Just a few "amplified" magic missile spells I thought up:
Magic Bullets
Evocation [Force]
Level: Sor/Wiz 5
Components: V, S
Casting Time: 1 round
Range: Medium (100 ft. + 10 ft./level)
Targets: Any foes within 15 feet of one another
Duration: Concentration, up to 1 round/lvl.
Saving Throw: None
Spell Resistance: Yes
When this spell completes casting, you may immediately shoot out four magic bullets in quick succession from your palm, unerringly striking the chosen foe(s) and dealing 1 force damage. You must concentrate every turn for the duration of this spell, or it will end prematurely.
Huge Magic Missile
Evocation [Force]
Level: Sor/Wiz 7
Components: V, S
Casting Time: 1 standard action
Range: Medium (100 ft. + 10 ft./level)
Area: 10 ft. wide line extending out to your maximum range
Duration: Instantaneous
Saving Throw: None
Spell Resistance: Yes
You create a huge magic missile, and throw it in a straight line, dealing 5d8 plus 1d8 force damage per two caster levels (maximum 15d8) to every creature caught in the area.
