Often found floating over campsites of unfortunate travelers drained of all bodily fluids, these blood-red fog banks can be mistaken for colossal vampiric mists.
A sanguinary cloud typically settles over a 60-footradius area, obscuring all sight beyond 5 feet, including darkvision, granting concealment (20% miss chance) to all creatures 5 feet away or farther. Creatures caught within a bank of this deadly fog must succeed at a DC 18 Fortitude save each round or take 1d3 points of Constitution damage as their bodily fluids are forcibly extracted from their pores and mucous membranes and drawn into the crimson mist.
A severe or greater wind disperses a sanguinary cloud, leaving behind a thin sheen of bloody bile.
