Circle of Missiles

You create a number of missiles of arcane force equal to 3d4 + your spellcasting modifier.  The missiles hover in a circle around your body.  Upon the casting of this spell, and as a bonus action on turns following this one, you can send up to two of the circling missiles towards a target within range that you can see. Each missile automatically hits for 2d4 force damage. The magic missiles all strike simultaneously, and you can direct them to hit one creature or several.

The missiles will continue to circle you until used or after the duration ends.
