Notes

This spell inflicts Force damage instead of Magical damage. Force damage is similar to Magical damage, but only respects half of a target's Magical damage immunity, and does not respect Magical damage resistance.
Since the caster is (on some level) guiding the missiles to their targets, this spell will only target creatures the caster can see.
The spell description is misleading when there are more missiles than targets. The missiles will be distributed evenly among the potential targets until there are fewer missiles than targets, at which point the remainder will be given to the first target. For example, if 8 missiles are fired at three targets, each target will be hit by 2 missiles (accounting for 6 missiles), then the leftover 2 missiles will hit the first target (for a total of 4 hits on the first target).
