Eamon's Five Blades

The small knife or dagger you have shimmers with arcane energy and five spectral blades appear from the mundane blade. These blades hover around you for the full duration. As a bonus action, you can throw one of these blades towards a creature within 40 feet. Make a ranged spell attack, on a hit the target takes 1d6 Psychic Damage and 1d6 Force Damage. Any unused blades dissapear once the duration is up. 

You can only use these blades on a bonus action.
