Aura faint transmutation; CL 3rd
Slot weapon, neck, or ring; Price 4,500 gp; Weight —
This tiny dagger has a black leather hilt and a gold-inlaid pattern of stripes and sharp angles on its steel blade, though it can transform into a delicate necklace or ornate finger-ring at your command. You gain a +3 competence bonus on Perception checks while you carry or wear it. You may use it to cast ghost sound once per day.
If you worship a god or goddess of lust or revenge, once per day you may speak a command word to activate fox's cunning. By pricking your finger with the dagger and swearing an oath on your own blood to avenge yourself against a named particular creature (a standard action), you gain a +1 competence bonus on your next attack roll within 1 minute against that creature. Speaking a new vengeance-oath removes the old one, whether or not you have achieved your vengeance.
