As a standard action, you can taunt an enemy within 60 feet. Attempt an Intimidate check with the same DC as a check to demoralize that enemy (though this isn't a check to demoralize, so you can't use abilities that would apply to a demoralization attempt, like the rattling presence expertise talent). If you fail, that enemy is off-target until the end of your next turn. If you succeed, that enemy is instead shaken until the end of your next turn. This is an emotion and fear effect.
At 6th level, you can spend 1 Resolve Point to treat a failed Intimidate check for dispiriting taunt as if it were a success.
