Magic Weapon Abilities - Blindsighted
A blindsighted weapon constantly emits a susurrus of whispered notes (Listen DC 10). A wielder actively grasping the weapon gains blindsight to a range of 30 feet. This ability allows the wielder to see invisible creatures and objects, see through darkness, and ignore many forms of concealment, but it does not confer any special immunity to illusions or any special ability to find hidden objects. The weapon's blindsight effect is canceled by silence spells and effects.
