks, skill checks, and saving throws for a number of rounds equal to your Charisma modifier (minimum of 1 round). If you fail the opposed Intimidate check, the target shrugs off the insults. A particular target may only be subjected to your Scathing Wit once per day.
