You can use your voice to shatter ice.
Prerequisite: Bardic music ability, Perform (sing) 6 ranks.
Benefit: By expending one of your daily uses of bardic music, you can cause any unattended nonmagical ice object or portion of ice to explode violently. The target must be within 30 feet, and you must be able to sing in order to shatter the ice. Any creature located in the 5-foot square in which you target with this ability takes piercing damage equal to 2d6 + your Charisma modifier. Creatures made of ice that you specifically target with this effect take double damage.
