A missile of magical energy darts forth from your fingertip and strikes its target, dealing 1d4+1 points of force damage.

The missile strikes unerringly, even if the target is in melee combat or has less than total cover or total concealment. Specific parts of a creature can't be singled out. Inanimate objects are not damaged by the spell.

For every two caster levels beyond 1st, you gain an additional missile--two at 3rd level, three at 5th, four at 7th, and so on. 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 roll damage.
