Capnomancy

Capnomancy (otherwise known as libanomancy) signifies a method of divination using smoke. This is done by looking at the movements of the smoke after a fire has been made. A thin, straight plume of smoke is thought to indicate a good omen whereas the opposite is thought of large plumes of smoke. If the smoke touches the ground, this is thought to be a sign that immediate action must be taken to avoid catastrophe.
