Magic Missile

Magic Missile is an iconic 1st level offensive Wizard spell from Dungeons & Dragons, and is literally one of the oldest attack spells in the entire history of the game. It creates one or more "bullets" of magical energy which are then launched at one - or sometimes multiple - targets. In earlier editions, it's functionally a homing attack which hits automatically, with each bullet doing a relatively small amount of damage, but with each bullet doing its own damage roll, the damage can stack up, making it useful for a surprisingly decent interval.

The spell is so iconic that many gamers will use the name as a catch-all for any low-level "fire energy at somebody" type spells. In Warhammer Fantasy, it's even a distinctive category of attack spells.

In Dungeons & Dragons 3rd Edition, the Force Missile Mage is a Wizard Prestige Class that specializes in taking this humble spell and pushing it to new heights.
