When this spell is cast, the magic-user can whisper a message and secretly, or openly, point his or her finger while so doing, and the whispered message will travel in a straight line and be audible to the creature pointed at. The message must fit spell duration, and if there is time remaining, the creature who received the message can whisper a reply and be heard by the spell caster. Note that there must be an open and unobstructed path between the spell caster and the recipient of the spell. The material component of the spell is a short piece of copper drawn fine.
