Enchanting Vocal Modulator, Monofrequency

Magitech

Your voice box has an enchanted digital modulator that can alter its frequency to be supernaturally compelling. As a move action you can calibrate it to a single creature that you have heard and understood speaking or using other sound-based communication. It remains calibrated to that target until you pick a new target. You gain a +2 insight bonus to Bluff, Diplomacy, and Intimidate checks to influence that creature using your voice (not other forms of communication). In addition, you can cast suggestion once per day (DC = 10 + half your character level + your Charisma modifier) as a standard action, targeting a creature your system is calibrated to.
