"Clairalience" or 'clear smelling' is, to put it simply, clairvoyance of the sense of
smell. Clairvoyant talents of the mind come in a variety of facets, and Clairalience is one of them.
Clairalience is one of the harder clairvoyant
talents to develop. If you are a beginner at developing psychic
abilities, it might be best to work on other talents that are easier to
work on and more useful. Scents can often be difficult to identify, and
experiencing only scents might leave you confused.
