[Ambush]

By making a precise punch to the throat, you can render a target unable to speak effectively.

Prerequisite: Improved Unarmed Strike, sneak attack +3d6

Benefit: Your successful sneak attack delivered with an unarmed strike temporarily hinders the target's ability to speak. For the next 3 rounds, the target takes a -5 penalty on any skill check requiring speech and has a 50% chance of failure when casting a spell with a verbal component or activating a magic item with a command word. Multiple uses of this feat don't increase the duration beyond 3 rounds. Using this feat reduces your sneak attack damage by 2d6.

Special: You must be able to reach your foe's neck to use this feat.
