Blade of banishing

A blade of banishing is a magical dagger that is able to destroy magical barriers, illusions or protections upon coming in contact with them. The dagger is always active, cannot be "switched off" and will have this effect whether or not it is being wielded, or it is drawn; it simply needs to come into contact with the magic against which it is acting. A blade such as this was worth around 5,000 gold pieces as of 1368 DR.
