The Price of Peace
+1 Harmonizing echoblade (rapier): while using bardic music, the Silver Star deals additional sonic damage equal to 1/2 the wielder’s Bard level. Harmonizing: (+1 enchantment), +2 bonus to Perform(sing), and the weapon can pick up the performance and continue bardic music for 10 rounds.
The wielder touches the target with the sword and has the effect of Break enchantment or Remove curse, but makes a Perform(sing) check in place of a caster level check. Also, the Harmonizing effect does not end if the wielder begins another bardic music.
As the user progresses in level, the sword grows stronger.
Stunning surge: On a successful melee attack, you can command this weapon to emit a surge of magical energy. Unless the target succeeds on a Fortitude save (DC 10 + 1/2 your character level + your Cha modifier), it is stunned for 1 round. This ability is usable a number of times per day equal to 1 + your Charisma bonus (if any).
