A thundering weapon creates a cacophonous roar like thunder whenever it strikes a target with a successful critical hit. The sonic energy does not harm the wielder. A thundering weapon deals an extra 1d8 points of sonic damage on a successful critical hit. If the weapon’s critical multiplier is x3, add an extra 2d8 points of sonic damage instead, and if the multiplier is x4, add an extra 3d8 points of sonic damage. Subjects dealt critical hits by a thundering weapon must make a successful DC 14 Fortitude save or be deafened permanently.
