Whispering Tide

A nautical variation of the spell whispering wind, this spell enables the wizard to send a message or cause some desired sound effect in a specific location within range that is familiar to the wizard. The whispering tide can travel over or under the surface of any body of water. It is no more than a mere ripple or gentle current, and usually unnoticed by anyone until it reaches the designated location. It then delivers its message, regardless of whether or not anyone is there to hear it, and dissipates. The wizard may dictate a message of up to 25 words or instead cause the whispering tide to seem to be a faint ripple or splashing sound. The tide can move as slowly as 1 mile per hour, or as quickly as 1 mile per turn. No other spells may be cast through the whispering tide.
