A missile of magical energy darts forth from your fingertip and strikes its target unerringly, dealing 1d4+1 points of force damage.
For every two caster levels beyond 1st, you gain an additional missile - two at 3rd level, three at 5th, four at 7th, and the maximum of five missiles at 9th or higher level. If you shoot multiple missiles, you can have them strike a single creature or several creatures. A single missile can strike only one creature. You must designate targets before you make your roll damage.
