Whispering Wind

1st-level evocation   Casting time: 1 action   Range: 1 mile   Target: up to six creatures wihtin range   Components: V, S, M (a feather)   Duration: 1 round   Classes:   Subclasses:  
You point your finger in a direction and whisper a message of twenty-five words or less, while specifying up to six creatures to be the targets. If a target is in range and in the approximate direction indicated, they (and only they) hear the message carried on the wind. They can reply in a whisper that only you can hear.
  You can cast this spell only when there is a clear path for air to move between you and the targets. The spell doesn’t have to follow a straight line and can travel freely around corners or through openings, but is blocked by solid objects and areas of magical silence.
