Magic Missile
From Multiversal Omnipedia
Magic missile is a common magical spell enabling the user to fire blasts of magical force.
In earlier editions of AD&D, the spell conjures up a bolt of power with limited capability in the way of damage (ranging from 2-5). The spell is popular, however, for the fact that it never misses a target that it can reach.
It also scales rather well, so that higher level mages can fire multiple missiles simultaneously, directing them at different targets. At a peak of 5 missiles, it remains a spell unlikely to devastate an opposing party, but in singular combat, it can strike down even mid-level opponents rapidly.
