You've studied up on the most appropriate insults and unnerving things to say to your opponents. When you make a Taunt check against an opponent who loses the opposed roll and gains the rattled condition as a result, the opponent takes a −4 penalty to all rolls instead of the usual −2. You must be able to communicate verbally with your opponent in an understood language to make them this pissed off.
