Message

You point your finger toward a creature within range and whisper a message. The target (and only the target) hears the message and can reply in a whisper that only you can hear.

You can cast this spell through solid objects if you are familiar with the target and know it is beyond the barrier. Magical silence, 1ft of stone, 1in of common metal, a thin sheet of lead, or 3ft of wood blocks the spell.

The spell doesn't have to follow a straight line and can travel freely around corners or through openings.
