The firearm targeted creates a thunderous report, even if the firearm is not loaded. Every Creature within 15 feet of the Creature wielding or carrying the firearm must succeed at a Fortitude save or be deafened for 1 minute. The Creature wielding or carrying the firearm takes a –4 Penalty on this Saving Throw, and his misfire range increases by 1 for 1d4 rounds. If the firearm was loaded when it was targeted by this spell, that ammunition is wasted.
