Trigger You succeed at a Demoralize check.

You can call upon your former lives and project all of your accumulated frustration, failure, and despair through your eyes at a target, overwhelming their senses. One creature you successfully Demoralized becomes Sickened instead of frightened, with the same condition value. The DC to recover from the sickened condition is your Intimidation DC.
