Quick Cast: Yes
Requirements: Burning incense in the wind, and a 15 minute ritual. For a witch or warlock, a mere gesture.
Effects: The spell allows the caster to send a message to anyone they have previously met before by simply speaking it onto the wind. Only the person to whom the message is sent can hear it. The message may also take time to get to the person as it travels on the wind to the desired individual.Buffy TVS Spells
