Bladeleap (PSR)

The spell causes a dagger, dart, or other simple thrown weapon that you're holding to leap out of your hand and fly at a foe you see within range. It will then attack the target, using your spell attack modifier to hit and damage rolls, then return to your hand. If your hand is currently holding something, it hovers in the air next to you. During each of your turns, you may use a bonus action to send the weapon flying to a new target. You must make new ranged spell attack each time to hit

For the purposes of flavour, the thrown weapon can be something larger than a simple thrown weapon, but must use a D4 damage die. Similarly, the spell could also be flavoured as multitudes of items all flying one after the other.
