Libanomancy (also known as livanomancy and knissomancy) is a divination primarily through observing and interpreting burning incense smoke, but which may include the way incense ash falls as well. Like most other methods of divination, during libanomancy a specific question must be asked. The incense smoke provides an answer, but the smoke must be interpreted by a diviner. Libanomancy may be considered a pseudoscience.
