Magic Missile (Evocation)
Level: 1 Components: V, S
Range: 6” + 1”/level Casting Time: 1 segment
Duration: Special Saving Throw: None
Area of Effect: One or more
creatures in a 10 square foot area
Explanation/Description: Use of the magic missile spell creates one or more magical missiles which dart forth from the magic-user’s fingertip and unerringly strike their target. Each missile does 2 to 5 hit points (d4 + 1) of damage. If the magic-user has multiple missile capability, he or she can have them strike a single target creature or several creatures, as desired. For each level of experience of the magic-user, the range of his or her magic missile extends 1” beyond the 6” base range. For every 2 levels of experience, the magic-user gains an additional missile, i.e. 2 at 3rd level, 3 at 5th level, 4 at 7th level, etc.
Duration unexplained special is weird too.
