From publisher blurb: The OSR has become something of a home for the grotesque, the strange, the disgusting and the horrible. Whether that be the deadly oddities and horrors of Lamentations of the Flame Princess or the pecularities of Carcosa – not the mention the many other fringe products – there seems to be a home for the vile, unsettling and surreal. Some of the things that cause the most visceral disgust and reaction in people are bodily fluids – spit, blood, urine and more. Slimes and oozes have always been a big part of fantasy gaming and combining these with the wilder, darker sides of magic and the compulsion to shock and disgust players who come under attack by these things can combine to create some potentially powerful monsters and dark spells. Enjoy these ‘Foul Humours’, created from human excresence.
