Ghost sound

Ghost sound is a cantrip, or very simple to use spell, learned by all wizards. Ghost sound allows its caster to create the impression of a quiet, whispery-sound. The sound, is not, however, real, but in fact an illusion created by the wizard. Following the Spellplague ghost sound, like all cantrips, became an at-will spell that wizards are capable of casting at any time, without preparation.
