    Evocation [Fire]
    Level: Sor/Wiz 9
    Components: V, S
    Casting Time: 1 standard action
    Range: Long (40M)
    Area: Four 13.33-M.-radius spreads; see text
    Duration: Instantaneous
    Saving Throw: None or Reflex half; see text
    Spell Resistance: Yes

    Meteor swarm is a very powerful and spectacular spell that is similar to
    fireball in many aspects. When you cast it, four flaming spheres spring from
    your outstretched hand and streak in straight lines to the spots you select.
    The meteor spheres leave a fiery trail of sparks.

    Once cast, the other flaming spheres will be targeted at 3 different targets
    other then the target selected (if one is valid), in a 10-M radius sphere.

    If you aim a sphere at a specific creature, you may make a ranged touch
    attack to strike the target with the meteor. Any creature struck by one of
    these spheres takes 2d6 points of bludgeoning damage (no save) and receives
    no saving throw against the sphere’s fire damage (see below). If a targeted
    sphere misses its target, it simply explodes at the location of the target.

    Once a sphere reaches its destination, it explodes in a 13.33-meter-radius
    spread, dealing 6d6 points of fire damage to each creature in the area. If
    a creature is within the area of more than one sphere, it must save
    separately against each. (Fire resistance applies to each sphere’s damage
    individually.)

//:: Spell Effects Applied / Notes
//:://////////////////////////////////////////////
    Ok:

    - We target one, and it explodes as normal, if a target is selected,
      it won't be targeted by another.
    - Then, 3 other "missiles" may be fired, up to 3, as long as it isn't us,
      or the target just targeted.
