Mist Ferns
There are places in the world where magic has warped the very heart of nature.  Mist ferns are a form of fern that enhances its habitat by summoning clouds of fog, creating a damper climate.  In effect it creates a thin permanent mist.
     It is said that there are ways of forcing the mist fern to create a thick mist equivalent to a fog cloud and that there is a mutant form of the plant that creates a smoke effect (treat as fog cloud except that a Fortitude save (DC 11) is needed every 10 minutes or the character takes 1d6 subdual damage).
    Market Cost: 50 gp (fog), 200 gp (thick fog), and 2,000 gp (smoke).
