A throttle weapon deals damage only when it is used to grapple a foe, automatically dealing damage with every successful grapple combat maneuver. These are considered attacks for abilities that can increase a weapon’s damage (such as trick attack). All throttle weapons are also grapple weapons. While a target is successfully being grappled with a throttle weapon, it cannot use its airways to speak or make vocalizations of any kind (though other forms of making noise work normally).
