Touch of Silence (Su): With a melee touch attack, you render a target silent (as the spell silence, but only affecting the target) for 1 round. You can use this ability a number of times per day equal to 3 + your Wisdom modifier.

Excommunicate (Su): At 8th level, once per day, you can silence a creature within 30 feet as a standard action. A Will save against DC = 10 + 1/2 your inquisitor level + your Wisdom modifier negates the effect. A creature that fails its save gets a second save 1 round later. If it fails the second save, the target cannot speak, provide verbal components for spells, make use of language-dependent effects, write, pantomime, or take any other action meant to communicate anything more complex than a simple affirmative or negative for 1 day.
