This magical instrument can be struck once per turn. Its resonant tone lasts for three full rounds. While the chime is resonating, no spell requiring a verbal component can be cast within a 30' radius of it unless the caster is able to make a saving throw vs. breath weapon. After its effects fade, the chime must be rested for at least seven rounds. If it is struck again before this time elapses, no sound issues forth, and a full turn must elapse from that point in time before it can again be sounded.
When this is used by a bard, affected Spellcasters must roll their saving throws with a -1 penalty per three levels of the bard. Elven Minstrels (a bard kit) disrupt any spell that they can themselves cast.
