Here is an item I designed... What do you guys think?
HEADBAND OF THE TRICKSTER GNOME
Slot headband; Weight 1 lb.
Price 4,800 GP
Aura moderate illusion; CL 4th
Spellcraft DC= 19 to identify.
Embedded inside this delicated woven silver headband is a wide onyx band. Standing against the band are mid-relief of rotund gnomes frozen in the middle of various activities: running, fighting with sword and shield…
As a quick action, the wearer of the headband can, three times a day, generate an illusionary sound in any spot within his sight not distant of more than 35ft.
At the time of activation, the wearer can choose that sound to be that of an almost-intelligible conversation (this conversation is in fact gibberish and it is impossible to convey intelligible meaning using that item), of rapidly receding footsteps, of a warrior fighting or of hilarious bodily noises.
After casting, the wearer of the headband can displace the origin of the sound as a move action. However, it can never be more than 35ft away from the headband. The sound last until dismissed by the wearer, until the headband is used again or against the newt dusk at which point the number of use per day resets.
Creatures subjected to this illusion can disbelieve it if they succeed on a will save at DC=15. A creature that fails this save is taken by the illusion and is distracted. For example, the illusionary sound of a warrior on the other side of a fighter might cause him to watch his back for an invisible foe. In effect, this would distract him and grant combat advantage in the same fashion than if he truly was flanked by a real opponent.
